+                       SENDMAIL RELEASE 8
+
+This directory has the latest sendmail software from Berkeley.  See
+doc/op/op.me for a summary of changes since 5.67.
+
+Report any bugs to sendmail@CS.Berkeley.EDU.
+
+The latest version of sendmail is kept on FTP.CS.Berkeley.EDU, directory
+/ucb/sendmail; check there for the latest revision.
+
+There are several related RFCs that you may wish to read -- they are
+available via anonymous FTP to several sites, including nic.ddn.mil
+(directory rfc), ftp.nisc.sri.com (rfc), nis.nsf.net (RFC),
+nisc.jvnc.net (rfc), venera.isi.edu (in-notes), and wuarchive.wustl.edu
+(info/rfc).  They can also be retrieved via electronic mail by sending
+email to one of:
+
+       mail-server@nisc.sri.com
+               Put "send rfcNNN" in message body
+       nis-info@nis.nsf.net
+               Put "send RFCnnn.TXT-1" in message body
+       sendrfc@jvnc.net
+               Put "RFCnnn" as Subject: line
+
+Important RFCs for electronic mail are:
+
+       RFC821  SMTP protocol
+       RFC822  Mail header format
+       RFC974  MX routing
+       RFC976  UUCP mail format
+       RFC1123 Host requirements (modifies 821, 822, and 974)
+       RFC1413 Identification server
+       RFC1341 MIME: Multipurpose Internet Mail Extensions
+       RFC1344 Implications of MIME for Internet Mail Gateways
+
+Other standards that may be of interest (but which are less directly
+relevant to sendmail) are:
+
+       RFC987  Mapping between RFC822 and X.400
+       RFC1049 Content-Type header field (extension to RFC822)
+
+Unfortunately, for a variety of reasons the Makefiles are for the new
+Berkeley "make" and will not work on the old, traditional make.  I urge
+you to get this make from Net2 (available on many public FTP archives).
+Failing that, some directories have a "Makefile.dist" that will work on
+older versions of make (but don't have the niceties included).
+
+Similar comments apply to the man pages -- they use the new Berkeley
+-mandoc macros instead of the -man macros.  You can get these from
+Net2 as well.
+
+IF YOU WANT TO RUN THE NEW BERKELEY DB SOFTWARE:  ****  DO NOT  ****
+use the version that was on the Net2 tape -- it has a number of
+nefarious bugs that were bad enough when I got them; you shouldn't have
+to go through the same thing.  Instead, get a new version via public
+FTP from ftp.CS.Berkeley.EDU, file ucb/4bsd/db.tar.Z.  This software
+is highly recommended; it gets rid of several stupid limits, it's much
+faster, and the interface is nicer to animals and plants.  You will
+also probably find that you have to add -I/where/you/put/db/include
+to the sendmail makefile to get db.h to work properly.
+
+The structure of this directory tree is:
+
+cf             Source for Berkeley configuration files.  These are
+               different than what you've seen before.  They are a
+               fairly dramatic rewrite, requiring the new sendmail
+               (since they use new features).
+contrib                Some contributed tools to help with sendmail.  THESE
+               ARE NOT SUPPORTED by Berkeley -- contact the original
+               authors if you have problems.  (This directory is not
+               on the 4.4BSD tape.)
+doc            Documentation.  If you are getting source, read
+               op.me -- it's long, but worth it.
+mailstats      Statistics printing program.  It has the pathname of
+               sendmail.st compiled in, so if you've changed that,
+               beware.  This isn't all that useful.
+makemap                A program that creates the keyed maps used by the $( ... $)
+               construct in sendmail.  It is primitive but effective.
+               It takes a very simple input format, so you will probably
+               expect to preprocess must human-convenient formats
+               using sed scripts before this program will like them.
+               But it should be functionally complete.
+praliases      A program to print the DBM version of the aliases file.
+               It hasn't been converted to understand the new Berkeley
+               DB format (which we are using).
+rmail          Source for rmail(8).  This is used as a delivery
+               agent for for UUCP, and could presumably be used by
+               other non-socket oriented mailers.  Older versions of
+               rmail are probably deficient.

+8.1C/8.1B      93/06/27
+       Serious security bug fix: it was possible to read any file on
+               the system, regardless of ownership and permissions.
+       If a subroutine returns a fully qualified address, return it
+               immediately instead of feeding it back into rewriting.
+               This fixes a problem with mailertable lookups.
+       CONFIG: fix some M4 frotz (concat => CONCAT)
+
+8.1B/8.1A      93/06/12
+       Serious bug fix: pattern matching backup algorithm stepped by
+               two tokens in classes instead of one.  Found by Claus
+               Assmann at University of Kiel, Germany.
+
+8.1A/8.1A      93/06/08
+       Another mailertable fix....
+
+8.1/8.1                93/06/07
+       4.4BSD freeze.  No semantic changes.
+
+6.65/6.34      93/06/06
+       Fix some lintish problems.
+       Fix some cases where server SMTP behaved poorly when handed bogus
+               input, pointed out by Eric Wassenaar.
+       CONFIG: fix some more (sigh) mailertable bugs -- thanks to
+               Motonori Nakamura of Kyoto University (again).
+
+6.64/6.33      93/06/05
+       Don't send 050 (-v) information after the 250 response to a QUIT
+               command in srvrsmtp -- clients usually close the connection
+               at this point, and it causes bogus error messages.
+       Don't send messages that have errors on input (such as unbalanced
+               parentheses) during SMTP transactions, since a return
+               message has (probably) already been sent.
+       Give better diagnostics on timeouts during network reads, including
+               information similar to the SMTP phase.
+       Fix bug that caused SMTP messages to deliver synchronously; this
+               happened after the DATA 250, and hence caused reading the
+               next command to be delayed.
+       Ignore Errors-To: header unless 'l' (lower case el) header is
+               specified.  The Errors-To: header violates RFC 1123.
+               Errors-To: was only needed to take the place of the
+               envelope sender in the days when most Unix mailers
+               didn't understand about the two kinds of senders.
+       Don't send warning messages in response to automatically generated
+               messages (that is, those From:<>).
+       CONFIG: fix some rather stupid typos in the mailertable code
+               pointed out by Motonori Nakamura of Kyoto University.
+       CONFIG: add confUSE_ERRORS_TO configuration option.
+       CONFIG: if ALWAYS_ADD_DOMAIN is selected, try to use $M
+               (masquerade name) instead of $j.
+       CONFIG: don't add dots to relay names (added in 6.29); it breaks
+               several things, and can be simulated by dot terminating
+               the names of relays.  For example, use:
+                       DBbit.net.relay.
+               (note the trailing dot).
+
+6.63/6.32      93/06/01
+       Fix prototypes to eliminate chars in argument lists -- some
+               compilers are pissy about this.
+       Log protocol ($r) and body type if set so we can determine if
+               the adaptive algorithms are working.
+       Pessimize on locking of database files (particularly for NEWDB
+               databases) during opens.  There were problems with
+               processes opening the file while it was rebuilt; since
+               NEWDB caches heavily, the reader opened an empty file,
+               which is an error.  If your system has the ability to
+               lock atomically on open, this works properly; otherwise,
+               there are race conditions.
+       Check mod time on .pag file instead of .dir in NDBM aliases
+               because the .dir file doesn't get updated for small
+               alias files.  From John Gardiner Myers of CMU.
+       More Solaris portability -- it now compiles on Solaris, but
+               hangs up in gethostbyname().
+       Move setting of RES_DEBUG flag before first myhostname() call
+               so we can see name server traffic on that call.
+       Fsync() queue files.
+       Fix a problem that causes -bi to try to rebuild maps other than
+               the alias file(s).
+       Fix a problem that caused udb to reject entries from any but
+               the first database listed.
+       Rearrange doc subdirectory for 4.4BSD release tape.
+       CONFIG: put $r into the Received line.  This was an oversight.
+       CONFIG: fix typo (call to ruleset 99 should have been rulset 90).
+       CONFIG: move "auxiliary" subroutines to be in ruleset 90-99
+               range -- in the long run, single digit rulesets may
+               become reserved for builtin use by sendmail.
+       CONFIG: fix major problem that causes host aliases (that is,
+               anything in $=w != $j) to not be recognized.  This has
+               been around since 6.30.
+
+6.62/6.31      93/05/28
+       BETA RELEASE
+       Fix recursive syserr (if there is an error printing a syserr
+               message).  This makes the code much less eager to consider
+               a write error as serious.  This also includes some
+               heuristics to be clever about closed connections.
+       Lock NEWDB files during gets.  This requires version 1.5 or later
+               of the db library.  If you have an older version, you
+               can use -DOLD_NEWDB.  This will go away in a few weeks.
+       Fix problem causing aliases that use host maps to get overwritten.
+       Do appropriate byte swapping on port numbers in ident protocol
+               code.  Fix from Allan Johannesen of WPI.
+       Defer opening of map files to the same time as alias files so that
+               the daemon will tend to pick up new versions more promptly.
+       Prototype a bunch more functions.
+       Some Solaris 2.1 changes (still doesn't link though).
+       Try to simplify Makefiles by including more subordinate #defines
+               in conf.h (based on OS type).
+       CONFIG: check for domains if FEATURE(mailertable) is defined.
+               For example, if the host name is "knecht.cs.berkeley.edu"
+               it will search the following mailertable keys:
+                       knecht.cs.berkeley.edu
+                       .cs.berkeley.edu
+                       .berkeley.edu
+                       .edu
+               This could be used to replace the special relays for bitnet
+               and similar nets.
+
+6.61/6.30      93/05/24
+       Fix problem that prevented appending dots on canonified host
+               names.  This breaks tons of config files -- very
+               important fix.
+       Fix improper pointer dereference in response to HELO command.
+       Fix core dump if debugging set in map_rewrite.
+       CONFIG: add FEATURE(always_add_domain) to always attach the
+               local domain (only impacts local mail).
+       CONFIG: try to avoid turning names into $j -- although
+               technically a host can only have one "canonical name",
+               it seems to be common practice to have several.
+
+6.60/6.29      93/05/22
+       Major change: merge alias databases with maps.  This expands and
+               changes the map class interface but fixes a bunch of bugs.
+               The important user-visible change is that the file name
+               in a K line now does not include the ".db" extension; this
+               is added automatically.  Also, the -d (NIS domain) flag is
+               missing from the K config line; use @domain instead.
+               When compiling, the *_MAP names are gone -- just compile
+               in NDBM, NEWDB, and/or NIS support.
+       Announce mailer/host/user triple on -bv flag -- from Brian
+               Bullen of Stirling University.
+       Don't send more than one line in response to HELO -- it confuses
+               Pony Express, which then behaves very badly.  However,
+               this change does send two line 220 greetings, with the
+               second line reading "ESMTP spoken here".  The usersmtp
+               module recognizes this and goes into ESMTP mode regardless
+               of the setting of the "a" mailer flag.  Thus, "a" means
+               "always try EHLO".
+       AIX portability changes (thanks to Christophe Wolfhugel of
+               Herve Schauer Consultants (Paris) for providing me with
+               an INSA account for this purpose).  Lightly tested.  Use
+               -D_AIX3.  This probably breaks compatibility with some
+               older systems (e.g., 4.2bsd) but still works on SunOS
+               4.1.2, Ultrix 4.2A, HP-UX 8.07, OSF/1 T1.3, and AIX 3.2.3.
+       Fix a problem causing an error message loop if the output channel
+               is hosed.
+       Add the Makefiles that I use for various environments -- some are
+               Berkeley make versions and some are old make versions.
+               My makefile for the NeXT box has gotten lost, alas!
+       PRALIASES: support for printing NEWDB databases.  From
+               Michael J. Corrigan of U.C. San Diego.
+       CONFIG: don't pass pseudo-domains to $[ ... $] (if you have
+               a wildcard MX it can have wierd results).  From
+               Christophe Wolfhugel.
+       CONFIG: dot terminate relay hostnames in S0.  From Christophe
+               Wolfhugel.
+
+6.59/6.28      93/05/13
+       Log version with SMTP daemon startup message.
+       Adjust setproctitle to work on NetBSD and BSD/386.
+       Fix null pointer reference in MX fallback code.
+       A bunch of minor fixes from Eric Wassenaar:
+               If deliver cannot execv the mailer, return EX_OSERR
+                       instead of EX_TEMPFAIL (to give better
+                       error messages).
+               Consistently malloc e_message.
+               Catch degenerate case of calling returntosender()
+                       with an empty returnq.
+               MIME reformatting.
+
+6.58/6.28      93/05/13
+       Fix bug that can cause incorrect verbose display of user smtp
+               messages.
+       Disable SMTP VERB command if PRIV_NOEXPN is set (since this
+               could reveal the same information.
+       Allow failure when reading SMTP greeting message to go on to
+               next MX host.
+       Add "MIME-Version: 1.0" header if using MIME (this was NOT
+               included in RFC 1344, but Bill King of Allan-Bradley
+               Company forwarded me email from Nathaniel Borenstein
+               claiming that it was an inadvertent omission).
+       Don't use Content-Type: X-message-header.  According to John
+               Myers of CMU, many MIME readers will completely ignore
+               the data if they don't recognize it.  Instead, just
+               add a blank line to make it a legal (empty) message.
+       Fix problem causing dots to keep getting appended to cached
+               hostnames.  This can cause buffer overrun conditions.
+               The problem was found by Erik Forsberg of Retix,
+               although I used a different bug fix than he provided.
+       Fix parsing of split header/envelope rewriting specs -- from
+               Eric Forsberg.
+       Fix from Eric Wassenaar to correct To: lists in error messages.
+
+6.57/6.28      93/05/11
+       Fix minor glitch causing extra ctladdrs to be output to queue
+               file.  Just an annoyance.
+       Cache results of name server canonification lookups to avoid
+               backed up queue runs.
+       Major rewrite of alias.c: considerable cleanup, plus sample
+               (untested) support for NIS aliases.  The "A" option
+               can now be a comma separated list (or be repeated) --
+               that is, you can have multiple alias databases.  Each
+               database can have the syntax ``class:file''; if no class
+               is specified, the "implicit" class is assumed.  Implicit
+               searches through a list of compiled in types -- hash,
+               dbm, nis, and stab.  Alias files are searched in the
+               order they are listed.  For example:

+       If in Verbose mode (probably from VERB command) run SMTP job

+       Add udb :mailsender as equivalent to owner- for regular aliases.
+       Delete option 8; add option 7 that means the opposite.  That is,

+       Send error messages in encapsulated MIME format.
+       New compile flag "NIS" that turns on NIS alias and NIS map

+       Add "j" option to send error messages in MIME (RFC 1341)
+               encapsulated message format per RFC 1344.  The

+               user agents.
+       Clean up message handling (for display in mailq output).
+       New setproctitle implementation for 4.4bsd.
+       Create files (such as ~/dead.letter) using mode FileMode (the
+               F option value) instead of 0666.
+       Fix bug causing output of EXPN command to not be fully qualified.
+               This may cause some problems with UUCP addresses that
+               will require some config file assistance -- specifically,
+               the $: part has to include the host name for this output
+               to make sense.
+       Fix a problem that sometimes diagnosed errors and still sent the
+               message if the header syntax was bad.
+       Fix a bug that caused an error message to be emailed when sendmail
+               was operating in -bv mode.
+       Add "ListenQueueSize" keyword to daemon options option (OO) to
+               set the queue size parameter passed to listen().  You
+               will normally have to tweak your kernel to up this.
+       Strip spaces off of beginning of message-id before logging (in

+       Tweak compile flags in daemon.c -- there were some cases where
+               it wouldn't work without NETINET.
+       Change *file* mailer to output all the usual default headers

+6.56/6.27      93/05/01
+       Fix problem that causes the fallback mail to postmaster
+               (case ESM_POSTMASTER in savemail()) to not look at
+               aliases (ugh).
+       Some more HPUX tweaking (compile flag hpux => __hpux so it

+       Don't try to flock non-regular files when mailing to a file.
+               In particular, this was a problem if you tried to

+       Fix a wierd bug that can cause senders to be queued as
+               recipients if the name server is down when the mail
+               is initially sent.  This hack just ignores sender
+               deletion (essentially, it sets the MeToo flag) if there
+               is a TEMPFAIL during processing of the sender address.
+               Obscure.
+       Fix a dangling else problem -- from Brian Bullen from University
+               of Stirling, UK.
+       Add the "b" mailer flag to force a blank line on the end of
+               messages.  Some brilliant versions of /bin/mail insist
+               on this but do not add it themselves.
+       Add the "g" mailer flag to prevent user SMTP from sending
+               "MAIL From:<>".  This is only intended to be a
+               transitional gesture, and should not be used if at
+               all possible.  It appears that Berkeley and IDA
+               config files have always handled this properly; the

+       Various patches to XLA code.
+       Fix problem that causes setuid bit on files to be ignored from

+       NIS map fix (was always including trailing null character)
+               from Mike Glendinning of Ingres UK.
+       Add "a" mailer flag to try using ESMTP.  It tries the EHLO
+               command and if that fails falls back to regular SMTP.
+               Also parses EHLO option keywords.  If host supports
+               SIZE extension, this is added to the MAIL FROM:
+               command.
+       Extend "b" option to include a second value which is the
+               maximum message size this server is willing to accept.
+               For example, a value of "10/1000000" says that there
+               must be ten blocks free, and sendmail will reject
+               any message larger than one megabyte.
+       Some portability hooks for NeXT (this could be applicable
+               to Mach in general).  You have to create an empty

+       Turn off DEFNAMES and DNSRCH when getting the hostsignature
+               (i.e., MX records) in level 1 configuration files; this
+               matches the old behaviour.  From Nakamura Motonori of
+               Kyoto University.
+       Improve error message printing -- if sent through an alias,
+               error messages include the name of the alias in the
+               message.  Unfortunately, in order to make this work
+               properly in queue runs, this changes the format of the
+               C line in the qf file.  The relatively uselessness of
+               the previous information was pointed out to me by
+               Allan E Johannesen of WPI.
+       Add XLA compile flag to add hooks to Christophe Wolfhugel's

+       More generalization of socket code for other protocols.
+       Shorten timeouts on reverse name lookups -- since they are done
+               during connection establishment, long timeouts here can
+               cause higher level timeouts.  This mainly serves to accept
+               mail from hosts that do not have proper reverse (PTR) DNS
+               records set up.
+       Reset e_statmsg before each mailer invocation to avoid bogus
+               messages in the log.
+       Redefine $r, $s, and $_ in error envelopes so you don't get
+               incorrect cruft in the error message.  Problem noted by

+       Default IDENTPROTO off for Ultrix and HPUX, which apparently have
+               the interesting "feature" that when they receive a "Host
+               unreachable" message they closes all open connections to
+               that host.  However, some firewall gateways send this message
+               if you try to connect to an unauthorized port, such as the
+               IDENT port (113).  Thus, no email can be received from such
+               hosts.  There is some evidence that versions of Ultrix before
+               4.3 do not have this problem.  Thanks to Tom Ivar Helbekkmo
+               for pointing out this behaviour to me and to Michael Corrigan
+               of U.C. San Diego for informing me about the HPUX problem.
+       Allow IPC mailers to return a colon-separated list of hosts in the
+               $@ clause; these are searched in order as though they were
+               MX records.
+       When sending an error report, print the list of addresses tagged
+               as bad.  Requested by Allan E Johannesen of WPI.
+       Change map function calls to return a status code.  This gets
+               passed back as the result of rewrite.  Parseaddr marks
+               the address as a QUEUEUP address if the return code is
+               EX_TEMPFAIL.  All this to queue properly if the name
+               server is down.  This code is not well tested.  This code
+               changes the interface to map lookup functions (a fifth
+               parameter, int *statp, is added).  Feature requested by
+               Dan Oscarsson.
+       Don't delete quotes (in the dequote map) if there are spaces in
+               the string, since this would cause them to be replaced by
+               the SpaceSub character.
+       Accept BODY=8BITMIME on SMTP MAIL command.  This isn't advertised
+               because the 8BIT to 7BIT translation doesn't exist yet.
+               This does add a "bodytype" field to both envelope and
+               queue file and a -B command line flag to pass the type in
+               during direct invocations.
+       Discard return error messages only on responses to responses to
+               responses, not on responses to responses.  That is, the
+               algorithm is to try return to sender, then return to
+               postmaster, then discard.  Previously it discarded
+               immediately if the return to sender pass failed.
+       CONFIG: back out change to hide unqualified hostnames behind %-hack.

+       Fix reply() to not reset SmtpReplyBuffer on fatal errors; this
+               was supposed to reset SmtpMsg Buffer.  This makes the
+               client side code virtually useless.  Reported by Allan

+       Implement IDA-style $&x for deferred macro expansion.
+       More POSIX compatibility.
+       CONFIG: Hide unqualified hostnames behind %-hack using $s as the

+       CONFIG: Add FEATURE(bitdomain) allowing mapping of BITNET host
+               names to internet domains.  A program contributed by
+               John Gardiner Myers of CMU to create the maps is included
+               in the contrib directory (in the "misc" tar file).

+
+6.51/6.23      93/04/04
+       Add D= mailer flag to specify a path of possible working directories
+               in which to execute the mailer.  This is intended for the
+               prog mailer; some shells can get upset if they don't have
+               access to the current directory.
+       Add RFC 1413 (IDENT) protocol support.  This is only very loosely
+               tested.  This adds a $_ macro to be the authenticated
+               info (in ``user@domain [address]'' form) and debug flag
+               9 to trace the protocol.
+       Check for loopbacks in usersmtp instead of srvrsmtp -- there is no
+               reason for a local agent to not be talking to the localhost
+               (although the inverse is not true).
+       Add a few hooks for automated map rebuilding.  This is certainly
+               not done yet.

+               Eric Wassenaar.
+       Always respond "quickly" to RCPT command; do alias expansion and
+               the like later.  This also means that mail for lists that
+               have errors will be acccepted, and an error sent back
+               later.  This is done by instantiating the queue file
+               and then immediately running and requeueing it.

+               the input "user@a.b.c" failed instead of being properly
+               rewritten as "user@a.<b>.c".
+       Neil also convinced me that it was correct that $~ should match
+               only one token -- the problem is that it's always possible
+               to add another token, so $~ matches far too eagerly.
+
+6.45/6.21      93/03/25
+       Implement multi-word classes (properly!).
+
+6.44/6.21      93/03/25
+       Add X-Authentication-Warning: headers to clue users into possible
+               attempts to forge mail.  This is on the authwarnings
+               privacy flag, but is the default.  Suggested by Bryan
+               Costales of ICSI.
+       Pass default units for convtime in so they can be more reasonable.
+       Allow config files to always add a new Comments: header (i.e.,
+               they will be added even if an old one already exists).
+               Suggested by Bryan Costales of ICSI.
+       Allow config files to delete an existing Return-Path: header.
+               These should only be added at final delivery.  Suggested
+               by Bryan Costales of ICSI.
+       Some debugging additions.  Suggested by Bryan Costales of ICSI.
+       Clean up logging of Family 0 addresses.  Noted by David Muir
+               Sharnoff and others.
+       Add a "dequote" map class.  This allows config files to strip
+               quotes off of addresses.  Note that this is not a builtin
+               map, just a class -- so you have to define the map
+               using the K line.
+       Fix a bug in the queueup() loop getting a locked tf where in
+               very odd cases it can fall off the bottom and core dump.
+               Of course, it was P{r Emanuelsson who found it....
+       Open a new transcript when splitting an envelope.  Problem found
+               by Allan E Johannesen of WPI.
+       Improved error output in endmailer if the mailer core dumps.
+       CONFIG: Fix typo in UUCP mailer definition.
+       CONFIG: Default several of the new options on: eight bit input,
+               privacy flags set to "authwarnings", and message warning
+               set to 4h.
+       CONFIG: Use dequote map.
+
+6.43/6.20      93/03/23
+       Fix problem with assumption of an sa_len field in a generic
+               sockaddr -- it turns out that most vendors haven't
+               picked up this (very important) fix.
+       Change compilation flags for daemon code -- select one or both
+               of NETINET or NETISO, but don't ever set DAEMON manually.
+       CONFIG: add FEATURE(mailertable) to do IDA-style mailertables.
+
+6.42/6.19      93/03/19
+       Use Postmaster as default fallback return address, not root.
+       POSIX changes for file descriptor handling.
+       Diagnose errors writing new queue file.
+       If you change the owner using an owner- alias, also change the
+               error mode to EM_MAIL so that errors don't get dropped
+               into an inappropriate directory.  Problem noted by
+               Allan E Johannesen of WPI.
+       If you are su'ed to root, send email as who you really are, not
+               as root.  From Brian Kantor of U.C. San Diego.
+       Allow warning messages to be sent after a configurable interval
+               has passed without delivery.  The message is sent only
+               once per envelope.  This changes the format of the qf
+               file to have an F line, and the format of the T option
+               to accept take the format "return/warn" (both intervals).
+       Don't force all local names to lower case -- this was left over
+               from the wierd handling of case mapping on aliases.  It
+               is now driven (as expected) by the "u" mailer flag.
+               Problem noted by P{r Emanuelsson.
+       Fix problem that caused headers on returned email to be trashed;
+               they were getting freed, but are still accessible via
+               BlankEnvelope.
+       Fix problem that caused bogus ids to be created on returned
+               mail.
+       Add support for ISO and other non-INET networking.  This is by
+               no means finished yet.  This does assume a lot of other
+               system support, like a version of gethostbyname that
+               returns non-AF_INET addresses.
+       CONFIG: change default on prog mailer to keep upper case in
+               user names (i.e., in the program command line).
+       CONFIG: strip trailing dots off of hosts in uucp mailer before
+               convert to bang format.
+       CONFIG: create new "relay" mailer for $R (LOCAL_RELAY) and $H
+               (MAIL_HUB) delivery that doesn't add local domain.  Note
+               that this violates 821, but is probably "more correct"
+               for what we are trying to do.  Problem pointed out by
+               Michael Graff of Iowa State.
+
+6.41/6.18      93/03/18
+       Clean up unnecessary creates of queue ids (i.e., empty qf files)
+               when not needed, such as when starting up an SMTP
+               connection.
+       Fix problem where split envelopes aren't instantiated in the queue.
+               This is quite a serious bug.
+       Owner- aliases had problems with leading spaces causing a
+               premature delimitation.
+
+6.40/6.18      93/03/18
+       Have ending 250 (after DATA) include the id; suggested by
+               Brian Kantor of UC San Diego.
+       Add logging on envelope splitting.
+       Change queue ids to have one more letter encoding the hour of
+               the day so that during a single day there is a greater
+               likelihood of uniqueness; requested by Brian Kantor.
+
+6.39/6.18      93/03/18
+       Fix minor compile problem if LOCKF is defined.
+       Define size of tobuf in conf.h.  Observed by Toshinari Takahashi
+               of Toshiba.
+       Restore e_sender -- this is equivalent to e_from.q_paddr without
+               decorations such as angle brackets and comments.
+       OSF/1 on Alpha changes from Allan E Johannesen of WPI.
+       CONFIG: fix typo in S3 for list syntax (;: => :;).  Thanks to
+               Christopher Hoover for noting the problem.
+
+6.38/6.17      93/03/17
+       Pass envelope to disconnect to avoid another use of CurEnv, which
+               can apparently end up being null at inopportune times.
+       Log "received from" as "relay=" for consistency (suggested by
+               John Gardiner Myers).
+       Fix major bug in header handling:  if no From: line existed in
+               the header (so sendmail inserts one), and the sender is
+               an alias that has an owner, the From: line shows the
+               owner (as well as the envelope).  Fixed by early binding
+               the headers (which will change debugging output).
+       HPUX portability patches from Michael J. Corrigan of UC San Diego.
+       Some attempts to adapt better to out of open file conditions.
+       Some changes to ctladdr handling in queue files.
+
+6.37/6.17      93/03/16
+       MAJOR CHANGE:  delete e_sender and e_returnpath (why are these
+               different from e_from?) and $< macro.
+       Log correct IP address in relay= field even if the connection
+               times out.
+       Log "received from [RESPONSE]" on EF_RESPONSE messages (from
+               John Gardiner Myers).
+       Fixes to SysExMsg logging (sometimes just got "message: %s"
+               instead of "message: error message"), noted by Eric
+               Wassenaar.  Also reported by Nakamura Motonori.
+       Improvements to MX piggybacking code, from Nakamura Motonori.
+       Fix case where CurHostName points to an auto variable that has
+               been deallocated (from Nakamura Motonori).
+       Fix bug causing newlines to be included in aliases if option
+               "n" (check alias RHS) is set; bug noted by David Muir
+               Sharnoff.
+       Fix problem causing user names that should be mapped to lower
+               case to not be mapped if they are sent during a queue
+               run.  This greatly simplifies the case mapping code.
+               Problem noted by Allan E Johannesen of WPI.
+       Don't do recipient address rewriting in buildaddr.  This
+               improperly did recipient rewriting on sender addresses,
+               and just seems bogus in general -- but the change could
+               break some .cf files.
+       Pass TZ envariable to child processes for System V.
+       CONFIG: allow LOCAL_RULE_1 and LOCAL_RULE_2 if you want to
+               define those rulesets.
+       KNOWN PROBLEM:  I have seen some problems on SunOS that causes
+               the User Data Base to give errors on some addresses.  I
+               have tracked the problem back at least as far as 93.02.15
+               (version 6.22).  Running with debugging on makes it
+               go away, so I conclude that it is referencing uninitialized
+               stack data.  I haven't been able to track this down yet.
+
+6.36/6.16      93/03/08
+       Allow local mailer to specify $@host -- this lets you assign the
+               "foo" part of jgm+foo to $h for passing in to the local
+               mailer.
+       Additional debug printing in getcanonname (show query type).
+       Don't add the e_fromdomain on sender addresses -- this interacts
+               wierdly with the owner- code.
+       Improve delivery logging to not log obvious or meaningless stuff.
+       Include numeric IP address in Received: lines per RFC 1123 section
+               5.2.8.
+       Fixed a bug in checking stat() return value if restrictmailq is
+               set.  Also, check the entire group set instead of just the
+               primary group.  Both from John Gardiner Myers.
+       Don't have usrerr automatically print errno, since this is often
+               misleading.
+       Use transienterror() in makeconnection after connect() fails and
+               in openmailer after execve() fails (from Eric Wassenaar).
+               Also moved transienterror() from util.c to conf.c.
+       Clean up from= logging on response messages.
+       Undo patch allowing prescan to return a null vector -- it breaks
+               too many things.
+       Config: FEATURE(notsticky) lets you use UDB for everything coming
+               in to the machine, even if it is specifically targetted
+               to this machine.  Without it, UDB is bypassed if the user
+               name is fully qualified.
+       Config: fix another minor botch with <> (local mailer wasn't
+               mapping them properly).
+
+6.35/6.15      93/03/05
+       Fix getrealhostname to return null if sinlen <= 0 -- this can
+               occur if stdin is a pipe.
+       Avoid infinite loop in getcanonname if name server return
+               NO_DATA (for example).
+       Config: avoid having C flag qualify list syntax and error syntax.
+
+6.34/6.14      93/03/05
+       Fix logging in deliver to not pass too many parameters to Ultrix
+               versions of syslog.
+       Don't write the pid file until after the daemon has actually
+               opened and conditioned the connection.
+       Consider addresses "different" if their q_uids differ (so that
+               two users forwarding to the same program will be seen
+               as different, rather than the same).
+       Fix problem with bad parameters in main() -- they set ExitStat
+               but don't exit.
+       Fix null pointer references through RealHostName -- painfully
+               discovered by Allan E Johannesen of WPI.
+       Fix bug causing user@@localhost to core dump (yuch).
+       Config: don't put two @host.dom.ain on users in $=E in SMTP
+               mailer.  Also, catch user@ (no host) in ruleset 0.
+
+6.33/6.13      93/03/03
+       Config: add confCW_FILE as the name of the cw configuration file
+               (defaults to /etc/sendmail.cw).  From P{r Emanuelsson.
+       Allow prescan to return a pointer to an empty list -- this is
+               not an error.  Also, clean up error reporting to avoid
+               double errors (prescan reports once, then the caller
+               reports again).
+       Changes to avoid trusting T_ANY queries -- run them, but if you
+               don't get the info you expected, do T_A and T_MX queries
+               anyhow.  This also fixes an oversight where _res.options
+               bits were being ignored.
+       If PRIV_NOVRFY is set, use 252 response code instead of 502 per
+               RFC 1123 section 5.2.3.  It's not 100% clear that this
+               is correct, but it probably works better with stupid
+               mailers that do a VRFY and only check the first digit.
+
+6.32/6.12      93/03/02
+       Fix uninitialized variable "protocol" in smtp code.
+       Include <unistd.h> in sendmail.h -- move towards POSIX/ANSI.
+       Additional hooks for RFC 1427 (ESMTP SIZE extension).  This
+               includes requiring that enoughspace() know the system
+               block size, which will undoubtedly break most ports.
+       Trace flag 19 in use for srvrsmtp.c.
+       Additional logging -- notably the sending mailer name.  This
+               also changes the delivery logging to strict field=value
+               syntax.
+       Fix some problems with messages getting sent even to addresses
+               that had been marked bad -- from Eric Wassenaar.
+       More WIDE changes: accept host name inside [...] as non-MXed
+               host.  This is intended ONLY for use inside firewalled
+               environments, where the MX points at the gateway.
+       Change .cf file conventions so that mapping for <> addresses
+               don't have an @ in them (to avoid confusing the C mailer
+               flag).  Pointed out by Neil Rickert.
+       Config extensions for Sam Leffler's FlexFAX software.
+
+6.31/6.10      93/02/28
+       Fix some more bugs in alias owner code -- there were some wierd
+               cases where an error in a non-aliased name would override
+               the return info in an aliased name with an owner.
+       Changes from WIDE Project, forwarded to me by Nakamura Motonori:
+               Log actual delivery host (after MX et al); from
+                       yasuhiro@dcl.co.jp.
+               Log daemon startup.
+               Deliver Postmaster copies without a body.
+               Better logging of SMTP senders.
+               Send all program email as daemon even when local.
+       As requested in various forms from many people, accept -qIstring
+               to limit queue runs to jobs with queue-id matching string.
+               Similarly for -qRstring for recipients, -qSstring for
+               senders.
+       Initial hooks for ESMTP support (see RFC 1425).
+       Fixed a syntax error in the UUCP mailer specification that caused
+               core dumps on startup.
+       Check for missing A= or P= arguments in mailer definitions.
+
+6.30/6.10      93/02/27
+       Require FROZENCONFIG compilation flag to include frozen
+               configuration code.  Frozen configuration is really
+               not a very good idea any more, particularly in shared
+               library environments.
+       Do better checking of errno after opens of :include: and .forward
+               files to defer delivery on network and other transient
+               errors.  Suggestion from Craig Everhart.
+       Fix minor botch in read timeout macro processing.
+       Add FEATURE(nouucp) to config files for sites that know absolutely
+               nothing about UUCP.
+       Add built cf files to distribution tape and clarify how to build
+               them if you don't have the Berkeley make.
+       Some sizeof(long) portability changes for the Alpha, from Allan
+               E Johannesen.
+       Add "restrictmailq" privacy flag -- if set, only people in the same
+               group as your queue directory can print the queue.  If you
+               set this, be sure you also restrict access to log files....
+       Fix another bug in owner-list stuff that can cause data files to
+               be "lost".
+       Fix a bug with queue runs that cause forwards to yourself to go
+               into alias/forwarding loops.  I'm still iffy about this
+               fix.
+       Fix from Eric Wassenaar for suppression of return message code.
+
+6.29/6.9       93/02/24
+       Fix yet another problem in alias owner code -- put the wrong return
+               address on the enclosed return-to-sender letter.
+
+6.28/6.9       93/02/24
+       Fix botch in alias owner code that caused it to not operate if the
+               error was detected locally.
+
+6.27/6.9       93/02/24
+       M_LOCAL => M_LOCALMAILER to avoid conflict with Ultrix include
+               file <sys/mount.h>.
+       Miscellaneous bug fixes from Eric Wassenaar:
+               sendmail -bv -t logs the from line even though in verify
+                       mode only.
+               sendmail -v can go into queue mode if shouldqueue returns
+                       TRUE.
+       Add route-addr pruning per RFC 1123 section 5.3.3.  This can be
+               disabled using the "R" option.
+       Delete (always undocumented) -R flag (save original recipients);
+               there are ways to syslog(3) these now.
+       Clean up SMTP reply codes -- specify them as needed in the code,
+               instead of in conf.c -- this was needed during the NCP to
+               TCP transition, but seems silly now.  This also changes
+               parameters to message and nmessage.
+       Have mailstats read the .cf file to find the sendmail.st file and
+               get text versions of mailer names.  An initial version of
+               this code was provided by Tuominen Keijo (although the
+               comments indicate the good bits were written by "E.V.").
+       Add yet more System V compatibility hacks.
+       Fix bug in VRFY code (assumes everything must be a local user).
+       Allow specification of any of the hard-wired pathnames in the
+               Makefile.
+       Delete concept of "trusted users" -- this really didn't provide
+               any security anyway, and caused some problems.
+       Delete last vestige of support for the word "at" as an equivalent
+               to the character "@".
+       Propagate owner-foo alias information into the envelope sender.
+               Based on code from John Gardiner Myers.  This is a major
+               semantic change -- beware!
+       Allow $@ on LHS to indicate "match zero" -- this is used to match
+               the null expression.
+
+6.26/6.8       93/02/21
+       Don't "lose" queue runs.  Very important fix from (who else?)
+               Eric Wassenaar.
+       Completely reset state on RSET command -- from Eric Wassenaar.
+       Send error messages and return receipts using an envelope sender
+               of <> regardless of the setting of $n.  Rewriting rules
+               can undo this if they feel the necessity, as might be
+               needed for networks that don't understand the syntax.
+               This is permitted by RFC 821 section 3.6 and required by
+               RFC 1123 section 5.3.3.  THIS REQUIRES VERSION 4 CONFIG
+               FILES because the rulesets must be able to parse <>
+               properly.
+       Don't ever send error messages to "<>" -- they will get sent to
+               the local postmaster or dumped in /usr/tmp/dead.letter
+               instead.  Per RFC 1123 section 5.3.3.
+       Explicitly check for email to yourself as a dotted quad.  You
+               have to call $[ [ ... ] $] to get this.
+       Up the message timeout to five days per RFC 1123 section 5.3.1.1.
+       Make all read timeouts individually configurable, as strongly
+               recommended by RFC 1123 section 5.3.2.
+       Use f_bavail (blocks available to regular users) instead of f_bfree
+               (blocks available to superuser) in free block checks.
+       Change $d macro to be the current time, not the origination time,
+               since this is consistent with how it is used now.
+       Generalization of enoughspace from Eric Wassenaar covering
+               SGI, Apollo, HPUX, Ultrix, and SunOS.
+       Ignore process group signals -- some front ends can do this if
+               you kill a window too quickly.  From Eric Wassenaar.
+       Change umask to 022.
+
+6.25/6.8       93/02/20
+       Close all cached connections before calling mailers and after
+               forking for delivery (caused double closes which resulted
+               in false errors).
+       Add FEATURE(redirect) in config files -- this allows you to alias
+               old addresses to a pointer to the new address that will
+               give a 551 error message, but not deliver the mail.
+       Some code changes to make the 551 errors look pretty.
+       Names of M4 program paths in config files have changed -- they
+               are all XXX_MAILER_PATH now, to match XXX_MAILER_FLAGS.
+       Fix a bug in the QSELFREF code having to do with empty .forward
+               files, reported by Eric Wassenaar.
+       Add option "p" (privacy flags); this allows you to tune how
+               picky the SMTP server will be.  This also adds the
+               confPRIVACY_FLAGS M4 macro in the config files.
+       Add option "b" (minimum blocks free).  If there are fewer than
+               this number of blocks free on the filesystem containing
+               the queue directory, the SMTP MAIL command will return
+               a 452 response and ask you to try again later.  This
+               also adds the confMIN_FREE_BLOCKS M4 macro in the config
+               files.
+       Made VRFY just verify (doesn't expand aliases and .forward files);
+               EXPN does full expansion.  RCPT in queue-only mode also
+               doesn't chase aliases and .forward.
+
+6.24/6.7       93/02/19
+       Increase the number of domain search entries in domain.c to allow
+               for the extra "" entry indicating the root domain.
+               Reported by Nakamura Motonori of Kyoto U.
+       Add a "SMART_HOST" in the configs for UUCP-connected sites that
+               want to forward all mail with extra "@"s to that site.
+               Also allows SMART_HOST, LOCAL_RELAY, and MAIL_HUB to
+               be specified as ``mailer:hostname'' to use an alternate
+               mailer.
+       Clarified and updated some wording in the Operations Guide.
+       Add the "c" mailer flag -- this suppresses all comment parts of
+               addresses (requested by John Curran of NEARnet).
+       Have -v print prompts in -bt mode even if stdin is not a terminal
+               (default behaviour is to be silent if not reading from
+               a terminal).  Suggested by Bryan Costales, ICSI.
+       Move the metacharacters from C0 space (\001-\037) into C1 space
+               (\201-\237).  This also fixes a bunch of potential bugs
+               with G1 characters (\240-\276) in headers relating to
+               negative numbers passed to isspace() et al.
+       Add YP_LAST_MODIFIED and YP_MASTER_NAME to DBM version of alias
+               database if YPCOMPAT is #defined.  Enhancement from
+               Takahiro Kanbe of Fuji Xerox Information Systems Co., Ltd.
+       Add "list" Precedence (-30); this can be used with old sendmails
+               which will map to precedence 0 (which will return error
+               messages).  Suggested by Stephen R. van den Berg.
+       Many bug fixes from Eric Wassenaar of the National Institute for
+                       Nuclear and High-Energy Physics, Amsterdam:
+               Clear timeouts properly on open failures in include().
+               Don't dereference through NULL if no home directory found.
+               Re-establish SIGCHLD signal on System 5 in reapchild().
+               Avoid NULL pointer reference on -pFOO flag.
+               Properly handle backslash escapes in comments.
+               Correctly check reply status on SMTP NOOP command.
+               Properly save SMTP error message if peer gives
+                       "Service Shutting Down" message.
+               Avoid writing to the transcript if it couldn't be opened.
+               Signal errors in SMTP children to parent properly.
+       Handle self references in a list more globally (include a
+               QSELFREF bit in the address flags).  This enhancement
+               was suggested by Eric Wassenaar.
+       Use initgroups() in hpux, even though it's System-V based.  The
+               HASINITGROUPS compile flag can set this on other systems.
+               This HPUX behaviour was pointed out by Eric Wassenaar.
+
+6.23/6.6       93/02/16
+       Clean up handling of LogLevel to make it easier to figure out
+               what's on what level.
+       Change log levels to have some consistency:
+               1    serious system failures, security problems
+               2    lost communications, protocol failures
+               3    other serious failures
+               4    minor errors
+               5    message collection
+               6    vrfy logging, creation of return-to-sender
+               7    delivery failures
+               8    delivery successes
+               9    delivery tempfails (queue ups)
+               10   database expansion
+               >64  debugging
+       Allow IDA-style separated processing on S= and R= in Mailer
+               definition lines.  Note that rulesets 1 and 2 are
+               still used for both addresses as before.  Bruce Lilly
+               gave a convincing argument that RFC976 insists on
+               this behaviour.
+       Added some time zones to arpatounix -- they may not be in the
+               standards, but they are in use.  However, I may delete
+               arpatounix entirely -- there appears to be no reason
+               for it to exist.
+       Change to UUCP mailer (in cf directory) to try to do a saner job.
+               I'm still not certain about this mailer in general.
+
+6.22/6.5       93/02/15
+       Fix bug that prevents saving letters in ~/dead.letter.
+       Don't add angle brackets in VRFY command if angle brackets already
+               exist in the address.
+       Fix bogus error message in udbexpand.
+       Null terminate host buffers in buildaddr (broken in 6.21) --
+               IMPORTANT FIX!!
+
+6.21/6.5       93/02/15
+       Fix another incorrect error message in alias.c, found by Azuma
+               Okamoto.

+               found by Tom Ivar Helbekkmo.
+       Fix problem with quoted :include: entries.
+       Don't duplicate the filename on verbose printing of .forward and
+               :include: contents.
+       Extend size of prescan buffer (to allow bigger addresses).  Also,
+               detect some buffer overflows.
+       Log user SMTP protocol errors (log level 4).
+
+6.20/6.4       93/02/14
+       Fix another problem in the MCI state machine caused when there
+               were errors generated from the other end to commands
+               other than RCPT.
+
+6.19/6.4       93/02/14
+       Include load average support for DEC Alpha running OSF/1.
+       Fix multiple-response problem with errors in MAIL From: line.
+       Fix SMTP reply codes for invalid address syntaxes (give 501;
+               never give multiple error messages for a single message).
+       Fix problem where a cached connection timeout rejects all
+               later connects to that host.
+       Fix incorrect error message if alias.c is compiled with DBM only.
+       Additional changes to fix nested conditionals (from Bruce Lilly).
+       Recover more gracefully from operating system failures, particularly
+               NULL returns from openmailer (from Noritoshi Demizu,
+               OMRON Corporation).
+       Log forward, alias, and userdb expand operations on log level 10;

+       Changes for HPUX 8.07 compatibility.
+
+6.18/6.4       93/02/12
+       Allow any config option to be set using an M4 define.
+       Change UNAME compile flag to HASUNAME for IDA compatibility
+               (besides, it's a better name).
+       Note in README that on SunOS it must be linked -Bstatic.
+       Fairly major change in domain.c to handle wildcard MX records
+               more rationally.  NOTE: the "w" option (no wildcard MX
+               records match local domain) has been eliminated.
+       Fix some unset variable references pointed out by Bruce Lilly.
+       Fix host name in process titles when using cached connection.

+
+6.16/6.3       93/01/28
+       Experimental fix for problem handling errors in the SMTP
+               protocol in conjunction with connection caching.
+       System 5 compatibility changes.
+
+6.15/6.3       93/01/26
+       Fix a bug that causes local mail delivered using -odq to be
+               eliminated as a duplicate (because it matched the
+               ctladdr, now passed in as a C line).  These changes
+               are pretty tricky......
+
+6.14/6.3       93/01/25
+       Add debugging for some MCI errors.
+
+6.13/6.3       93/01/22

+       Fix problem with address delimitor inside quotes.
+       Define $k and $=k to be the UUCP name (from the uname call)

+
+6.10/6.2       93/01/18
+       Implement arpatounix (largely code from Bruce Lilly).
+       Log more info (suggested by John Myers).

+               by John Myers.
+       Fix miscellaneous bugs.
+       (config files:)  Implement MAIL_HUB for all local mail (to handle
+               NFS-mounted directories) as urged by Tom Ivar Helbekkmo
+               of the Norwegian School of Economics.
+
+6.9/6.1        93/01/13
+       Environment handling simplification/bug fix -- child processes
+               get a minimal, fixed environment.  This avoids different

--------------

 
 

-This document describes (in some detail, though undoubtedly not enough!)
-the sendmail configuration files currently in use at Berkeley as distributed
-with version 5.61 of sendmail.  It discusses the configuration file
-directory hierarchy, how the files are processed by m4(1), what functionality
-the files provide, what m4(1) options can be used to produce specific
-results, and goes through an example or two.  It concludes with a list
-of things that will change in the next release of the configuration files.

+               NEW SENDMAIL CONFIGURATION FILES
+
+               Eric Allman <eric@CS.Berkeley.EDU>
+
+               @(#)README      8.1 (Berkeley) 6/27/93
+
+
+This document describes the sendmail configuration files being used
+at Berkeley.  These use features in the new (R6) sendmail, and although
+there is an ``OLDSENDMAIL'' mode, they haven't really been tested on
+old versions of sendmail and cannot be expected to work well.
+
+These configuration files are probably not as general as previous
+versions, and don't handle as many of the wierd cases automagically.
+I was able to simplify by them for two reasons.  First, the network
+has become more consistent -- for example, at this point, everyone
+on the internet is supposed to be running a name server, so hacks to
+handle NIC-registered hosts can go away.  Second, I assumed that a
+subdomain would be running SMTP internally -- UUCP is presumed to be
+a long-haul protocol.  I realize that this is not universal, but it
+does describe the vast majority of sites with which I am familiar,
+including those outside the US.
+
+Of course, the downside of this is that if you do live in a wierd
+world, things are going to get wierder for you.  I'm sorry about that,
+but at the time we at Berkeley had a problem, and it seemed like the
+right thing to do.
+
+This package requires a post-V7 version of m4; if you are running the
+4.2bsd, SysV.2, or 7th Edition version, I suggest finding a friend with
+a newer version.  You can m4-expand on their system, then run locally.
+SunOS's /usr/5bin/m4 or BSD-Net/2's m4 both work.  GNU m4 (which is a
+language unto itself) also works, but I don't intend to work so hard
+to keep this up in the future.  [Note to GNU folks:  the construct
+"define(`FOO')" should work without my having to add a null value.]
+
+IF YOU DON'T HAVE A BERKELEY MAKE, don't despair!  Just run
+"m4 foo.mc > foo.cf" -- that should be all you need.
+
+To get started, you may want to look at tcpproto.mc (for TCP-only
+sites) and uucpproto.m4 (for UUCP-only sites).  Others are versions
+that we use at Berkeley, although not all are in current use.  For
+example, ucbarpa has gone away, but I've left ucbarpa.mc in because
+it demonstrates some interesting techniques.
+
+I'm not pretending that this README describes everything that these
+configuration files can do; clever people can probably tweak them
+to great effect.  But it should get you started.
+
+
++--------------------------+
+| INTRODUCTION AND EXAMPLE |
++--------------------------+
+
+Configuration files are contained in the subdirectory "cf", with a
+suffix ".mc".  They must be run through "m4" to produce a ".cf" file.
+
+Let's examine a typical .mc file (cf/cs-exposed.mc):
+
+       divert(-1)

+       # WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.
+       #
+
+The divert(-1) will delete the crud in the resulting output file.
+The copyright notice is what your lawyers require.  Our lawyers require
+the one that I've included in my files. A copyleft is a copyright by
+another name.
+
+The next line MUST be
+
+       include(`../m4/cf.m4')
+
+This will pull in the M4 macros you will need to make sense of
+everything else.  As the saying goes, don't think about it, just
+do it.  If you don't do it, don't bother reading the rest of this
+file.
+
+       VERSIONID(`<SCCS or RCS version id>')
+
+VERSIONID is a macro that stuffs the version information into the
+resulting file.  We use SCCS; you could use RCS, something else, or
+omit it completely.  This is not the same as the version id included
+in SMTP greeting messages -- this is defined in m4/version.m4.
+
+       DOMAIN(cs.exposed)
+
+This example exposes the host inside of the CS subdomain -- that is,
+it doesn't try to hide the name of the workstation to the outside
+world.  Changing this to DOMAIN(cs.hidden) would have made outgoing
+messages refer to "<username>@CS.Berkeley.EDU" instead of using the
+local hostname.  Internaly this is effected by using
+"MASQUERADE_AS(CS.Berkeley.EDU)".
+
+       MAILER(smtp)
+
+These describe the mailers used at the default CS site site.  The
+local mailer is always included automatically.

+| OSTYPE |
++--------+
+
+Note that cf/cs-exposed.mc omits an OSTYPE macro -- this assumes
+default Computer Science Division environment.  There are several
+explicit environments available: bsd4.3, bsd4.4, hpux, irix, osf1,
+riscos4.5, sunos3.5, sunos4.1, and ultrix4.1.  These change things
+like the location of the alias file and queue directory.  Some of
+these files are identical to one another.
+
+Operating system definitions are easy to write.  They may define
+the following variables (everything defaults, so an ostype file
+may be empty).
+
+ALIAS_FILE             [/etc/aliases] The location of the text version
+                       of the alias file(s).  It can be a comma-separated
+                       list of names.
+HELP_FILE              [/usr/lib/sendmail.hf] The name of the file
+                       containing information printed in response to
+                       the SMTP HELP command.
+QUEUE_DIR              [/var/spool/mqueue] The directory containing
+                       queue files.
+STATUS_FILE            [/etc/sendmail.st] The file containing status
+                       information.
+LOCAL_MAILER_PATH      [/bin/mail] The program used to deliver local mail.
+LOCAL_MAILER_FLAGS     [rn] The flags used by the local mailer.  The
+                       flags lsDFMm are always included.
+LOCAL_SHELL_PATH       [/bin/sh] The shell used to deliver piped email.
+USENET_MAILER_PATH     [/usr/lib/news/inews] The name of the program
+                       used to submit news.
+USENET_MAILER_FLAGS    [rlsDFMmn] The mailer flags for the usenet mailer.
+USENET_MAILER_ARGS     [-m -h -n] The command line arguments for the
+                       usenet mailer.
+SMTP_MAILER_FLAGS      [undefined] Flags added to SMTP mailer.
+UUCP_MAILER_FLAGS      [undefined] Flags added to UUCP mailer.
+HOSTMAP_SPEC           [dbm -o /etc/hostmap] The value for the builtin
+                       hostmap key definition.  You can redefine this
+                       to change the class, flags, and filename of
+                       the hostmap.  The default flag (-o) makes this
+                       map optional.
+
+In addition, the following boolean flags may be defined -- the value
+is ignored.
+
+NEED_DOMAIN            If set, the $j macro is defined as $w.$D.
+                       If not set, $j is defined as $w.  If this is
+                       set, the domain must be defined using the line
+                       DD<domainname> (probably in the domain file,
+                       but possibly in the .mc file).  You will only
+                       need this if you define your system hostname
+                       without a domain (type "hostname" -- if it
+                       has no dots in the output, you qualify) AND
+                       if you are not running the nameserver AND if
+                       the first (canonical) name in /etc/hosts for
+                       your machine has no domain -- OR if you are
+                       running Ultrix or OSF/1 sendmail.  Either of
+                       these is probably a mistake.
+
++---------+
+| DOMAINS |
++---------+
+
+You will probably want to collect domain-dependent defines into one
+file, referenced by the DOMAIN macro.  For example, our Berkeley
+domain file includes definitions for several internal distinguished
+hosts:
+
+UUCP_RELAY     The host that will forward UUCP-addressed email.
+               If not defined, all UUCP sites must be directly
+               connected.
+BITNET_RELAY   The host that will forward BITNET-addressed email.
+               If not defined, the .BITNET pseudo-domain won't work.
+CSNET_RELAY    The host that will forward CSNET-addressed email.
+               If not defined, the .CSNET pseudo-domain won't work.
+LOCAL_RELAY    The site that will handle unqualified names -- that
+               is, names with out an @domain extension.  If not set,
+               they are assumed to belong on this machine.  This
+               allows you to have a central site to store a
+               company- or department-wide alias database.  This
+               only works at small sites, and there are better
+               methods.
+
+The domain file can also be used to define a domain name, if needed
+(using "DD<domain>") and set certain site-wide features.  If all hosts
+at your site masquerade behind one email name, you could also use
+MASQUERADE_AS here.
+
+You do not have to define a domain -- in particular, if you are a
+single machine sitting off somewhere, it is probably more work than
+it's worth.  This is just a mechanism for combining "domain dependent
+knowledge" into one place.
+
++---------+
+| MAILERS |
++---------+
+
+There are fewer mailers supported in this version than the previous
+version, owing mostly to a simpler world.
+
+local          The local and prog mailers.  You will almost always
+               need these; the only exception is if you relay ALL
+               your mail to another site.  This mailer is included
+               automatically.
+
+smtp           The Simple Mail Transport Protocol mailer.  This does
+               not hide hosts behind a gateway or another other
+               such hack; it assumes a world where everyone is
+               running the name server.
+
+uucp           The Unix-to-Unix Copy Program mailer.  Actually, this
+               defines two mailers, "uucp" and "suucp".  The latter
+               is for when you know that the UUCP mailer at the other
+               end can handle multiple recipients in one transfer.
+               When you invoke this, sendmail looks for all names in
+               the $=U class and sends them to the uucp mailer; all
+               names in the $=Y class are sent to suucp.  Note that
+               this is a function of what version of rmail runs on
+               the receiving end, and hence may be out of your control.
+
+usenet         Usenet (network news) delivery.  If this is specified,
+               an extra rule is added to ruleset 0 that forwards all
+               local email for users named ``group.usenet'' to the
+               ``inews'' program.  Note that this works for all groups,
+               and may be considered a security problem.
+
+fax            Facsimile transmission.  This is experimental and based
+               on Sam Leffler's FlexFAX software.  For more information,
+               see below.
+
+
++----------+
+| FEATURES |
++----------+
+
+Special features can be requested using the "FEATURE" macro.  For
+example, the .mc line:
+
+       FEATURE(use_cw_file)
+
+tells sendmail that you want to have it read an /etc/sendmail.cw
+file to get values for class $=w.  The FEATURE may contain a single
+optional parameter -- for example:
+
+       FEATURE(mailertable, dbm /usr/lib/mailertable)
+
+Available features are:
+
+use_cw_file    Read the file /etc/sendmail.cw file to get alternate
+               names for this host.  This might be used if you were
+               on a host that MXed for a dynamic set of other
+               hosts.  If the set is static, just including the line
+               "Cw<name1> <name2> ..." is probably superior.
+               The actual filename can be overridden by redefining
+               confCW_FILE.
+redirect       Reject all mail addressed to "address.REDIRECT" with
+               a ``551 User not local; please try <address>'' message.
+               If this is set, you can alias people who have left
+               to their new address with ".REDIRECT" appended.
+nouucp         Don't do anything special with UUCP addresses at all.
+nocanonify     Don't pass addresses to $[ ... $] for canonification.
+               This would generally only be used by sites that only
+               act as mail gateways or which have user agents that do
+               full canonification themselves.
+notsticky      By default, email sent to "user@local.host" are marked
+               as "sticky" -- that is, the local addresses aren't
+               matched against UDB and don't go through ruleset 5.
+               This features disables this treatment.  It would
+               normally be used on network gateway machines.
+mailertable    Include a "mailer table" which can be used to override
+               routing for particular domains.  The argument of the
+               FEATURE may be the key definition.  If none is specified,
+               the definition used is:
+                       hash /etc/mailertable.db -o
+               Keys in this database must be of the form:
+                       mailer:domain
+bitdomain      Look up bitnet hosts in a table to try to turn them into
+               internet addresses.  The table can be built using the
+               bitdomain program contributed by John Gardiner Meyers.
+               The argument of the FEATURE may be the key definition; if
+               none is specified, the definition used is:
+                       hash /etc/bitdomain.db -o
+               Keys are the bitnet hostname; values are the corresponding
+               internet hostname.
+uucpdomain     Similar feature for UUCP hosts.  The default map definition
+               is:
+                       hash /etc/uudomain.db -o
+               At the moment there is no automagic tool to build this
+               database.
+always_add_domain
+               Include the local host domain even on locally delivered
+               mail.  Normally it is not added unless it is already
+               present.
+
+Other FEATUREs should be defined, but I was trying to keep these
+config files fairly lean and mean.
+
+
++-------+
+| HACKS |
++-------+
+
+Some things just can't be called features.  To make this clear,
+they go in the hack subdirectory and are referenced using the HACK
+macro.  These will tend to be site-dependent.  The release
+includes the Berkeley-dependent "cssubdomain" hack (that makes
+sendmail accept local names in either Berkeley.EDU or CS.Berkeley.EDU;
+this is intended as a short-term aid while we move hosts into
+subdomains.
+
+
++--------------------+
+| SITE CONFIGURATION |
++--------------------+
+
+Complex sites will need more local configuration information, such as
+lists of UUCP hosts they speak with directly.  This can get a bit more
+tricky.  For an example of a "complex" site, see cf/ucbvax.mc.
+
+The SITECONFIG macro allows you to indirectly reference site-dependent
+configuration information stored in the siteconfig subdirectory.  For
+example, the line
+
+       SITECONFIG(uucp.ucbvax, ucbvax, U)
+
+reads the file uucp.ucbvax for local connection information.  The
+second parameter is the local name (in this case just "ucbvax" since
+it is locally connected, and hence a UUCP hostname) and the name of
+the class in which to store the host information.  Another SITECONFIG
+line reads
+
+       SITECONFIG(uucp.ucbarpa, ucbarpa.Berkeley.EDU, W)
+
+This says that the file uucp.ucbarpa contains the list of UUCP sites
+connected to ucbarpa.Berkeley.EDU.  The $=W class will be used to
+store this list.  [The machine ucbarpa is gone now, but I've left
+this out-of-date configuration file around to demonstrate how you
+might do this.]
+
+The siteconfig file (e.g., siteconfig/uucp.ucbvax.m4) contains nothing
+more than a sequence of SITE macros describing connectivity.  For
+example:
+
+       SITE(cnmat)
+       SITE(sgi olympus)

 
 

+The second example demonstrates that you can use two names on the
+same line; these are usually aliases for the same host (or are at
+least in the same company).
+
+
++-------------------+
+| TWEAKING RULESETS |
++-------------------+

 
 

-HIERARCHY:
-----------
+For more complex configurations, you can define special rules.
+The macro LOCAL_RULE_3 introduces rules that are used in canonicalizing
+the names.  Any modifications made here are reflected in the header.

 
 

-The "cf" subdirectory is organized as follows:
+A common use is to convert old UUCP addreses to SMTP addresses using
+the UUCPSMTP macro.  For example:

 
 

-                                       cf
-                                       |
-                       +---------------+---------------+
-                       |               |               |
-                     sitedep           m4              cf
-                       |               |             /    \
-                       *.m4            *.m4        *.mc   *.cf
+       LOCAL_RULE_3
+       UUCPSMTP(decvax,        decvax.dec.com)
+       UUCPSMTP(research,      research.att.com)

 
 

-where the directories contain the following:
+will cause addresses of the form "decvax!user" and "research!user"
+to be converted to "user@decvax.dec.com" and "user@research.att.com"
+respectively.

 
 

-       sitedep         Site dependent parts of configuration files
-                       in m4(1) include files.
+This could also be used to look hosts in a database map:

 
 

-       m4              Site independent parts of configuration files
-                       in m4(1) include files.
+       LOCAL_RULE_3
+       R$* < @ $+ > $*         $: $1 < @ $(hostmap $2 $) > $3

 
 

-       cf              Includes "master configuration" (.mc) files
-                       that include m4 files from ../m4 and ../sitedep.
-                       .mc files are processed by m4(1) and result in
-                       configuration files (.cf).
+This map would be defined in the LOCAL_CONFIG portion, as shown below.

 
 

-In the remainder of this document, all path names are referenced
-relative to the top level "cf" directory.  Hence, the m4 subdirectory
-is called "cf/m4".
+Similarly, LOCAL_RULE_0 can be used to introduce new parsing rules.
+For example, new rules are needed to parse hostnames that you accept
+via MX records.  For example, you might have:

 
 

+       LOCAL_RULE_0
+       R$+ < @ cnmat.Berkeley.EDU >    $#uucp $@ cnmat $: $1

 
 

-WHERE m4(1) FITS INTO ALL OF THIS:
-----------------------------------
+You would use this if you had installed an MX record for cnmat.Berkeley.EDU
+pointing at this host; this rule catches the message and forwards it on
+using UUCP.

 
 

-Configuration files are built by typing "make" in cf/cf.  This
-runs m4(1) on the .mc files in cf/cf and produces .cf files.
+You can also tweak rulesets 1 and 2 using LOCAL_RULE_1 and LOCAL_RULE_2.
+These rulesets are normally empty.

 
 

-The philosophy at Berkeley is to place as much information into
-one .mc file as possible, and then use m4 conditional substitution
-(ifdef, for example) to produce other configuration files from it.
-This results in a substantial reduction of duplicated code that must
-be maintained separately.
+A similar macro is LOCAL_CONFIG.  This introduces lines added after the
+boilerplate option setting but before rulesets, and can be used to
+declare local database maps or whatever.  For example:

 
 

-The main master configuration file that contains all this information
-is "cf/proto.mc".  This file has a number of m4 conditional substitutions
-that can be controlled by other .mc files that include "cf/proto.mc".
+       LOCAL_CONFIG
+       Khostmap hash /etc/hostmap.db
+       Kyplocal nis -m hosts.byname

 
 

-For example, most hosts at Berkeley have only SMTP (TCP) connections
-to other hosts.  A file called "ucbproto.cf" takes care of these
-machines by defining the m4 flags needed to produce only SMTP mailer
-definitions from "cf/proto.mc".  Since this is default behavior, very
-little needs to be defined.

 
 

-But some hosts at Berkeley (e.g., cad.Berkeley.EDU) have both SMTP
-connections and UUCP connections as well.  Thus, they need to
-produce a configuration file that contains both SMTP and UUCP mailer
-definitions, and they need to include a list of directly connected
-UUCP neighbors.  The file "cf/cad.mc" does this by setting the m4
-flags for "cf/proto.mc" that say "(1) I am a UUCP host with hostname "ucbcad",
-(2) a list of my UUCP neighbors can be found in ../sitedep/uucp.cad.m4".
++---------------------------+
+| MASQUERADING AND RELAYING |
++---------------------------+

 
 

-Thus, there are many .mc files in cf/cf that simply define m4 flags and
-then include "cf/proto.mc" to produce a specific configuration file.
+You can have your host masquerade as another using

 
 

-Note:
+       MASQUERADE_AS(host.domain)

 
 

-       IT IS STRONGLY SUGGESTED THAT YOU, THE SYSTEM MANAGER,
-       CONTINUE TO MAINTAIN CONFIGURATION FILES BY USING THIS
-       m4(1) METHOD.  TRYING TO MAINTAIN MULTIPLE .CF FILES
-       ON SEPARATE MACHINES WILL LEAD TO INSANITY.
+This causes outgoing SMTP mail to be labelled as coming from the
+indicated domain, rather than $j.  One normally masquerades as one
+of your own subdomains (for example, it's unlikely that I would
+choose to masquerade as an MIT site).

 
 

+there are always users that need to be "exposed" -- that is, their
+internal site name should be displayed instead of the masquerade name.
+Root is an example.  You can add users to this list using

 
 

-With that out of the way, we should now examine the functionality
-provided by the supplied sendmail configuration files, and then
-talk in detail about the m4(1) options that control this.
+       EXPOSED_USER(usernames)

 
 

-FUNCTIONALITY PROVIDED BY THE SUPPLIED SENDMAIL CONFIGURATIONS:
----------------------------------------------------------------
-
-Mailers:
---------
-
-The sendmail configuration files come with the following mailers:
+This adds users to class E; you could also use something like

 
 

-       local           For delivery of messages to users on the
-                       local machine.
+       FE/etc/sendmail.cE

 
 

-       tcp             For SMTP delivery of messages across the
-                       the Internet.
-
-       tcpld           For SMTP delivery of messages within the
-                       local domain.
+You can also arrange to relay all unqualified names (that is, names
+without @host) to a relay host.  For example, if you have a central
+email server, you might relay to that host so that users don't have
+to have .forward files or aliases.  You can do this using

 
 

-       uucp            For delivery of messages to a UUCP neighbor.
+       define(`LOCAL_RELAY', mailer:hostname)

 
 

-       smtpuucp        For delivery of messages to a UUCP neighbor
-                       with whom we also share Internet connectivity.
+The ``mailer:'' can be omitted, in which case the mailer defaults to
+"smtp".  There are some user names that you don't want relayed, perhaps
+because of local aliases.  A common example is root, which may be
+locally aliased.  You can add entries to this list using

 
 

-The tcp/tcpld mailers and the smtpuucp mailers deserve a little more
-explanation.
+       LOCAL_USER(usernames)

 
 

-The "tcp" and "tcpld" mailers:
-------------------------------
+This adds users to class L; you could also use something like

 
 

-As regards tcp and tcpld: in theory, there should be only one mailer
-here, called "smtp", that deals with addresses in the form "user@host.domain".  
-Everyone on the Internet would use this, regardless of what domain
-they were in.  Host name lookups would be performed via the domain naming
-system (DNS), and no central registry of machine names would be necessary.
+       FL/etc/sendmail.cL

 
 

-Unfortunately, this is not the case.  The MILNET community is still
-in transition towards the DNS, and until this transition is complete,
-they do not have to use the nameserver.  Rather, they can "legally"
-still use the host table supplied by SRI-NIC to translate names to
-addresses.  This means that to be strictly legal, we must send out
-messages in the form "user@host.domain" ONLY FOR machines that are
-registered with SRI NIC.  Machines that are not registered with the
-NIC must be "hidden" behind a relay machine, e.g.,
-user%unregistered_host@registered_host.domain.  This, when MILNET folks
-reply to this, the mail passes through "registered_host.domain" first.
+If you want all mail sent to a centralized hub, as for a shared
+/var/spool/mail scheme, use

 
 

-Currently this "hiding" behind NIC registered hosts is performed by
-the "tcp" mailer.
+       define(`MAIL_HUB', mailer:hostname)

 
 

-Since you don't want to register all the hosts at your site with
-the NIC (and they don't want you to!), the "tcpld" mailer was created.
-The idea here is that you KNOW all the hosts in your local domain
-use the nameserver, so there is no need to hide mail behind a NIC
-registered relay -- that would only slow things down.  So the "tcpld"
-does not do any hiding of unregistered hosts behind a registered relay.
+Again, ``mailer:'' defaults to "smtp".  If you define both LOCAL_RELAY
+and MAIL_HUB, unqualified names and names in class L will be sent to
+the LOCAL_RELAY and other local names will be sent to MAIL_HUB.  For
+example, if are on machine mastodon.CS.Berkeley.EDU, the following
+combinations of settings will have the indicated effects:

 
 

-Eventually the "tcpld" mailer will become the "smtp" mailer mentioned above.

-The "smtpuucp" mailer:
-----------------------
+LOCAL_RELAY set to     mail.CS.Berkeley.EDU      (delivered locally)
+mail.CS.Berkeley.EDU

 
 

-The "smtpuucp" mailer is another fun one.  As time progresses, many
-hosts with whom one has UUCP connections join the Internet.  Unfortunately,
-if the UUCP connection existed for any length of time, people are
-probably used to using it, complete with the bangist syntax that comes
-with UUCP.  As a result, many sites elect to keep their
-UUCP connections even though they have TCP/IP connectivity to the sites
-in question.  This turns out not be such a good idea because of the
-double-queuing incurred by UUCP, explained in the following example.
+MAIL_HUB set to                mammoth.CS.Berkeley.EDU   mammoth.CS.Berkeley.EDU
+mammoth.CS.Berkeley.EDU

 
 

-For concreteness, consider the following scenario: ucbvax.Berkeley.EDU
-(UUCP host "ucbvax") and decvax.dec.com (UUCP host "decvax") have shared
-a cross county UUCP link that is heavily used by many people.  Let's say
-that a piece of mail is routed through the ucbvax-decvax link via UUCP.
-The queueing process is:
+Both LOCAL_RELAY and   mail.CS.Berkeley.EDU      mammoth.CS.Berkeley.EDU
+MAIL_HUB set as above

 
 
 
 

-step   host    action
------  -----   ------
-1      ucbvax  incoming mail is accepted via UUCP
-2      ucbvax  uuxqt is queued to invoke sendmail.
-3      ucbvax  sendmail parses the message.
-4      ucbvax  sendmail passes the message to the UUCP
-               mailer for delivery to decvax.
-5      ucbvax  message is placed in the outgoing UUCP queue for decvax
++-------------------------------+
+| NON-SMTP BASED CONFIGURATIONS |
++-------------------------------+

 
 

-6      decvax  uucico takes the message from ucbvax
-7      decvax  uuxqt is queued to invoke sendmail
-8      decvax  sendmail parses the message
-9      decvax  sendmail passes the message to someplace else.
+These configuration files are designed primarily for use by SMTP-based
+sites.  I don't pretend that they are well tuned for UUCP-only or
+UUCP-primarily nodes (the latter is defined as a small local net
+connected to the rest of the world via UUCP).  However, there is one
+hook to handle some special cases.

 
 

-Note that the message transited the inbound UUCP queue on ucbvax, the sendmail
-queue on ucbvax, the outbound UUCP queue on ucbvax, the inbound UUCP queue
-on decvax, etc.
+You can define a ``smart host'' that understands a richer address syntax
+using:

 
 

-Now, if decvax and ucbvax have SMTP connectivity, the session is more
-manageable:
+       define(`SMART_HOST', mailer:hostname)

 
 

-step   host    action
------  -----   ------
-1      ucbvax  incoming mail is accepted via UUCP
-2      ucbvax  uuxqt is queued to invoke sendmail.
-3      ucbvax  sendmail parses the message
-4a     ucbvax  sendmail delivers it to decvax.dec.com via SMTP.
+In this case, the ``mailer:'' defaults to "suucp".  Any messages that
+can't be handled using the usual UUCP rules are passed to this host.

 
 

-a      decvax  sendmail accepts the message from ucbvax via SMTP.
-8      decvax  sendmail parses the message.
-9      decvax  sendmail passes it to someplace else.
+If you are on a local SMTP-based net that connects to the outside
+world via UUCP, you can use LOCAL_NET_CONFIG to add appropriate rules.
+For example:

 
 

-Note that old steps (5) and (7), the UUCP queueing, are avoided entirely.
+       define(`SMART_HOST', suucp:uunet)
+       LOCAL_NET_CONFIG
+       R$* < @ $* .$m > $*     $#smtp $@ $2.$m $: $1 < @ $2.$m > $3

 
 

-The only trick to the "smtpuucp" mailer is that even though it uses
-SMTP to communicate with its neighbors, it must use the UUCP syntax
-and rewriting rulesets so that the operation is transparent to the
-outside world.  This is easy enough to do.
+This will cause all names that end in your domain name ($m) via
+SMTP; anything else will be sent via suucp (smart UUCP) to uunet.

 
 

-Other functionality:
--------------------

 
 

-Aside from the mailers supplied, the basic configuration files
-support the following features:
++------------------+
+| FlexFAX SOFTWARE |
++------------------+

 
 

-       * Domains.  Addresses of the form "user@host.domain" are
-         considered to be the basic type of address we deal with.
+Sam Leffler's FlexFAX software is still in beta test -- but he expects a
+public version out "later this week" [as of 3/1/93].  The following
+blurb is direct from Sam:

 
 

-       * Fake domains.  Addresses of the form:
+       $Header: /b/source/CVS/src/usr.sbin/sendmail/cf/README,v 1.3 1993/06/28 22:32:56 glass Exp $

 
 

-               user@host.BITNET
-       and
-               user@host.CSNET
+       How To Obtain This Software (in case all you get is this file)

 
 

-         are forwarded to a CSNET relay host and a BITNET relay host,
-         respectively.
+       The source code is available for public ftp on
+           sgi.com                     sgi/fax/v2.1beta.tar.Z
+               (192.48.153.1)

 
 

-         Note: this feature exists for convenience.  As CSNET and
-         BITNET convert to domains, it will go away.  In particular,
-         "user@host.CSNET" is slated to get the axe in the next release.
+       You can also obtain inst'able images for Silicon Graphics machines from
+           sgi.com                     sgi/fax/v2.1beta.inst.tar
+               (192.48.153.1)

 
 

-m4(1) OPTIONS USED IN THE .MC FILES:
-------------------------------------
+       For example,
+           % ftp -n sgi.com
+           ....
+           ftp> user anonymous
+           ... <type in password>
+           ftp> cd sgi/fax
+           ftp> binary
+           ftp> get v2.1beta.tar.Z

 
 

-The following options, from "most important" to "trivial", can be
-used to control what configuration file you get from running m4(1)
-on "cf/proto.mc".  As explained earlier, the standard practice is to
-create an ".mc" file for a particular configuration that contains
-all the m4(1) macro definitions/flags you want, and then have
-that .mc file include "mc/proto.mc".
+       If you cannot use FTP at all, there is a service called "ftpmail"
+       available from gateekeeper.dec.com:  you can send e-mail to this
+       machine and it will use FTP to retrieve files for you and send you the
+       files back again via e-mail.  To find out more about the ftpmail
+       service, send a message to "ftpmail@gatekeeper.dec.com" whose body
+       consists of the single line "help".

 
 

-Macro name             Example (you must include the ` and ')!
-----------             ---------------------------------------
-
-DOMAIN                 `DDBerkeley.EDU'
-
-     This MUST be defined to be your Internet domain.
-
-INTERNET_RELAY         `DAcad.Berkeley.EDU'
-
-     If defined, this will be the machine behind which non-NIC registered
-hosts are hidden, resulting in addresses of the form
-
-       user%host@internet_relay.domain
-
-e.g.,
-
-       moore%prefect@cad.Berkeley.EDU
-
-     If not defined, outgoing addresses will always be of the form
-
-       user@host.domain
-
-regardless of whether "host.domain" is registered with the NIC.
-
-UUCP_NAME              `DUucbcad'
-
-     If defined, includes the UUCP mailer and assumes you have local
-UUCP connections.  The UUCP_NAME macro is used to define your
-canonical UUCP hostname.  See also: UUCP_ALIASES and UUCP_HOSTS_FILE.
-
-UUCP_ALIASES           `CUucbcad cad'
-
-     Used only if UUCP_NAME is defined, this macro lists any UUCP
-aliases for your machine.  See also: UUCP_NAME and UUCP_HOSTS_FILE.
-
-UUCP_HOSTS_FILE                `../sitedep/uucp.cad.m4'
-
-     Used only if UUCP_NAME is defined.  Defines class V of
-local UUCP hosts by including the appropriate m4 file.  See also:
-UUCP_NAME and UUCP_ALIASES.
-
-UUCP_RELAY             `DRcad.Berkeley.EDU'
-
-     If defined, this will be the machine to which non-local UUCP traffic
-is forwarded.  That is, any address that ends in ".UUCP" that is
-not listed in the V class (as defined by UUCP_HOSTS_FILE) will be
-forwarded to the UUCP_RELAY host via the "tcpld" mailer.
-
-UUCP_ONLY              1
-
-     If defined, makes sure that no TCP/IP based mailers will be
-put in the resulting configuration file.  Normally undefined.
-
-SMTPUUCP               `../sitedep/smtpuucp.cad.m4'
-
-     If defined, use SMTP to resolve certain UUCP connections (while
-keeping UUCP syntax).  Should be defined to be a file that
-contains the list of pairs of UUCP names and their corresponding
-Internet names.  See "machdep/smtpuucp.ucbvax.m4" for an example
-of what this should look like.
-
-BITNET_RELAY           `DBjade.Berkeley.EDU'
-
-     If defined, this will be the machine to which BITNET traffic
-(i.e., mail to user@host.bitnet) is forwarded.  If not defined,
-addresses of the form "user@host.bitnet" will bounce.
-
-CSNET_RELAY            `DCrelay.cs.net'
-
-     If defined, this will be the machine to which CSNET traffic
-(i.e., mail to user@host.csnet) is forwarded.  If not defined, addresses
-of that form will bounce.
-
-ARPAKLUDGE             `1'
-
-     If defined, this turns on a kludge to reduce mail load on your
-INTERNET_GATEWAY.  What is done is the following: if mail is outgoing
-to a machine in the ".arpa" domain and we're not registered with the
-NIC, we hide ourselves behind our INTERNET_GATEWAY.  If the machine
-to which mail is being delivered is NOT in the ".arpa" domain, we
-assume they use the domain name system and can reply to our address --
-hence, we don't hide anywhere.
-
-AN EXAMPLE OR TWO:
-------------------
-
-Let's consider a hypothetical system at Foo, Inc.  Foo, Inc. is on the
-ARPA Internet and is the proud owner of the domain "foo.com".  Machines
-in "foo.com" exchange mail with other hosts on the Internet via SMTP.
-Foo, Inc. also has customers with whom they have UUCP links -- these
-links are all on the machine "uucp-gw.foo.com".  Mail to any address
-that ends in ".UUCP" should be forwarded to "uucp-gw.foo.com".  They
-also have a gateway to the bitnet through their local machine
-"bitnet-gw.foo.com"; mail to any address ending in ".bitnet" should go
-there.  They intend to take advantage of the kind folks at CSNET by
-forwarding mail to "host.csnet" to the machine "relay.cs.net".
-
-The master configuration file for a generic machine on the corporate
-ethernet might look like this:
-
-define(DOMAIN, `DDfoo.com')
-define(UUCP_RELAY, `DRuucp-gw.foo.com')
-define(BITNET_RELAY, `DBbitnet-gw.foo.com')
-define(CSNET_RELAY, `DCrelay.cs.net')
-include(proto.mc)
-
-And that's it!  The system manager at "foo.com" would simply install
-this in the "cf" subdirectory, add a production to the make file,
-and type "make foo.cf".  This would run m4(1) on the .mc file and
-we're done.
-
-Now let's turn to the machine "uucp-gw.foo.com".  It obviously needs
-to have the UUCP mailer compiled in, and it needs a list of UUCP
-neighbors with whom it is connected.  Of course, it also needs a TCP/IP
-(SMTP) based mailer so it can talk to the rest of the company.
-On the UUCP network, "uucp-gw.foo.com" is known as "foo".
-The master configuration file might be:
-
-define(DOMAIN, `DDfoo.com')
-define(UUCP_NAME, `DUfoo')
-define(UUCP_ALIASES, `CUfoo')
-define(UUCP_HOSTS_FILE, `../sitedep/uucp.foo.m4')
-define(BITNET_RELAY, `DBbitnet-gw.foo.com')
-define(CSNET_RELAY, `DCrelay.cs.net')
-include(proto.mc)
-
-Note that we didn't define UUCP_RELAY here, since we ARE the UUCP relay.
-
-The file "../sitedep/uucp.foo.m4" contains a list of our UUCP neighbors:
-
-CV     oink
-CV     bletch
-CV     spam
-
-indicating that "uucp-gw.foo.com" is directly connected to three other
-machines via UUCP: "oink", "bletch", and "spam."
-
-
-WHAT WILL BE CHANGING IN THE NEXT RELEASE:
-------------------------------------------
-
-In the next release, the following things should change:
-
-1. The MILNET should have gotten its act together.  This means
-   that the "tcp" mailer goes away.  The "tcpld" mailer will
-   be renamed "smtp".  The "N" class (NIC registered hosts)
-   gets axed.  The ARPAKLUDGE and INTERNET_RELAY  m4(1) options
-   will disappear as well.
-
-2. The CSNET "fake domain" (i.e., user@host.csnet) will cease
-   to be supported.
-
-3. The "smtp" mailer rulesets (currently 17/27) will be rewritten,
-   along with much of rulesets 0 and 3.
+       Internal to Silicon Graphics there are inst'able images on the host
+       flake.asd in the directory /d/dist.  Thus you can do something like:
+
+           % inst -f flake.asd.sgi.com:/d/dist/flexfax
+
+       to install the software on your machine.
+
+       The external distributions come in a compressed or uncompressed tar
+       file.  To extract the source distribution:
+
+           % zcat v2.1beta.tar.Z | tar xf -
+
+       (uncompress and extract individual files in current directory).  To
+       unpack and install the client portion of the inst'able distribution:
+
+           % mkdir dist
+           % cd dist; tar xf ../v2.1beta.inst.tar; cd ..
+           % inst -f dist/flexfax
+           ...
+           inst> go
+
+       (Note, the dist subdirectory is because some versions of inst fail if
+       the files are in the current directory.) Server binaries is also
+       included in the inst'able images as flexfax.server.*.  It is not
+       installed by default, so to get it also you need to extract the do:
+
+           % inst -f flexfax
+           ...
+           inst> install flexfax.server.*
+           inst> go
+
+       The SGI binaries were built for Version 4.0.5 of the IRIX operating
+       system.  They should work w/o problem on earlier versions of the
+       system, but I have not fully tested this.  Also, note that to install a
+       server on an SGI machine, you need to have installed the Display
+       PostScript execution environment product (dps_eoe).  Otherwise, the fax
+       server will not be able to convert PostScript to facsimile for
+       transmission.
+
+       If you are working from the source distribution, look at the file README
+       in the top of the source tree.  If you are working from the inst images,
+       you need to run faxaddmodem to setup and configure your fax modem.  Do
+       man faxaddmodem for more information.
+
+Also from Sam:
+
+       A mailing list for users of this software is located on sgi.com.
+       If you want to join this mailing list or have a list-related request
+       such as getting your name removed from it, send a request to
+
+           flexfax-request@sgi.com
+
+       Submissions (including bug reports) should be directed to:
+
+           flexfax@sgi.com

++--------------------------------+
+| TWEAKING CONFIGURATION OPTIONS |
++--------------------------------+
+
+There are a large number of configuration options that don't normally
+need to be changed.  However, if you feel you need to tweak them, you
+can define the following M4 variables.  This list is shown in four
+columns:  the name you define, the default value for that definition,
+the option or macro that is affected (either Ox for an option or Dx
+for a macro), and a brief description.  Greater detail of the semantics
+can be found in the Installation and Operations Guide.
+
+Some options are likely to be deprecated in future versions -- that is,
+the option is only included to provide back-compatibility.  These are
+marked with "*".

+
+
++-----------+
+| HIERARCHY |
++-----------+
+
+Within this directory are several subdirectories, to wit:
+
+m4             General support routines.  These are typically
+               very important and should not be changed without
+               very careful consideration.
+
+cf             The configuration files themselves.  They have
+               ".mc" suffixes, and must be run through m4 to
+               become complete.  The resulting output should
+               have a ".cf" suffix.
+
+ostype         Definitions describing a particular operating
+               system type.  These should always be referenced
+               using the OSTYPE macro in the .mc file.  Examples
+               include "bsd4.3", "bsd4.4", "sunos3.5", and
+               "sunos4.1".
+
+domain         Definitions describing a particular domain, referenced
+               using the DOMAIN macro in the .mc file.  These are
+               site dependent; for example, we contribute "cs.exposed.m4"
+               and "cs.hidden.m4" which both describe hosts in the
+               CS.Berkeley.EDU subdomain; the former displays the local
+               hostname (e.g., mammoth.CS.Berkeley.EDU), whereas the
+               latter does its best to hide the identity of the local
+               workstation inside the CS subdomain.
+
+mailer         Descriptions of mailers.   These are referenced using
+               the MAILER macro in the .mc file.
+
+sh             Shell files used when building the .cf file from the
+               .mc file in the cf subdirectory.
+
+feature                These hold special orthogonal features that you might
+               want to include.  They should be referenced using
+               the FEATURE macro.
+
+hack           Local hacks.  These can be referenced using the HACK
+               macro.  They shouldn't be of more than voyeuristic
+               interest outside the .Berkeley.EDU domain, but who knows?
+               We've all got our own peccadilloes.
+
+siteconfig     Site configuration -- e.g., tables of locally connected
+               UUCP sites.
+
+
++------------------------+
+| ADMINISTRATIVE DETAILS |
++------------------------+
+
+The following sections detail usage of certain internal parts of the
+sendmail.cf file.  Read them carefully if you are trying to modify
+the current model.  If you find the above descriptions adequate, these
+should be {boring, confusing, tedious, ridiculous} (pick one or more).
+
+RULESETS (* means built in to sendmail)
+
+   0 * Parsing
+   1 * Sender rewriting
+   2 * Recipient rewriting
+   3 * Canonicalization
+   4 * Post cleanup
+   5 * Local address rewrite (after aliasing)
+  1x   mailer rules (sender qualification)
+  2x   mailer rules (recipient qualification)
+  90   Mailertable host stripping
+  96   Bottom half of Ruleset 3 (ruleset 6 in old sendmail)
+  97   Hook for recursive ruleset 0 call (ruleset 7 in old sendmail)
+
+
+MAILERS
+
+   0   local, prog     local and program mailers
+   1   smtp            SMTP channel
+   2   uucp            UNIX-to-UNIX Copy Program
+   3   netnews         Network News delivery
+   4   fax             Sam Leffler's FlexFAX software
+
+
+MACROS

+   O
+   P
+   Q
+   R   Relay (for unqualified names)
+   S   Smart Host
+   T
+   U   my UUCP name (if I have a UUCP connection)
+   V   UUCP Relay (class V hosts)
+   W   UUCP Relay (class W hosts)

+   Y   UUCP Relay (all other hosts)
+   Z   Version number
+
+
+CLASSES
+
+   A
+   B
+   C
+   D
+   E   addresses that should not seem to come from $M
+   F   hosts we forward for
+   G
+   H
+   I
+   J
+   K
+   L   addresses that should not be forwarded to $R
+   M
+   N
+   O   operators that indicate network operations (cannot be in local names)
+   P   top level pseudo-domains: BITNET, FAX, UUCP, etc.
+   Q
+   R
+   S
+   T
+   U   locally connected UUCP hosts
+   V   UUCP hosts connected to relay $V
+   W   UUCP hosts connected to relay $W
+   X   UUCP hosts connected to relay $X
+   Y   locally connected smart UUCP hosts
+   Z
+   .   the class containing only a dot
+
+
+M4 DIVERSIONS
+
+   1   Local host detection and resolution
+   2   Local Ruleset 3 additions
+   3   Local Ruleset 0 additions
+   4   UUCP Ruleset 0 additions
+   5   locally interpreted names (overrides $R)
+   6   local configuration (at top of file)
+   7   mailer definitions
+   8   special local name recognition (late in ruleset 3)
+   9   special local rulesets (1 and 2)

+# $u = $users[0] : the current address being expanded
+# $names{"$users[0] *** $server"} : the 'name' associated with the address
+# $mxbacktrace{"$users[0] *** $server"} : record of mx expansion
+# $mx_secondary{$server} : other mx relays at the same priority
+# $domainify_fallback{"$users[0] *** $server"} : alternative names to try 
+#      instead of $server if $server doesn't work
+# $temporary_redirect{"$users[0] *** $server"} : when trying alternates,

+.SH NAME
+expn \- recursively expand mail aliases
+.SH SYNOPSIS
+.B expn
+.RI [ -a ]
+.RI [ -v ]
+.RI [ -w ]
+.RI [ -d ]
+.IR user [@ hostname ]
+.RI [ user [@ hostname ]]...
+.SH DESCRIPTION
+.B expn
+will use the SMTP
+.B expn
+and 
+.B vrfy
+commands to expand mail aliases.  
+It will first look up the addresses you provide on the command line.
+If those expand into addresses on other systems, it will 
+connect to the other systems and expand again.  It will keep 
+doing this until no further expansion is possible.
+.SH OPTIONS
+The default output of 
+.B expn
+can contain many lines which are not valid
+email addresses.  With the 
+.I -aa
+flag, only expansions that result in legal addresses
+are used.  Since many mailing lists have an illegal
+address or two, the single
+.IR -a ,
+address, flag specifies that a few illegal addresses can
+be mixed into the results.   More 
+.I -a
+flags vary the ratio.  Read the source to track down
+the formula.  With the
+.I -a
+option, you should be able to construct a new mailing
+list out of an existing one.
+.LP
+If you wish to limit the number of levels deep that 
+.B expn
+will recurse as it traces addresses, use the
+.I -1
+option.  For each 
+.I -1
+another level will be traversed.  So, 
+.I -111
+will traverse no more than three levels deep.
+.LP
+The normal mode of operation for
+.B expn
+is to do all of its work silently.
+The following options make it more verbose.
+It is not necessary to make it verbose to see what it is
+doing because as it works, it changes its 
+.BR argv [0]
+variable to reflect its current activity.
+To see how it is expanding things, the 
+.IR -v ,
+verbose, flag will cause 
+.B expn 
+to show each address before
+and after translation as it works.
+The 
+.IR -w ,
+watch, flag will cause
+.B expn
+to show you its conversations with the mail daemons.
+Finally, the 
+.IR -d ,
+debug, flag will expose many of the inner workings so that
+it is possible to eliminate bugs.
+.SH ENVIRONMENT
+No enviroment variables are used.
+.SH FILES
+.PD 0
+.B /tmp/expn$$
+.B temporary file used as input to 
+.BR nslookup .
+.SH SEE ALSO
+.BR aliases (5), 
+.BR sendmail (8),
+.BR nslookup (8),
+RFC 823, and RFC 1123.
+.SH BUGS
+Not all mail daemons will implement 
+.B expn
+or
+.BR vrfy .
+It is not possible to verify addresses that are served
+by such daemons.
+.LP
+When attempting to connect to a system to verify an address,
+.B expn
+only tries one IP address.  Most mail daemons
+will try harder.
+.LP
+It is assumed that you are running domain names and that 
+the 
+.BR nslookup (8) 
+program is available.  If not, 
+.B expn
+will not be able to verify many addresses.  It will also pause
+for a long time unless you change the code where it says
+.I $have_nslookup = 1
+to read
+.I $have_nslookup = 
+.IR 0 .
+.LP
+Lastly, 
+.B expn
+does not handle every valid address.  If you have an example,
+please submit a bug report.

+Document Revision Control Information:
+X   $Author: glass $
+X   $Source: /b/source/CVS/src/usr.sbin/sendmail/contrib/mmuegel,v $
+X   $Revision: 1.2 $ of $Date: 1993/06/28 22:33:06 $
+-------------------------------------------------------------------------------
+X
+1. Introduction
+---------------
+X
+These tools may be of use to those sites using sendmail. Both are written in
+Perl. Our site, Mot.COM, receives a ton of mail being a top-level domain
+gateway. We have over 24 domains under us. Needless to say, we must have
+a robust mail system or my head, and others, would be on the chopping block.
+X
+2. Description
+--------------
+X
+The first tool, cqueue, checks the sendmail queue for problems. We use
+it to flag problems with subdomain mail servers (and even our own servers
+once in a while ;-). We run it via a cron job every hour during the day.
+You may find this too frequent, however. 
+X
+The other program, postclip, is used to "filter" non-deliverable NDNs that
+get sent to our Postmaster account now and then. This ensures privacy of
+e-mail and helps avoid disk problems from huge NDNs. It is different than
+a brute force "just keep the header" approach because it tries hard to keep
+other parts of the message that look like non-delivery information.
+X
+Both have been used for some time at our site with no problems. Everything 
+you need should be in this distribution: source, manual pages, and support 
+libs. See the manual pages for a complete description of each tool.
+X
+3. Installation
+---------------
+X
+No fancy Makefile simply because these tools are all under a large
+hierarchy at my site. Installation should be a snap, however. Install
+the nroff(1) man(5) manual pages from the man subdirectory to the
+appropriate directory on your system. This might be something like
+/usr/local/man/man1.
+X
+Next, install all of the Perl libraries located in the lib subdirectory
+to your Perl library area. /usr/local/lib/perl is a good bet. The person
+who installed Perl at your site will be able to tell you for sure. 
+X
+Finally, you need to install the programs. Note that cqueue wants to
+run setuid root by default. This is because the sendmail queue is normally
+only readable by root or some special group. In order to let any user
+run this suidperl is used. suidperl allows a Perl program to run with the
+privileges of another user. 
+X
+You will have to edit both the cqueue and postclip programs to change
+the #! line at the top of each. Just change the pathname to whatever is
+appropriate on your system. Note that Larry Wall's fixin program from
+the Camel book can also be used to do this. It is very handy. It changes
+#! lines by looking at your PATH.
+X
+If you do not have suidperl on your system change the #! line in cqueue
+to reference perl instead of suidperl.
+X
+You may also wish to change some constants in cqueue. $DEF_QUEUE should be
+changed to your queue directory if it is not /usr/spool/mqueue. $DEF_TIME
+could be changed easy enough also. It is the time spec for the time duration
+after which a mail message will be reported on if the -a option has not been
+specified. See the manual page for more information and the format of this
+constant (same as the -t argument). Then again, neither of these has to
+be changed. Command line options are there to override their default
+values.
+X
+After you have edited the programs as necessary, all that remains is to
+install them to some executable directory. Install postclip mode 555
+and cqueue mode 4555 with owner root (if using suidperl) or mode 555
+(if not using suidperl).
+X
+4. Gripes, Comments, Etc
+------------------------
+X
+If you start using either of these let me know. I have other mail tools I
+will likely post in the future if these prove useful. Also, if you think
+something is just plain dumb/wrong/stupid let me know!
+X
+Cheers,
+-Mike

+;#     as modified by Marion Hakanson (hakanson@ogicse.ogi.edu).
+;#
+;#  Unlike date(1), unknown format tags are silently replaced by "".
+;#
+;#  defaultTZ is a blatant hack, but I wanted to be able to get date(1)
+;#     like behaviour by default and there does'nt seem to be an easy (read
+;#     portable) way to get the local TZ name back...
+;#
+;#     For a cheap date, try...

+;# New_Getopts
+;#
+;# Does not care about order of switches, options, and arguments like 
+;# getopts.pl. Thus all non-switches/options will be kept in ARGV even if they
+;# are not at the end. If $Pass_Invalid is set all unkown options will be
+;# passed back to the caller by keeping them in @ARGV. This is useful when
+;# parsing a command line for your script while ignoring options that you
+;# may pass to another script. If this is set New_Getopts tries to maintain 
+;# the switch clustering on the unkown switches.
+;#
+;# Accepts the special argument -usage to print the Usage string. Also accepts 
+;# the special option -version which prints the contents of the string 
+;# $VERSION. $VERSION may or may not have an embeded \n in it. If -usage 
+;# or -version are specified a status of -1 is returned. Note that the usage
+;# option is only accepted if the usage string is not null.
+;# 
+;# $Switches is just like the formal arguemnt of getopts.pl. $Usage is a usage
+;# string with or without a trailing \n. *Switch_To_Order is an optional
+;# pointer to the name of an associative array which will contain a mapping of
+;# switch names to the order in which (if at all) the argument was entered.
+;#
+;# For example, if @ARGV contains -v, -x, test:
+;#
+;#    $Switch_To_Order {"v"} = 1;
+;#    $Switch_To_Order {"x"} = 2;
+;#
+;# Note that in the case of multiple occurances of an option $Switch_To_Order
+;# will store each occurance of the argument via a string that emulates
+;# an array. This is done by using join ($;, ...). You can retrieve the
+;# array by using split (/$;/, ...).
+;#
+;# *Split_ARGV is an optional pointer to an array which will conatin the
+;# original switches along with their values. For the example used above 
+;# Split_ARGV would contain:
+;#
+;#   @Split_ARGV = ("v", "", "x", "test");
+;#
+;# Another exciting ;-) feature that newgetopts has. Along with creating the 
+;# normal $opt_ scalars for the last value of an argument the list @opt_ is 
+;# created. It is an array which contains all the values of arguments to the 
+;# basename of the variable. They are stored in the order which they occured 
+;# on the command line starting with $[. Note that blank arguments are stored 
+;# as "". Along with providing support for multiple options on the command 
+;# line this also provides a method of counting the number of times an option 
+;# was specified via $#opt_.
+;#
+;# Automatically resets all $opt_, @opt_, %Switch_To_Order, and @Split_ARGV
+;# variables so that New_Getopts may be called more than once from within
+;# the same program. Thus, if $opt_v is set upon entry to New_Getopts and 
+;# -v is not in @ARGV $opt_v will not be set upon exit.
+;#
+;# Arguments:
+;#    $Switches, $Usage, $Pass_Invalid, *Switch_To_Order, *Split_ARGV
+;#
+;# Returns:
+;#    -1, 0, or 1 depending on status (printed Usage/Version, OK, not OK)

+;#     automatically word-wrapped to fit in $Columns. 
+;#
+;#    + \n'd are maintained and are not folded.
+;#
+;#    + $Offset        is pre-pended before each separate line of text. 
+;#
+;#    + If $Offset_Once        is $TRUE $Offset will only appear on the first line.
+;#      All other lines will be indented to match the amount of whitespace of
+;#      $Offset.
+;#
+;#    + If $Bullet_Indent is $TRUE $Offset will only be applied to the begining
+;#      of lines as they occured in the original $String. Lines that are created
+;#      by this routine will always be indented by blank spaces.
+;#
+;#    + If $Columns is 0 no word-wrap is done. This might be useful to still
+;#      to offset each line in a buffer.
+;#
+;#    + If $Split_Expr is supplied the string is split on it. If not supplied

+.SH NAME
+\*(mp - check sendmail queue for problems
+.SH SYNOPSIS
+.IP \*(mp 7 
+[ \fB-abdms\fR ] [ \fB-q\fR \fIqueue-dir\fI ] [ \fB-t\fR \fItime\fR ] 
+[ \fB-u\fR \fIusers\fR ] [ \fB-w\fR \fIwidth\fR ]
+.SH DESCRIPTION
+Reports on problems in the sendmail queue. With no options this simply
+means listing messages that have been in the queue longer than a default
+period along with a summary of queue mail by host and status message.
+.SH OPTIONS
+.IP \fB-a\fR 14
+Report on all messages in the queue. This is equivalent to saying \fB-t\fR 0s.
+You may like this command so much that you use it as a replacement for
+\fBmqueue\fR. For example:
+.sp 1
+.RS
+.RS
+\fBalias mqueue cqueue -a\fR
+.RE
+.RE
+.IP \fB-b\fR 14
+Also report on bogus queue files. Those are files that
+have data files and no control files or vice versa.
+.IP \fB-d\fR
+Print a detailed report of mail messages that have been queued longer than
+the specified or default time. Information that is presented includes:
+.RS
+.RS
+.IB
+Sendmail queue identifier.
+.IB
+Date the message was first queued.
+.IB
+Sender of the message.
+.IB
+One or more recipients of the message.
+.IB
+An optional status of the message. This usually indicates why the message
+has not been delivered.
+.RE
+.RE
+.IP \fB-m\fR 14
+Mail off the results if any problems were found.
+Normaly results are printed to stdout. If this option
+is specified they are mailed to one or more users. Results
+are not printed to stdout in this case. Results are \fBonly\fR
+mailed if \*(mp found something wrong.
+.IP "\fB-q\fR \fIqueue-dir\fI"
+The sendmail mail queue directory. Default is \fB/usr/spool/mqueue\fR or
+some other site configured value.
+.IP "\fB-t\fR \fItime\fR"
+List messages that have been in the queue longer than
+\fItime\fR. Time should of the form:
+.sp 1
+.RS
+.RS
+(<number>(s|m|h|d))+
+.sp 1
+.RE
+.RE
+.RS 14
+The second portion of the above definition
+specifies seconds, minutes, hours, or
+days, respectfully. The first portion is the number of
+those units. There can be any number of such specifiers.
+As an example, 1h30m means 1 hour and 30 minutes.
+.sp 1
+The default is 2 hours.
+.RE
+.IP \fB-s\fR 14
+Print a summary of messages that have been queued longer than
+the specified or default time. Two separate types of summaries are printed.
+The first summarizes the queue messages by destination host. The host name
+is gleaned from the recipient addresses for each message.
+Thus the actual host names for this summary should be taken with a grain
+of salt since ruleset 0 has not been applied to the address the host was
+taken from nor were MX records consulted. It would be possible to add
+this; however, the execution time of the script would increase 
+dramatically. The second summary is by status message.
+.IP "\fB-u\fR \fIusers\fR"
+Specify list of users to send a mail report to other than
+the invoker. This option is only valid when \fB-m\fR has been
+specified. Multiple recipients may be separated by spaces.
+.IP "\fB-w\fR \fIwidth\fR"
+Specify the page width to which the output should tailored. \fIwidth\fR
+should be an integer representing some character position. The default is
+80 or some other site configured value. Output is folded neatly to match 
+\fIwidth\fR.

+.ds mp \fBpostclip\fR
+.SH NAME
+\*(mp - send only the headers to Postmaster
+.SH SYNOPSIS
+\*(mp [ \fB-v\fR ] [ \fIto\fR ... ]
+.SH DESCRIPTION
+\*(mp  will forward non-delivery reports to a postmaster after deleting the body
+of the message. This keeps bounced mail private and helps to avoid disk space problems. \*(mp tries its best to keep as much of the header trail as possible.
+Hopefully only the original body of the message will be filtered. Only messages
+that have a subject that begins with 'Returned mail:' are filtered. This
+ensures that other mail is not accidently mucked with. Finally, note that
+\fBsendmail\fR is used to deliver the message after it has been (possibly)
+filtered. All of the original headers will remain intact.
+.sp 1 
+You can use this with any \fBsendmail\fR by modifying the Postmaster alias.
+If you use IDA \fBsendmail\fR you could add the following to <machine>.m4:
+.sp 1
+.RS
+define(POSTMASTERBOUNCE, mailer-errors)
+.RE
+.sp 1
+In the aliases file, add a line similar to the following:
+.sp 1
+.RS
+mailer-errors: "|/usr/local/bin/postclip postmaster"
+.RE
+.SH OPTIONS
+.IP \fB-v\fR
+Be verbose about delivery. Probably only useful when debugging \*(mp.
+.IP \fIto\fR
+A list of one or more e-mail ids to send the modified
+Postmaster messages to. If none are specified postmaster
+is used.

+Subject: contrib/rcpt-streaming
+Date:    Fri,  4 Jun 1993 13:54:06 -0400 (EDT)
+To:      sendmail@cs.berkeley.edu
+
+This patch implements "RCPT streaming" in sendmail version 6.  This
+patch is not an official part of sendmail.  Please report all problems
+with this patch to jgm+@cmu.edu.
+
+RCPT streming avoids network round trips by sending all RCPT commands
+for a single SMTP transaction together.  Sendmail then waits for all
+the replies, matching them up with the apropriate addresses.
+
+Apply to the sendmail src directory (your line numbers may vary) and
+compile with -DRCPTSTREAM

+         XLA - Extended Load Average design for Sendmail R6
+         --------------------------------------------------
+
+          Christophe Wolfhugel - Herve Schauer Consultants

+
+
+WARNING:  this extension is supplied as a contribution to Sendmail.
+Should you have trouble, questions, please contact me directly, and
+*not* the Sendmail development team.
+
+
+ABSTRACT
+
+Sendmail currently furnishes a limitation mecanism which is based on
+the system load average, when available.  Experience has prooven that
+this was not sufficiant for some particular situations, for example
+if you have slow and/or overloaded links. This can easily cause both
+system and network congestions with Sendmail having to handle a large
+number of simultaneous sessions on the same overloaded link, causing
+most of the SMTP sessions to timeout after a long time.  The system
+load average is also generally too slow to react when your system
+gets a burst of incoming or outgoing SMTP sessions which on some
+stations can easily cause system unavailabilities.
+
+The extended load average module has been designed in order to furnish
+a way of limitation the load generated by Sendmail to both your
+system and your network. This design can be used either alone or as
+complementary to the system load average if your system supports it.
+
+Limitation is based on the number of incoming/outgoing SMTP sessions,
+and remote hosts are classified in classes. The system administrator
+will define a maximum number of incoming SMTP sessions as well as
+a maximum total (incoming + outgoing) sessions for each class of
+hosts. A class can be either an individual machine or a network.
+
+When the limit is reached for a given class, all incoming SMTP
+connections will be politely refused. When the limit is reached for
+all classes, the SMTP connections will be refused by the system
+(which one could consider as less politely :)).
+On outgoing mail, messages will be queued for delayed processing.
+
+The extended load average parameters are given in the Sendmail
+configuration file, and when not present, Sendmail behaves the
+usual way.
+
+
+COMPILATION
+
+Copy the xla.c module in the src sub-directory, edit the Makefile
+in order to define XLA (-DXLA). Also add the xla.[co] module name
+in the list of files so that it gets compiled.
+
+Regenerate sendmail by removing all objects, or at least those
+containing references to XLA (this list may vary, so use grep to
+get the module list).  This will generate a new sendmail executable
+containing the xla code.
+
+Debugging level 59 has been assigned to this module and when used
+it provides some output (sendmail -d59.x).  Please check the source
+code to see which levels are supported.
+
+
+CONFIGURATION
+
+The extended average uses a new set of configuration lines in the
+sendmail.cf file.  All newly introduced line begin with the letter L
+(capital L).
+
+Before detailling the syntax, first an example (this can be placed
+at any section of the sendmail.cf file, note that the order is
+important). Fields are separated by (one or more) tabs/spaces.
+
+# File name used to store the counters
+L/etc/sendmail.la
+# Classes definition
+# Lname            #queue #reject
+L*.insa-lyon.fr         8       3
+L*.univ-lyon1.fr        6       4
+L*                     15      16
+
+The first line defines the working file which will be used in order
+to have the occurences of Sendmail read and update the counters. The
+format of this file is described in the "Design" section.
+This line is mandatory and the specified file must be absolute (ie
+begin with a slash).
+
+Then you can specify one or more classes. The last class (*) is also
+mandatory and should be in last position as the first match will stop
+the search and if there is no match the behavior of Sendmail is unknown.
+
+Each class has three fields separated by one or more tabs/spaces.
+
+L{mask}         {queue_#}      {refuse_#}
+
+The {mask} is a simple mask. It can be either an explicit host name
+(like grasp.insa-lyon.fr) or a mask starting with "*." or just "*".
+No other variants are allowed.
+
+Lgrasp.insa-lyon.fr  will match exactely any session to/from this host.
+
+L*.insa-lyon.fr      will match any session to/from any machine in the
+                     insa-lyon.fr domain as well as from the machine
+                     named "insa-lyon.fr" if it exists.
+
+L*                   will match any session, and thus should also be
+                     last in the list to act as a catchup line.
+
+The {queue_#} is the maximum number of SMTP sessions in the given class
+for both incoming and outgoing messages. The {refuse_#} indicates when
+to refuse incoming messages for this class. The interaction between
+those counters is somewhat subtle. It seems logical that a standard
+configuration has {queue_#} >= {refuse_#}, and in fact in most
+configurations they can be equal (that's why what I use in my environment).
+Thus, this is not mandatory. If {queue_#} < {refuse_#} outgoing messages
+will be lower priority than incoming messages and once a class gets loaded
+the outgoing messages are blocked first.
+
+I use very low values in some situations, for example I have a customer
+connected to the Internet via a 9600 bps line, they also have internal
+users sending burst of messages (10, 20 small messages coming in just
+one or two seconds).  Both situations were unsupportable. The line is
+too slow to handle many simultaneous connections and the mail server
+does not have the ressources to handle such a heavy load (it's a 12 Megs
+Sun 3 also doing Usenet news).
+
+I have defined following section in the configuration file, and experience
+shows the benefits for everyone. Fake domain for the example: customer.fr.
+
+L/etc/sendmail.la
+L*.customer.fr          8       8
+L*                      3       3
+
+This means that there might not be more than 8 simultaneous SMTP sessions
+between the mail server and any other internal host. This is to protect
+the station from heavy loads like users (or applications !) sending
+several tenths of messages in just a few seconds).
+No more than 3 SMTP sessions are authorized with any other host, this is
+to save the load of the slow 9600 line to the Internet.
+
+Drawback is that is you have 3 * 2 Megs sessions established from/to the
+outside, all your mail will be held until one slot gets available, on
+a 9600 bps line just make your counts, il blocks your line during over
+one hour.
+
+
+DESIGN
+
+Sendmail will analyze the "L" lines in the configuration file during
+startup (or read the initialized structure from the frozen file).
+When started in daemon mode (and only there), any existing working file
+will be cleared and a new one is created. Each class gets a record in
+the sendmail.la work file. The size of this record is a short integer
+(generally two bytes) and represents the count of active sessions in
+the given class.  Read/Write operations in this file are done in
+one operation (as anyway the size is far below one disk sector). The
+file is locked with Sendmail's lockfile() function priori to any
+access.
+
+Handling incoming SMTP sessions.
+
+There is interaction is two points in the Sendmail source code. First
+on the listen system call: if all slots in all classes are in use,
+a listen(0) is done so that the system rejects any incoming SMTP session.
+This avois to fork and then reject the connexion.
+
+If there are some free slots, nothing better than accepting the
+connection, then forking can be done. The child process then checks if
+the adequate class is full or not. If full, it rejects the connection
+with a "421 Too many sessions" diagnostic to the sender (which should
+then appear when the remote users do a mailq). If the treshold {reject_#}
+is not reached, the connection is accepted and the counter is sendmail.la
+is updated.
+
+Handling outgoing SMTP sessions.
+
+As soon as Sendmail needs to connect to a distant host, the adequate class
+is checked against {queue_#} and if no slots are available, the message is
+queued for further processing.
+
+Sendmail's connection caching.
+
+Sendmail-R6 introduces a new design: connection caching, ie several SMTP
+sessions can be opened at the same time.  This could cause some problems
+when sending mail, as after having a few connections opened, all slots
+could be in use and generate a partial delivery of the message.  In
+order to deal with this, xla.c uses following design "for a given
+sendmail process, only the first connection in a given class is counted".
+This can be done because sendmail does not do parralel message sending
+on the different channels.
+
+End of connection.
+
+As soon as a connection is closed, the counters will be automatically
+updated.
+
+
+
+Please look at the code to understand of all this works. Comments,
+suggestions, questions welcome.

+ABSTRACT
+.sp \n(psu
+Routing mail through a heterogenous internet presents many new
+problems.  Among the worst of these is that of address mapping.
+Historically, this has been handled on an
+.i "ad hoc"
+basis.  However,
+this approach has become unmanageable as internets grow.
+.sp \n(psu
+Sendmail acts a unified "post office" to which all mail can be
+submitted.  Address interpretation is controlled by a production
+system, which can parse both domain-based addressing and old-style
+.i "ad hoc"
+addresses.
+The production system is powerful
+enough to rewrite addresses in the message header to conform to the
+standards of a number of common target networks, including old
+(NCP/RFC733) Arpanet, new (TCP/RFC822) Arpanet, UUCP, and Phonenet.
+Sendmail also implements an SMTP server, message
+queueing, and aliasing.

+\(dgA considerable part of this work
+was done while under the employ
+of the INGRES Project
+at the University of California at Berkeley
+and at Britton Lee.
+.)f
+.pp
+.i Sendmail
+implements a general internetwork mail routing facility,
+featuring aliasing and forwarding,
+automatic routing to network gateways,
+and flexible configuration.
+.pp
+In a simple network,
+each node has an address,
+and resources can be identified
+with a host-resource pair;
+in particular,
+the mail system can refer to users
+using a host-username pair.
+Host names and numbers have to be administered by a central authority,
+but usernames can be assigned locally to each host.
+.pp
+In an internet,
+multiple networks with different characterstics
+and managements
+must communicate.
+In particular,
+the syntax and semantics of resource identification change.
+Certain special cases can be handled trivially
+by
+.i "ad hoc"
+techniques,
+such as
+providing network names that appear local to hosts
+on other networks,
+as with the Ethernet at Xerox PARC.
+However,  the general case is extremely complex.
+For example,
+some networks require point-to-point routing,
+which simplifies the database update problem
+since only adjacent hosts must be entered
+into the system tables,
+while others use end-to-end addressing.
+Some networks use a left-associative syntax
+and others use a right-associative syntax,
+causing ambiguity in mixed addresses.
+.pp
+Internet standards seek to eliminate these problems.
+Initially, these proposed expanding the address pairs
+to address triples,
+consisting of
+{network, host, resource}
+triples.
+Network numbers must be universally agreed upon,
+and hosts can be assigned locally
+on each network.
+The user-level presentation was quickly expanded
+to address domains,
+comprised of a local resource identification
+and a hierarchical domain specification
+with a common static root.
+The domain technique
+separates the issue of physical versus logical addressing.
+For example,
+an address of the form
+.q "eric@a.cc.berkeley.arpa"
+describes only the logical
+organization of the address space.
+.pp
+.i Sendmail
+is intended to help bridge the gap
+between the totally
+.i "ad hoc"
+world
+of networks that know nothing of each other
+and the clean, tightly-coupled world
+of unique network numbers.
+It can accept old arbitrary address syntaxes,
+resolving ambiguities using heuristics
+specified by the system administrator,
+as well as domain-based addressing.
+It helps guide the conversion of message formats
+between disparate networks.
+In short,
+.i sendmail
+is designed to assist a graceful transition
+to consistent internetwork addressing schemes.
+.sp
+.pp
+Section 1 discusses the design goals for
+.i sendmail .
+Section 2 gives an overview of the basic functions of the system.
+In section 3,
+details of usage are discussed.
+Section 4 compares
+.i sendmail
+to other internet mail routers,
+and an evaluation of
+.i sendmail
+is given in section 5,
+including future plans.
+.sh 1 "DESIGN GOALS"
+.pp
+Design goals for
+.i sendmail
+include:
+.np
+Compatibility with the existing mail programs,
+including Bell version 6 mail,
+Bell version 7 mail
+[UNIX83],
+Berkeley
+.i Mail
+[Shoens79],
+BerkNet mail
+[Schmidt79],
+and hopefully UUCP mail
+[Nowitz78a, Nowitz78b].
+ARPANET mail
+[Crocker77a, Postel77]
+was also required.
+.np
+Reliability, in the sense of guaranteeing
+that every message is correctly delivered
+or at least brought to the attention of a human
+for correct disposal;
+no message should ever be completely lost.
+This goal was considered essential
+because of the emphasis on mail in our environment.
+It has turned out to be one of the hardest goals to satisfy,
+especially in the face of the many anomalous message formats
+produced by various ARPANET sites.
+For example,
+certain sites generate improperly formated addresses,
+occasionally
+causing error-message loops.
+Some hosts use blanks in names,
+causing problems with
+UNIX mail programs that assume that an address
+is one word.
+The semantics of some fields
+are interpreted slightly differently
+by different sites.
+In summary,
+the obscure features of the ARPANET mail protocol
+really
+.i are
+used and
+are difficult to support,
+but must be supported.
+.np
+Existing software to do actual delivery
+should be used whenever possible.
+This goal derives as much from political and practical considerations
+as technical.
+.np
+Easy expansion to
+fairly complex environments,
+including multiple
+connections to a single network type
+(such as with multiple UUCP or Ether nets
+[Metcalfe76]).
+This goal requires consideration of the contents of an address
+as well as its syntax
+in order to determine which gateway to use.
+For example,
+the ARPANET is bringing up the
+TCP protocol to replace the old NCP protocol.
+No host at Berkeley runs both TCP and NCP,
+so it is necessary to look at the ARPANET host name
+to determine whether to route mail to an NCP gateway
+or a TCP gateway.
+.np
+Configuration should not be compiled into the code.
+A single compiled program should be able to run as is at any site
+(barring such basic changes as the CPU type or the operating system).
+We have found this seemingly unimportant goal
+to be critical in real life.
+Besides the simple problems that occur when any program gets recompiled
+in a different environment,
+many sites like to
+.q fiddle
+with anything that they will be recompiling anyway.
+.np
+.i Sendmail
+must be able to let various groups maintain their own mailing lists,
+and let individuals specify their own forwarding,
+without modifying the system alias file.
+.np
+Each user should be able to specify which mailer to execute
+to process mail being delivered for him.
+This feature allows users who are using specialized mailers
+that use a different format to build their environment
+without changing the system,
+and facilitates specialized functions
+(such as returning an
+.q "I am on vacation"
+message).
+.np
+Network traffic should be minimized
+by batching addresses to a single host where possible,
+without assistance from the user.
+.pp
+These goals motivated the architecture illustrated in figure 1.

+Figure 1 \*- Sendmail System Structure.
+.hl
+.)z
+The user interacts with a mail generating and sending program.
+When the mail is created,
+the generator calls
+.i sendmail ,
+which routes the message to the correct mailer(s).
+Since some of the senders may be network servers
+and some of the mailers may be network clients,
+.i sendmail
+may be used as an internet mail gateway.
+.sh 1 "OVERVIEW"
+.sh 2 "System Organization"
+.pp
+.i Sendmail
+neither interfaces with the user
+nor does actual mail delivery.
+Rather,
+it collects a message
+generated by a user interface program (UIP)
+such as Berkeley
+.i Mail ,
+MS
+[Crocker77b],
+or MH
+[Borden79],
+edits the message as required by the destination network,
+and calls appropriate mailers
+to do mail delivery or queueing for network transmission\**.
+.(f
+\**except when mailing to a file,
+when
+.i sendmail
+does the delivery directly.
+.)f
+This discipline allows the insertion of new mailers
+at minimum cost.
+In this sense 
+.i sendmail
+resembles the Message Processing Module (MPM)
+of [Postel79b].
+.sh 2 "Interfaces to the Outside World"
+.pp
+There are three ways
+.i sendmail
+can communicate with the outside world,
+both in receiving and in sending mail.
+These are using the conventional UNIX
+argument vector/return status,
+speaking SMTP over a pair of UNIX pipes,
+and speaking SMTP over an interprocess(or) channel.
+.sh 3 "Argument vector/exit status"
+.pp
+This technique is the standard UNIX method
+for communicating with the process.
+A list of recipients is sent in the argument vector,
+and the message body is sent on the standard input.
+Anything that the mailer prints
+is simply collected and sent back to the sender
+if there were any problems.
+The exit status from the mailer is collected
+after the message is sent,
+and a diagnostic is printed if appropriate.
+.sh 3 "SMTP over pipes"
+.pp
+The SMTP protocol
+[Postel82]
+can be used to run an interactive lock-step interface
+with the mailer.
+A subprocess is still created,
+but no recipient addresses are passed to the mailer
+via the argument list.
+Instead, they are passed one at a time
+in commands sent to the processes standard input.
+Anything appearing on the standard output
+must be a reply code
+in a special format.
+.sh 3 "SMTP over an IPC connection"
+.pp
+This technique is similar to the previous technique,
+except that it uses a 4.2bsd IPC channel
+[UNIX83].
+This method is exceptionally flexible
+in that the mailer need not reside
+on the same machine.
+It is normally used to connect to a sendmail process
+on another machine.
+.sh 2 "Operational Description"
+.pp
+When a sender wants to send a message,
+it issues a request to
+.i sendmail
+using one of the three methods described above.
+.i Sendmail
+operates in two distinct phases.
+In the first phase,
+it collects and stores the message.
+In the second phase,
+message delivery occurs.
+If there were errors during processing
+during the second phase,
+.i sendmail
+creates and returns a new message describing the error
+and/or returns an status code
+telling what went wrong.
+.sh 3 "Argument processing and address parsing"
+.pp
+If
+.i sendmail
+is called using one of the two subprocess techniques,
+the arguments
+are first scanned
+and option specifications are processed.
+Recipient addresses are then collected,
+either from the command line
+or from the SMTP
+RCPT command,
+and a list of recipients is created.
+Aliases are expanded at this step,
+including mailing lists.
+As much validation as possible of the addresses
+is done at this step:
+syntax is checked, and local addresses are verified,
+but detailed checking of host names and addresses
+is deferred until delivery.
+Forwarding is also performed
+as the local addresses are verified.
+.pp
+.i Sendmail
+appends each address
+to the recipient list after parsing.
+When a name is aliased or forwarded,
+the old name is retained in the list,
+and a flag is set that tells the delivery phase
+to ignore this recipient.
+This list is kept free from duplicates,
+preventing alias loops
+and duplicate messages deliverd to the same recipient,
+as might occur if a person is in two groups.
+.sh 3 "Message collection"
+.pp
+.i Sendmail
+then collects the message.
+The message should have a header at the beginning.
+No formatting requirements are imposed on the message
+except that they must be lines of text
+(i.e., binary data is not allowed).
+The header is parsed and stored in memory,
+and the body of the message is saved
+in a temporary file.
+.pp
+To simplify the program interface,
+the message is collected even if no addresses were valid.
+The message will be returned with an error.
+.sh 3 "Message delivery"
+.pp
+For each unique mailer and host in the recipient list,
+.i sendmail
+calls the appropriate mailer.
+Each mailer invocation sends to all users receiving the message on one host.
+Mailers that only accept one recipient at a time
+are handled properly.
+.pp
+The message is sent to the mailer
+using one of the same three interfaces
+used to submit a message to sendmail.
+Each copy of the message is
+prepended by a customized header.
+The mailer status code is caught and checked,
+and a suitable error message given as appropriate.
+The exit code must conform to a system standard
+or a generic message
+(\c
+.q "Service unavailable" )
+is given.
+.sh 3 "Queueing for retransmission"
+.pp
+If the mailer returned an status that
+indicated that it might be able to handle the mail later,
+.i sendmail
+will queue the mail and try again later.
+.sh 3 "Return to sender"
+.pp
+If errors occur during processing,
+.i sendmail
+returns the message to the sender for retransmission.
+The letter can be mailed back
+or written in the file
+.q dead.letter
+in the sender's home directory\**.
+.(f
+\**Obviously, if the site giving the error is not the originating
+site, the only reasonable option is to mail back to the sender.
+Also, there are many more error disposition options,
+but they only effect the error message \*- the
+.q "return to sender"
+function is always handled in one of these two ways.
+.)f
+.sh 2 "Message Header Editing"
+.pp
+Certain editing of the message header
+occurs automatically.
+Header lines can be inserted
+under control of the configuration file.
+Some lines can be merged;
+for example,
+a
+.q From:
+line and a
+.q Full-name:
+line can be merged under certain circumstances.
+.sh 2 "Configuration File"
+.pp
+Almost all configuration information is read at runtime
+from an ASCII file,
+encoding
+macro definitions
+(defining the value of macros used internally),
+header declarations
+(telling sendmail the format of header lines that it will process specially,
+i.e., lines that it will add or reformat),
+mailer definitions
+(giving information such as the location and characteristics
+of each mailer),
+and address rewriting rules
+(a limited production system to rewrite addresses
+which is used to parse and rewrite the addresses).
+.pp
+To improve performance when reading the configuration file,
+a memory image can be provided.
+This provides a
+.q compiled
+form of the configuration file.
+.sh 1 "USAGE AND IMPLEMENTATION"
+.sh 2 "Arguments"
+.pp
+Arguments may be flags and addresses.
+Flags set various processing options.
+Following flag arguments,
+address arguments may be given,
+unless we are running in SMTP mode.
+Addresses follow the syntax in RFC822
+[Crocker82]
+for ARPANET
+address formats.
+In brief, the format is:
+.np
+Anything in parentheses is thrown away
+(as a comment).
+.np
+Anything in angle brackets (\c
+.q "<\|>" )
+is preferred
+over anything else.
+This rule implements the ARPANET standard that addresses of the form
+.(b
+user name <machine-address>
+.)b
+will send to the electronic
+.q machine-address
+rather than the human
+.q "user name."
+.np
+Double quotes
+(\ "\ )
+quote phrases;
+backslashes quote characters.
+Backslashes are more powerful
+in that they will cause otherwise equivalent phrases
+to compare differently \*- for example,
+.i user
+and
+.i
+"user"
+.r
+are equivalent,
+but
+.i \euser
+is different from either of them.
+.pp
+Parentheses, angle brackets, and double quotes
+must be properly balanced and nested.
+The rewriting rules control remaining parsing\**.
+.(f
+\**Disclaimer: Some special processing is done
+after rewriting local names; see below.
+.)f
+.sh 2 "Mail to Files and Programs"
+.pp
+Files and programs are legitimate message recipients.
+Files provide archival storage of messages,
+useful for project administration and history.
+Programs are useful as recipients in a variety of situations,
+for example,
+to maintain a public repository of systems messages
+(such as the Berkeley
+.i msgs
+program,
+or the MARS system
+[Sattley78]).
+.pp
+Any address passing through the initial parsing algorithm
+as a local address
+(i.e, not appearing to be a valid address for another mailer)
+is scanned for two special cases.
+If prefixed by a vertical bar (\c
+.q \^|\^ )
+the rest of the address is processed as a shell command.
+If the user name begins with a slash mark (\c
+.q /\^ )
+the name is used as a file name,
+instead of a login name.
+.pp
+Files that have setuid or setgid bits set
+but no execute bits set
+have those bits honored if
+.i sendmail
+is running as root.
+.sh 2 "Aliasing, Forwarding, Inclusion"
+.pp
+.i Sendmail
+reroutes mail three ways.
+Aliasing applies system wide.
+Forwarding allows each user to reroute incoming mail
+destined for that account.
+Inclusion directs
+.i sendmail
+to read a file for a list of addresses,
+and is normally used
+in conjunction with aliasing.
+.sh 3 "Aliasing"
+.pp
+Aliasing maps names to address lists using a system-wide file.
+This file is indexed to speed access.
+Only names that parse as local
+are allowed as aliases;
+this guarantees a unique key
+(since there are no nicknames for the local host).
+.sh 3 "Forwarding"
+.pp
+After aliasing,
+recipients that are local and valid
+are checked for the existence of a
+.q .forward
+file in their home directory.
+If it exists,
+the message is
+.i not
+sent to that user,
+but rather to the list of users in that file.
+Often
+this list will contain only one address,
+and the feature will be used for network mail forwarding.
+.pp
+Forwarding also permits a user to specify a private incoming mailer.
+For example,
+forwarding to:
+.(b
+"\^|\|/usr/local/newmail myname"
+.)b
+will use a different incoming mailer.
+.sh 3 "Inclusion"
+.pp
+Inclusion is specified in RFC 733 [Crocker77a] syntax:
+.(b
+:Include: pathname
+.)b
+An address of this form reads the file specified by
+.i pathname
+and sends to all users listed in that file.
+.pp
+The intent is
+.i not
+to support direct use of this feature,
+but rather to use this as a subset of aliasing.
+For example,
+an alias of the form:
+.(b
+project: :include:/usr/project/userlist
+.)b
+is a method of letting a project maintain a mailing list
+without interaction with the system administration,
+even if the alias file is protected.
+.pp
+It is not necessary to rebuild the index on the alias database
+when a :include: list is changed.
+.sh 2 "Message Collection"
+.pp
+Once all recipient addresses are parsed and verified,
+the message is collected.
+The message comes in two parts:
+a message header and a message body,
+separated by a blank line.
+.pp
+The header is formatted as a series of lines
+of the form
+.(b
+       field-name: field-value
+.)b
+Field-value can be split across lines by starting the following
+lines with a space or a tab.
+Some header fields have special internal meaning,
+and have appropriate special processing.
+Other headers are simply passed through.
+Some header fields may be added automatically,
+such as time stamps.
+.pp
+The body is a series of text lines.
+It is completely uninterpreted and untouched,
+except that lines beginning with a dot
+have the dot doubled
+when transmitted over an SMTP channel.
+This extra dot is stripped by the receiver.
+.sh 2 "Message Delivery"
+.pp
+The send queue is ordered by receiving host
+before transmission
+to implement message batching.
+Each address is marked as it is sent
+so rescanning the list is safe.
+An argument list is built as the scan proceeds.
+Mail to files is detected during the scan of the send list.
+The interface to the mailer
+is performed using one of the techniques
+described in section 2.2.
+.pp
+After a connection is established,
+.i sendmail
+makes the per-mailer changes to the header
+and sends the result to the mailer.
+If any mail is rejected by the mailer,
+a flag is set to invoke the return-to-sender function
+after all delivery completes.
+.sh 2 "Queued Messages"
+.pp
+If the mailer returns a
+.q "temporary failure"
+exit status,
+the message is queued.
+A control file is used to describe the recipients to be sent to
+and various other parameters.
+This control file is formatted as a series of lines,
+each describing a sender,
+a recipient,
+the time of submission,
+or some other salient parameter of the message.
+The header of the message is stored
+in the control file,
+so that the associated data file in the queue
+is just the temporary file that was originally collected.
+.sh 2 "Configuration"
+.pp
+Configuration is controlled primarily by a configuration file
+read at startup.
+.i Sendmail
+should not need to be recomplied except
+.np
+To change operating systems
+(V6, V7/32V, 4BSD).
+.np
+To remove or insert the DBM
+(UNIX database)
+library.
+.np
+To change ARPANET reply codes.
+.np
+To add headers fields requiring special processing.
+.lp
+Adding mailers or changing parsing
+(i.e., rewriting)
+or routing information
+does not require recompilation.
+.pp
+If the mail is being sent by a local user,
+and the file
+.q .mailcf
+exists in the sender's home directory,
+that file is read as a configuration file
+after the system configuration file.
+The primary use of this feature is to add header lines.
+.pp
+The configuration file encodes macro definitions,
+header definitions,
+mailer definitions,
+rewriting rules,
+and options.
+.sh 3 Macros
+.pp
+Macros can be used in three ways.
+Certain macros transmit
+unstructured textual information
+into the mail system,
+such as the name
+.i sendmail
+will use to identify itself in error messages.
+Other macros transmit information from
+.i sendmail
+to the configuration file
+for use in creating other fields
+(such as argument vectors to mailers);
+e.g., the name of the sender,
+and the host and user
+of the recipient.
+Other macros are unused internally,
+and can be used as shorthand in the configuration file.
+.sh 3 "Header declarations"
+.pp
+Header declarations inform
+.i sendmail
+of the format of known header lines.
+Knowledge of a few header lines
+is built into
+.i sendmail ,
+such as the
+.q From:
+and
+.q Date:
+lines.
+.pp
+Most configured headers
+will be automatically inserted
+in the outgoing message
+if they don't exist in the incoming message.
+Certain headers are suppressed by some mailers.
+.sh 3 "Mailer declarations"
+.pp
+Mailer declarations tell
+.i sendmail
+of the various mailers available to it.
+The definition specifies the internal name of the mailer,
+the pathname of the program to call,
+some flags associated with the mailer,
+and an argument vector to be used on the call;
+this vector is macro-expanded before use.
+.sh 3 "Address rewriting rules"
+.pp
+The heart of address parsing in
+.i sendmail
+is a set of rewriting rules.
+These are an ordered list of pattern-replacement rules,
+(somewhat like a production system,
+except that order is critical),
+which are applied to each address.
+The address is rewritten textually until it is either rewritten
+into a special canonical form
+(i.e.,
+a (mailer, host, user)
+3-tuple,
+such as {arpanet, usc-isif, postel}
+representing the address
+.q "postel@usc-isif" ),
+or it falls off the end.
+When a pattern matches,
+the rule is reapplied until it fails.
+.pp
+The configuration file also supports the editing of addresses
+into different formats.
+For example,
+an address of the form:
+.(b
+ucsfcgl!tef
+.)b
+might be mapped into:
+.(b
+tef@ucsfcgl.UUCP
+.)b
+to conform to the domain syntax.
+Translations can also be done in the other direction.
+.sh 3 "Option setting"
+.pp
+There are several options that can be set
+from the configuration file.
+These include the pathnames of various support files,
+timeouts,
+default modes,
+etc.
+.sh 1 "COMPARISON WITH OTHER MAILERS"
+.sh 2 "Delivermail"
+.pp
+.i Sendmail
+is an outgrowth of
+.i delivermail .
+The primary differences are:
+.np
+Configuration information is not compiled in.
+This change simplifies many of the problems
+of moving to other machines.
+It also allows easy debugging of new mailers.
+.np
+Address parsing is more flexible.
+For example,
+.i delivermail
+only supported one gateway to any network,
+whereas
+.i sendmail
+can be sensitive to host names
+and reroute to different gateways.
+.np
+Forwarding and
+:include:
+features eliminate the requirement that the system alias file
+be writable by any user
+(or that an update program be written,
+or that the system administration make all changes).
+.np
+.i Sendmail
+supports message batching across networks
+when a message is being sent to multiple recipients.
+.np
+A mail queue is provided in
+.i sendmail.
+Mail that cannot be delivered immediately
+but can potentially be delivered later
+is stored in this queue for a later retry.
+The queue also provides a buffer against system crashes;
+after the message has been collected
+it may be reliably redelivered
+even if the system crashes during the initial delivery.
+.np
+.i Sendmail
+uses the networking support provided by 4.2BSD
+to provide a direct interface networks such as the ARPANET
+and/or Ethernet
+using SMTP (the Simple Mail Transfer Protocol)
+over a TCP/IP connection.
+.sh 2 "MMDF"
+.pp
+MMDF
+[Crocker79]
+spans a wider problem set than
+.i sendmail .
+For example,
+the domain of
+MMDF includes a
+.q "phone network"
+mailer, whereas
+.i sendmail
+calls on preexisting mailers in most cases.
+.pp
+MMDF and
+.i sendmail
+both support aliasing,
+customized mailers,
+message batching,
+automatic forwarding to gateways,
+queueing,
+and retransmission.
+MMDF supports two-stage timeout,
+which
+.i sendmail
+does not support.
+.pp
+The configuration for MMDF
+is compiled into the code\**.
+.(f
+\**Dynamic configuration tables are currently being considered
+for MMDF;
+allowing the installer to select either compiled
+or dynamic tables.
+.)f
+.pp
+Since MMDF does not consider backwards compatibility
+as a design goal,
+the address parsing is simpler but much less flexible.
+.pp
+It is somewhat harder to integrate a new channel\**
+.(f
+\**The MMDF equivalent of a
+.i sendmail
+.q mailer.
+.)f
+into MMDF.
+In particular,
+MMDF must know the location and format
+of host tables for all channels,
+and the channel must speak a special protocol.
+This allows MMDF to do additional verification
+(such as verifying host names)
+at submission time.
+.pp
+MMDF strictly separates the submission and delivery phases.
+Although
+.i sendmail
+has the concept of each of these stages,
+they are integrated into one program,
+whereas in MMDF they are split into two programs.
+.sh 2 "Message Processing Module"
+.pp
+The Message Processing Module (MPM)
+discussed by Postel [Postel79b]
+matches
+.i sendmail
+closely in terms of its basic architecture.
+However,
+like MMDF,
+the MPM includes the network interface software
+as part of its domain.
+.pp
+MPM also postulates a duplex channel to the receiver,
+as does MMDF,
+thus allowing simpler handling of errors
+by the mailer
+than is possible in
+.i sendmail .
+When a message queued by
+.i sendmail
+is sent,
+any errors must be returned to the sender
+by the mailer itself.
+Both MPM and MMDF mailers
+can return an immediate error response,
+and a single error processor can create an appropriate response.
+.pp
+MPM prefers passing the message as a structured object,
+with type-length-value tuples\**.
+.(f
+\**This is similar to the NBS standard.
+.)f
+Such a convention requires a much higher degree of cooperation
+between mailers than is required by
+.i sendmail .
+MPM also assumes a universally agreed upon internet name space
+(with each address in the form of a net-host-user tuple),
+which
+.i sendmail
+does not.
+.sh 1 "EVALUATIONS AND FUTURE PLANS"
+.pp
+.i Sendmail
+is designed to work in a nonhomogeneous environment.
+Every attempt is made to avoid imposing unnecessary constraints
+on the underlying mailers.
+This goal has driven much of the design.
+One of the major problems
+has been the lack of a uniform address space,
+as postulated in [Postel79a]
+and [Postel79b].
+.pp
+A nonuniform address space implies that a path will be specified
+in all addresses,
+either explicitly (as part of the address)
+or implicitly
+(as with implied forwarding to gateways).
+This restriction has the unpleasant effect of making replying to messages
+exceedingly difficult,
+since there is no one
+.q address
+for any person,
+but only a way to get there from wherever you are.
+.pp
+Interfacing to mail programs
+that were not initially intended to be applied
+in an internet environment
+has been amazingly successful,
+and has reduced the job to a manageable task.
+.pp
+.i Sendmail
+has knowledge of a few difficult environments
+built in.
+It generates ARPANET FTP/SMTP compatible error messages
+(prepended with three-digit numbers
+[Neigus73, Postel74, Postel82])
+as necessary,
+optionally generates UNIX-style
+.q From
+lines on the front of messages for some mailers,
+and knows how to parse the same lines on input.
+Also,
+error handling has an option customized for BerkNet.
+.pp
+The decision to avoid doing any type of delivery where possible
+(even, or perhaps especially, local delivery)
+has turned out to be a good idea.
+Even with local delivery,
+there are issues of the location of the mailbox,
+the format of the mailbox,
+the locking protocol used,
+etc.,
+that are best decided by other programs.
+One surprisingly major annoyance in many internet mailers
+is that the location and format of local mail is built in.
+The feeling seems to be that local mail is so common
+that it should be efficient.
+This feeling is not born out by
+our experience;
+on the contrary,
+the location and format of mailboxes seems to vary widely
+from system to system.
+.pp
+The ability to automatically generate a response to incoming mail
+(by forwarding mail to a program)
+seems useful
+(\c
+.q "I am on vacation until late August...." )
+but can create problems
+such as forwarding loops
+(two people on vacation whose programs send notes back and forth,
+for instance)
+if these programs are not well written.
+A program could be written to do standard tasks correctly,
+but this would solve the general case.
+.pp
+It might be desirable to implement some form of load limiting.
+I am unaware of any mail system that addresses this problem,
+nor am I aware of any reasonable solution at this time.
+.pp
+The configuration file is currently practically inscrutable;
+considerable convenience could be realized
+with a higher-level format.
+.pp
+It seems clear that common protocols will be changing soon
+to accommodate changing requirements and environments.
+These changes will include modifications to the message header
+(e.g., [NBS80])
+or to the body of the message itself
+(such as for multimedia messages
+[Postel80]).
+Experience indicates that
+these changes should be relatively trivial to integrate
+into the existing system.
+.pp
+In tightly coupled environments,
+it would be nice to have a name server
+such as Grapvine
+[Birrell82]
+integrated into the mail system.
+This would allow a site such as
+.q Berkeley
+to appear as a single host,
+rather than as a collection of hosts,
+and would allow people to move transparently among machines
+without having to change their addresses.
+Such a facility
+would require an automatically updated database
+and some method of resolving conflicts.
+Ideally this would be effective even without
+all hosts being under
+a single management.
+However,
+it is not clear whether this feature
+should be integrated into the
+aliasing facility
+or should be considered a
+.q "value added"
+feature outside
+.i sendmail
+itself.
+.pp
+As a more interesting case,
+the CSNET name server
+[Solomon81]
+provides an facility that goes beyond a single
+tightly-coupled environment.
+Such a facility would normally exist outside of
+.i sendmail
+however.
+.sh 0 "ACKNOWLEDGEMENTS"
+.pp
+Thanks are due to Kurt Shoens for his continual cheerful
+assistance and good advice,
+Bill Joy for pointing me in the correct direction
+(over and over),
+and Mark Horton for more advice,
+prodding,
+and many of the good ideas.
+Kurt and Eric Schmidt are to be credited
+for using
+.i delivermail
+as a server for their programs
+(\c
+.i Mail
+and BerkNet respectively)
+before any sane person should have,
+and making the necessary modifications
+promptly and happily.
+Eric gave me considerable advice about the perils
+of network software which saved me an unknown
+amount of work and grief.
+Mark did the original implementation of the DBM version
+of aliasing, installed the VFORK code,
+wrote the current version of
+.i rmail ,
+and was the person who really convinced me
+to put the work into
+.i delivermail
+to turn it into
+.i sendmail .
+Kurt deserves accolades for using
+.i sendmail
+when I was myself afraid to take the risk;
+how a person can continue to be so enthusiastic
+in the face of so much bitter reality is beyond me.
+.pp
+Kurt,
+Mark,
+Kirk McKusick,
+Marvin Solomon,
+and many others have reviewed this paper,
+giving considerable useful advice.
+.pp
+Special thanks are reserved for Mike Stonebraker at Berkeley
+and Bob Epstein at Britton-Lee,
+who both knowingly allowed me to put so much work into this
+project
+when there were so many other things I really should
+have been working on.

+For Sendmail Version 8.1
+.)l
+.sp 2
+.pp
+.i Sendmail
+implements a general purpose internetwork mail routing facility
+under the UNIX*
+.(f
+*UNIX is a trademark of Bell Laboratories.
+.)f
+operating system.
+It is not tied to any one transport protocol \*-
+its function may be likened to a crossbar switch,
+relaying messages from one domain into another.
+In the process,
+it can do a limited amount of message header editing
+to put the message into a format that is appropriate
+for the receiving domain.
+All of this is done under the control of a configuration file.
+.pp
+Due to the requirements of flexibility
+for
+.i sendmail ,
+the configuration file can seem somewhat unapproachable.
+However, there are only a few basic configurations
+for most sites,
+for which standard configuration files have been supplied.
+Most other configurations
+can be built by adjusting an existing configuration files
+incrementally.
+.pp
+.i Sendmail
+is based on
+RFC822 (Internet Mail Format Protocol),
+RFC821 (Simple Mail Transport Protocol),
+RFC1123 (Internet Host Requirements),
+and
+RFC1425 (SMTP Service Extensions).
+However, since
+.i sendmail
+is designed to work in a wider world,
+in many cases it can be configured to exceed these protocols.
+These cases are described herein.
+.pp
+Although
+.i sendmail
+is intended to run
+without the need for monitoring,
+it has a number of features
+that may be used to monitor or adjust the operation
+under unusual circumstances.
+These features are described.
+.pp
+Section one describes how to do a basic
+.i sendmail
+installation.
+Section two
+explains the day-to-day information you should know
+to maintain your mail system.
+If you have a relatively normal site,
+these two sections should contain sufficient information
+for you to install
+.i sendmail
+and keep it happy.
+Section three
+describes some parameters that may be safely tweaked.
+Section four
+has information regarding the command line arguments.
+Section five
+contains the nitty-gritty information about the configuration
+file.
+This section is for masochists
+and people who must write their own configuration file.
+Section six
+gives a brief description of differences
+in this version of
+.i sendmail .
+The appendixes give a brief
+but detailed explanation of a number of features
+not described in the rest of the paper.
+.bp 5
+.sh 1 "BASIC INSTALLATION"
+.pp
+.i
+This section is a very rough rewrite;
+please don't assume that it is already completely correct.
+However,
+please send me suggestions so that later versions of this document
+can be more accurate.
+.pp
+There are two basic steps to installing sendmail.
+The hard part is to build the configuration table.
+This is a file that sendmail reads when it starts up
+that describes the mailers it knows about,
+how to parse addresses,
+how to rewrite the message header,
+and the settings of various options.
+Although the configuration table is quite complex,
+a configuration can usually be built
+by adjusting an existing off-the-shelf configuration.
+The second part is actually doing the installation,
+i.e., creating the necessary files, etc.
+.pp
+The remainder of this section will describe the installation of sendmail
+assuming you can use one of the existing configurations
+and that the standard installation parameters are acceptable.
+All pathnames and examples
+are given from the root of the
+.i sendmail
+subtree,
+normally
+.i /usr/src/usr.\*(SD/sendmail
+on 4.3BSD.
+.pp
+If you are loading this off the tape,
+continue with the next session.
+If you have a running binary already on your system,
+you should probably skip to section 1.2.
+.sh 2 "Compiling Sendmail"
+.pp
+All sendmail source is in the
+.i src
+subdirectory.
+If you are running on a 4.4BSD system,
+compile by typing
+.q make .
+On other systems, you may have to make some other adjustments.
+.sh 3 "Old versions of make"
+.pp
+If you are not running the new version of
+.b make
+you will probably have to use
+.(b
+make \-f Makefile.dist
+.)b
+This file does not assume several new syntaxes,
+including the
+.q +=
+syntax in macro definition
+and the
+.q ".include"
+syntax.
+.sh 3 "Compilation flags"
+.pp
+.i Sendmail
+supports two different formats
+for the
+.i aliases
+database.
+These formats are:
+.nr ii 1i
+.ip NDBM
+The ``new DBM'' format,
+available on nearly all systems around today.
+This was the preferred format prior to 4.4BSD.
+It allows such complex things as multiple databases
+and closing a currently open database.
+.ip NEWDB
+The new database package from Berkeley.
+If you have this, use it.
+It allows
+long records,
+multiple open databases,
+real in-memory caching,
+and so forth.
+You can define this in conjunction with one of the other two;
+if you do,
+old databases are read,
+but when a new database is created it will be in NEWDB format.
+As a nasty hack,
+if you have NEWDB, NDBM, and YPCOMPAT defined,
+and if the file
+.i /var/yp/Makefile
+exists and is readable,
+.i sendmail
+will create both new and old versions of the alias file
+during a
+.i newalias
+command.
+This is required because the Sun NIS/YP system
+reads the DBM version of the alias file.
+It's ugly as sin,
+but it works.
+.lp
+If neither of these are defined,
+.i sendmail
+reads the alias file into memory on every invocation.
+This can be slow and should be avoided.
+.pp
+System V based systems can define
+SYSTEM5
+to make several small adjustments.
+This changes the handling of timezones
+and uses the much less efficient
+.i lockf
+call in preference to
+.i flock .
+These can be specified separately using the compilation flags
+SYS5TZ
+and
+LOCKF
+respectively.
+.pp
+If you don't have the
+.i unsetenv
+routine in your system library, define the UNSETENV compilation flag.
+.pp
+You may also have to define the compilation variable LA_TYPE
+to describe how your load average is computed.
+This and other flags are detailed in section 6.1.
+.sh 3 "Compilation and installation"
+.pp
+After making the local system configuration described above,
+You should be able to compile and install the system.
+Compilation can be performed using
+.q make\**
+.(f
+\**where you may have to replace
+.q make
+with
+.q "make \-f Makefile.dist"
+as appropriate.
+.)f
+in the
+.b sendmail/src
+directory.
+You may be able to install using
+.(b
+make install
+.)b
+This should install the binary in
+/usr/\*(SD
+and create links from
+/usr/bin/newaliases
+and
+/usr/bin/mailq
+to
+/usr/\*(SD/sendmail.
+On BSD4.4 systems it will also format and install man pages.
+.sh 2 "Configuration Files"
+.pp
+.i Sendmail
+cannot operate without a configuration file.
+The configuration defines the mail systems understood at this site,
+how to access them,
+how to forward email to remote mail systems,
+and a number of tuning parameters.
+This configuration file is detailed
+in the later portion of this document.
+.pp
+The
+.i sendmail
+configuration can be daunting at first.
+The world is complex,
+and the mail configuration reflects that.
+The distribution includes an m4-based configuration package
+that hides a lot of the complexity.
+.pp
+These configuration files are simpler than old versions
+largely because the world has become simpler;
+in particular,
+text-based host files are officially eliminated,
+obviating the need to
+.q hide
+hosts behind a registered internet gateway.
+.pp
+These files also assume that most of your neighbors
+use domain-based UUCP addressing;
+that is,
+instead of naming hosts as
+.q host!user
+they will use
+.q host.domain!user .
+The configuration files can be customized to work around this,
+but it is more complex.
+.pp
+I haven't tested these yet on an isolated LAN environment
+with a single UUCP connection to the outside world.
+If you are in such an environment,
+please send comments to
+sendmail@okeeffe.CS.Berkeley.EDU.
+.pp
+Our configuration files are processed by
+.i m4
+to facilitate local customization;
+the directory
+.i cf
+of the
+sendmail
+distribution directory
+contains the source files.
+This directory contains several subdirectories:
+.nr ii 1i
+.ip cf
+Both site-dependent and site-independent descriptions of hosts.
+These can be literal host names
+(e.g.,
+.q ucbvax.mc )
+when the hosts are gateways
+or more general descriptions
+(such as
+.q "tcpproto.mc"
+as a general description of an SMTP-connected host
+or
+.q "uucpproto.mc"
+as a general description of a UUCP-connected host).
+Files ending
+.b \&.mc
+(``Master Configuration'')
+are the input descriptions;
+the output is in the corresponding
+.b \&.cf
+file.
+The general structure of these files is described below.
+.ip domain
+Site-dependent subdomain descriptions.
+These are tied to the way your organization wants to do addressing.
+For example,
+.b domain/cs.exposed.m4
+is our description for hosts in the CS.Berkeley.EDU subdomain
+that want their individual hostname to be externally visible;
+.b domain/cs.hidden.m4
+is the same except that the hostname is hidden
+(everything looks like it comes from CS.Berkeley.EDU).
+These are referenced using the
+.sm DOMAIN
+.b m4
+macro in the
+.b \&.mc
+file.
+.ip feature
+Definitions of specific features that some particular host in your site
+might want.
+These are referenced using the
+.sm FEATURE
+.b m4
+macro.
+An example feature is
+use_cw_file
+(which tells sendmail to read an /etc/sendmail.cw file on startup
+to find the set of local names).
+.ip hack
+Local hacks, referenced using the
+.sm HACK
+.b m4
+macro.
+Try to avoid these.
+The point of having them here is to make it clear that they smell.
+.ip m4
+Site-independent
+.i m4 (1)
+include files that have information common to all configuration files.
+This can be thought of as a
+.q #include
+directory.
+.ip mailer
+Definitions of mailers,
+referenced using the
+.sm MAILER
+.b m4
+macro.
+Defined mailer types in this distribution are
+fax,
+local,
+smtp,
+uucp,
+and usenet.
+.ip ostype
+Definitions describing various operating system environments
+(such as the location of support files).
+These are referenced using the
+.sm OSTYPE
+.b m4
+macro.
+.ip sh
+Shell files used by the
+.b m4
+build process.
+You shouldn't have to mess with these.
+.ip siteconfig
+Local site configuration information,
+such as UUCP connectivity.
+They normally contain lists of site information, for example:
+.(b
+SITE(contessa)
+SITE(hoptoad)
+SITE(nkainc)
+SITE(well)
+.)b
+They are referenced using the SITECONFIG macro:
+.(b
+SITECONFIG(site.config.file, name_of_site, X)
+.)b
+where
+.i X
+is the macro/class name to use.
+It can be U
+(indicating locally connected hosts)
+or one of W, X, or Y
+for up to three remote UUCP hubs.
+.pp
+If you are in a new domain
+(e.g., a company),
+you will probably want to create a
+cf/domain
+file for your domain.
+This consists primarily of relay definitions:
+for example, Berkeley's domain definition
+defines relays for
+BitNET,
+CSNET,
+and UUCP.
+Of these,
+only the UUCP relay is particularly specific
+to Berkeley.
+All of these are internet-style domain names.
+Please check to make certain they are reasonable for your domain.
+.pp
+Subdomains at Berkeley are also represented in the
+cf/domain
+directory.
+For example,
+the domain
+cs-exposed
+is the Computer Science subdomain with the local hostname shown
+to other users;
+cs-hidden
+makes users appear to be from the CS.Berkeley.EDU subdomain
+(with no local host information included).
+You will probably have to update this directory
+to be appropriate for your domain.
+.pp
+You will have to use or create
+.b \&.mc
+files in the
+.i cf/cf
+subdirectory for your hosts.
+This is detailed in the
+cf/README
+file.
+.sh 2 "Details of Installation Files"
+.pp
+This subsection describes the files that
+comprise the
+sendmail
+installation.
+.sh 3 "/usr/\*(SD/sendmail"
+.pp
+The binary for sendmail is located in /usr/\*(SD\**.
+.(f
+\**This is usually
+/usr/sbin
+on 4.4BSD and newer systems;
+many systems install it in
+/usr/lib.
+I understand it is in /usr/ucblib
+on System V Release 4.
+.)f
+It should be setuid root.
+For security reasons,
+/, /usr, and /usr/\*(SD
+should be owned by root, mode 755\**.
+.(f
+\**Some vendors ship them owned by bin;
+this creates a security hole that is not actually related to
+.i sendmail .
+Other important directories that should have restrictive ownerships
+and permissions are
+/bin, /usr/bin, /etc, /usr/etc, /lib, and /usr/lib.
+.)f
+.sh 3 "/etc/sendmail.cf"
+.pp
+This is the configuration file for sendmail.
+This and the frozen configuration file
+are the only two non-library file names compiled into sendmail\**.
+.(f
+\**The system libraries can reference other files;
+in particular, system library subroutines that
+sendmail
+calls probably reference
+.i /etc/passwd
+and
+.i /etc/resolv.conf .
+.)f
+Some older systems install it in
+.b /usr/lib/sendmail.cf .
+.pp
+If you want to move this file,
+change
+.i src/pathnames.h .
+.pp
+The configuration file is normally created
+using the distribution files described above.
+If you have a particularly unusual system configuration
+you may need to create a special version.
+The format of this file is detailed in later sections
+of this document.
+.sh 3 "/usr/ucb/newaliases"
+.pp
+If you are running delivermail,
+it is critical that the
+.i newaliases
+command be replaced.
+This can just be a link to
+.i sendmail :
+.(b
+rm \-f /usr/ucb/newaliases
+ln /usr/\*(SD/sendmail /usr/ucb/newaliases
+.)b
+This can be installed in whatever search path you prefer
+for your system.
+.sh 3 "/var/spool/mqueue"
+.pp
+The directory
+.i /var/spool/mqueue
+should be created to hold the mail queue.
+This directory should be mode 700
+and owned by root.
+.pp
+The actual path of this directory
+is defined in the
+.b Q
+option of the
+.i sendmail.cf
+file.
+.sh 3 "/etc/aliases*"
+.pp
+The system aliases are held in
+.q /etc/aliases .
+A sample is given in
+.q lib/aliases
+which includes some aliases which
+.i must
+be defined:
+.(b
+cp lib/aliases /etc/aliases
+.i "edit /etc/aliases"
+.)b
+You should extend this file with any aliases that are apropos to your system.
+.pp
+Normally
+.i sendmail
+looks at a version of these files maintained by the
+.i dbm \|(3)
+or
+.i db \|(3)
+routines.
+These are stored either in
+.q /etc/aliases.dir
+and
+.q /etc/aliases.pag
+or
+.q /etc/aliases.db
+depending on which database package you are using.
+These can initially be created as empty files,
+but they will have to be initialized promptly.
+These should be mode 644:
+.(b
+cp /dev/null /etc/aliases.dir
+cp /dev/null /etc/aliases.pag
+chmod 644 /etc/aliases.*
+newaliases
+.)b
+The
+.i db
+routines preset the mode reasonably,
+so this step can be skipped.
+The actual path of this file
+is defined in the
+.b A
+option of the
+.i sendmail.cf
+file.
+.sh 3 "/etc/sendmail.fc"
+.pp
+If you intend to install the frozen version of the configuration file
+(for quick startup)
+you should create the file /etc/sendmail.fc
+and initialize it.
+This step may be safely skipped.
+.(b
+cp /dev/null /etc/sendmail.fc
+chmod 644 /etc/sendmail.fc
+/usr/\*(SD/sendmail \-bz
+.)b
+In general, freeze files are not worth doing
+unless your disks are much faster than your CPU;
+this is seldom true any more.
+.pp
+If your
+.i sendmail
+was not compiled with
+.sm FROZENCONFIG
+defined, the
+.b \-bz
+flag will be ignored.
+.sh 3 "/etc/rc"
+.pp
+It will be necessary to start up the sendmail daemon when your system reboots.
+This daemon performs two functions:
+it listens on the SMTP socket for connections
+(to receive mail from a remote system)
+and it processes the queue periodically
+to insure that mail gets delivered when hosts come up.
+.pp
+Add the following lines to
+.q /etc/rc
+(or
+.q /etc/rc.local
+as appropriate)
+in the area where it is starting up the daemons:
+.(b
+if [ \-f /usr/\*(SD/sendmail \-a \-f /etc/sendmail.cf ]; then
+       (cd /var/spool/mqueue; rm \-f [lnx]f*)
+       /usr/\*(SD/sendmail \-bd \-q30m &
+       echo \-n ' sendmail' >/dev/console
+fi
+.)b
+The
+.q cd
+and
+.q rm
+commands insure that all lock files have been removed;
+extraneous lock files may be left around
+if the system goes down in the middle of processing a message.
+The line that actually invokes
+.i sendmail
+has two flags:
+.q \-bd
+causes it to listen on the SMTP port,
+and
+.q \-q30m
+causes it to run the queue every half hour.
+.pp
+Some people use a more complex startup script,
+removing zero length qf files and df files for which there is no qf file.
+For example:
+.(b
+# remove zero length qf files
+for qffile in qf*
+do
+       if [ \-r $qffile ]
+       then
+               if [ ! \-s $qffile ]
+               then
+                       echo \-n " <zero: $qffile>" > /dev/console
+                       rm \-f $qffile
+               fi
+       fi
+done
+# rename tf files to be qf if the qf does not exist
+for tffile in tf*
+do
+       qffile=`echo $tffile | sed 's/t/q/'`
+       if [ \-r $tffile \-a ! \-f $qffile ]
+       then
+               echo \-n " <recovering: $tffile>" > /dev/console
+               mv $tffile $qffile
+       else
+               echo \-n " <extra: $tffile>" > /dev/console
+               rm \-f $tffile
+       fi
+done
+# remove bogus qf files
+for dffile in df*
+do
+       qffile=`echo $dffile | sed 's/d/q/'`
+       if [ \-r $dffile \-a ! \-f $qffile ]
+       then
+               echo \-n " <incomplete: $dffile>" > /dev/console
+               rm \-f $dffile
+       fi
+done
+fi
+.)b
+.pp
+If you are not running a version of UNIX
+that supports Berkeley TCP/IP,
+do not include the
+.b \-bd
+flag.
+.sh 3 "/usr/lib/sendmail.hf"
+.pp
+This is the help file used by the SMTP
+.b HELP
+command.
+It should be copied from
+.q lib/sendmail.hf :
+.(b
+cp lib/sendmail.hf /usr/lib
+.)b
+The actual path of this file
+is defined in the
+.b H
+option of the
+.i sendmail.cf
+file.
+.sh 3 "/etc/sendmail.st"
+.pp
+If you wish to collect statistics
+about your mail traffic,
+you should create the file
+.q /etc/sendmail.st :
+.(b
+cp /dev/null /etc/sendmail.st
+chmod 666 /etc/sendmail.st
+.)b
+This file does not grow.
+It is printed with the program
+.q mailstats/mailstats.c.
+The actual path of this file
+is defined in the
+.b S
+option of the
+.i sendmail.cf
+file.
+.sh 3 "/usr/ucb/newaliases"
+.pp
+If
+.i sendmail
+is invoked as
+.q newaliases,
+it will simulate the
+.b \-bi
+flag
+(i.e., will rebuild the alias database;
+see below).
+This should be a link to /usr/\*(SD/sendmail.
+.sh 3 "/usr/ucb/mailq"
+.pp
+If
+.i sendmail
+is invoked as
+.q mailq,
+it will simulate the
+.b \-bp
+flag
+(i.e.,
+.i sendmail
+will print the contents of the mail queue;
+see below).
+This should be a link to /usr/\*(SD/sendmail.
+.sh 1 "NORMAL OPERATIONS"
+.sh 2 "``Quick'' Configuration Startup"
+.pp
+if the
+.sm FROZENCONFIG
+option is included during compilation,
+a precompiled (``frozen'') version of the configuration file
+can be created using the
+.b \-bz
+flag.
+This is really only worthwhile doing
+if you are on a slow processor with a relatively fast I/O system
+(a VAX 11/750 is a good example).
+Since it creates other problems,
+I recommend against using the frozen configuration
+on most current architectures.
+.pp
+To create the freeze file, use
+.(b
+/usr/\*(SD/sendmail \-bz
+.)b
+This creates the frozen configuration file
+.i /etc/sendmail.fc .
+This file is an image of
+.i sendmail 's
+data space after reading in the configuration file.
+If this file exists,
+it is used instead of
+.i /etc/sendmail.cf
+.i sendmail.fc
+must be rebuilt manually every time
+.i sendmail.cf
+is changed.
+.pp
+The frozen configuration file will be ignored
+if a
+.b \-C
+flag is specified
+or if sendmail detects that it is out of date.
+However, the heuristics are not strong
+so this should not be trusted.
+.sh 2 "The System Log"
+.pp
+The system log is supported by the
+.i syslogd \|(8)
+program.
+.sh 3 "Format"
+.pp
+Each line in the system log
+consists of a timestamp,
+the name of the machine that generated it
+(for logging from several machines
+over the local area network),
+the word
+.q sendmail: ,
+and a message.
+.sh 3 "Levels"
+.pp
+If you have
+.i syslogd \|(8)
+or an equivalent installed,
+you will be able to do logging.
+There is a large amount of information that can be logged.
+The log is arranged as a succession of levels.
+At the lowest level
+only extremely strange situations are logged.
+At the highest level,
+even the most mundane and uninteresting events
+are recorded for posterity.
+As a convention,
+log levels under ten
+are considered generally
+.q useful;
+log levels above 64
+are reserved for debugging purposes.
+Levels from 11\-64 are reserved for verbose information
+that some sites might want.
+.pp
+A complete description of the log levels
+is given in section 4.6.
+.sh 2 "The Mail Queue"
+.pp
+The mail queue should be processed transparently.
+However, you may find that manual intervention is sometimes necessary.
+For example,
+if a major host is down for a period of time
+the queue may become clogged.
+Although sendmail ought to recover gracefully when the host comes up,
+you may find performance unacceptably bad in the meantime.
+.sh 3 "Printing the queue"
+.pp
+The contents of the queue can be printed
+using the
+.i mailq
+command
+(or by specifying the
+.b \-bp
+flag to sendmail):
+.(b
+mailq
+.)b
+This will produce a listing of the queue id's,
+the size of the message,
+the date the message entered the queue,
+and the sender and recipients.
+.sh 3 "Forcing the queue"
+.pp
+.i Sendmail
+should run the queue automatically
+at intervals.
+The algorithm is to read and sort the queue,
+and then to attempt to process all jobs in order.
+When it attempts to run the job,
+.i sendmail
+first checks to see if the job is locked.
+If so, it ignores the job.
+.pp
+There is no attempt to insure that only one queue processor
+exists at any time,
+since there is no guarantee that a job cannot take forever
+to process
+(however,
+.i sendmail
+does include heuristics to try to abort jobs
+that are taking absurd amounts of time;
+technically, this violates RFC 821, but is blessed by RFC 1123).
+Due to the locking algorithm,
+it is impossible for one job to freeze the entire queue.
+However,
+an uncooperative recipient host
+or a program recipient
+that never returns
+can accumulate many processes in your system.
+Unfortunately,
+there is no completely general way to solve this.
+.pp
+In some cases,
+you may find that a major host going down
+for a couple of days
+may create a prohibitively large queue.
+This will result in
+.i sendmail
+spending an inordinate amount of time
+sorting the queue.
+This situation can be fixed by moving the queue to a temporary place
+and creating a new queue.
+The old queue can be run later when the offending host returns to service.
+.pp
+To do this,
+it is acceptable to move the entire queue directory:
+.(b
+cd /var/spool
+mv mqueue omqueue; mkdir mqueue; chmod 700 mqueue
+.)b
+You should then kill the existing daemon
+(since it will still be processing in the old queue directory)
+and create a new daemon.
+.pp
+To run the old mail queue,
+run the following command:
+.(b
+/usr/\*(SD/sendmail \-oQ/var/spool/omqueue \-q
+.)b
+The
+.b \-oQ
+flag specifies an alternate queue directory
+and the
+.b \-q
+flag says to just run every job in the queue.
+If you have a tendency toward voyeurism,
+you can use the
+.b \-v
+flag to watch what is going on.
+.pp
+When the queue is finally emptied,
+you can remove the directory:
+.(b
+rmdir /var/spool/omqueue
+.)b
+.sh 2 "The Alias Database"
+.pp
+The alias database exists in two forms.
+One is a text form,
+maintained in the file
+.i /etc/aliases.
+The aliases are of the form
+.(b
+name: name1, name2, ...
+.)b
+Only local names may be aliased;
+e.g.,
+.(b
+eric@prep.ai.MIT.EDU: eric@CS.Berkeley.EDU
+.)b
+will not have the desired effect.
+Aliases may be continued by starting any continuation lines
+with a space or a tab.
+Blank lines and lines beginning with a sharp sign
+(\c
+.q # )
+are comments.
+.pp
+The second form is processed by the
+.i dbm \|(3)
+(or
+.i db \|(3))
+library.
+This form is in the files
+.i /etc/aliases.dir
+and
+.i /etc/aliases.pag.
+This is the form that
+.i sendmail
+actually uses to resolve aliases.
+This technique is used to improve performance.
+.pp
+You can also use
+.sm NIS -based
+alias files.
+For example, the specification:
+.(b
+OA/etc/aliases
+OAnis:mail.aliases@my.nis.domain
+.)b
+will first search the /etc/aliases file
+and then the map named
+.q mail.aliases
+in
+.q my.nis.domain .
+.sh 3 "Rebuilding the alias database"
+.pp
+The DB or DBM version of the database
+may be rebuilt explicitly by executing the command
+.(b
+newaliases
+.)b
+This is equivalent to giving
+.i sendmail
+the
+.b \-bi
+flag:
+.(b
+/usr/\*(SD/sendmail \-bi
+.)b
+.pp
+If the
+.q D
+option is specified in the configuration,
+.i sendmail
+will rebuild the alias database automatically
+if possible
+when it is out of date.
+Auto-rebuild can be dangerous
+on heavily loaded machines
+with large alias files;
+if it might take more than five minutes
+to rebuild the database,
+there is a chance that several processes will start the rebuild process
+simultaneously.
+.pp
+If you have multiple aliases databases specified,
+the
+.b \-bi
+flag rebuilds all the database types it understands
+(for example, it can rebuild dbm databases but not nis databases).
+.sh 3 "Potential problems"
+.pp
+There are a number of problems that can occur
+with the alias database.
+They all result from a
+.i sendmail
+process accessing the DBM version
+while it is only partially built.
+This can happen under two circumstances:
+One process accesses the database
+while another process is rebuilding it,
+or the process rebuilding the database dies
+(due to being killed or a system crash)
+before completing the rebuild.
+.pp
+Sendmail has two techniques to try to relieve these problems.
+First, it ignores interrupts while rebuilding the database;
+this avoids the problem of someone aborting the process
+leaving a partially rebuilt database.
+Second,
+at the end of the rebuild
+it adds an alias of the form
+.(b
+@: @
+.)b
+(which is not normally legal).
+Before sendmail will access the database,
+it checks to insure that this entry exists\**.
+.(f
+\**The
+.q a
+option is required in the configuration
+for this action to occur.
+This should normally be specified
+unless you are running
+.i delivermail
+in parallel with
+.i sendmail.
+.)f
+.sh 3 "List owners"
+.pp
+If an error occurs on sending to a certain address,
+say
+.q \fIx\fP ,
+.i sendmail
+will look for an alias
+of the form
+.q owner-\fIx\fP
+to receive the errors.
+This is typically useful
+for a mailing list
+where the submitter of the list
+has no control over the maintenance of the list itself;
+in this case the list maintainer would be the owner of the list.
+For example:
+.(b
+unix-wizards: eric@ucbarpa, wnj@monet, nosuchuser,
+       sam@matisse
+owner-unix-wizards: eric@ucbarpa
+.)b
+would cause
+.q eric@ucbarpa
+to get the error that will occur
+when someone sends to
+unix-wizards
+due to the inclusion of
+.q nosuchuser
+on the list.
+.pp
+List owners also cause the envelope sender address to be modified.
+The contents of the owner alias are used if they point to a single user,
+otherwise the name of the alias itself is used.
+For this reason, and to obey Internet conventions,
+a typical scheme would be:
+.(b
+list:  some, set, of, addresses
+list-request:  list, administrators
+owner-list:    list-request
+.)b
+.sh 2 "User Information Database"
+.pp
+If you have a version of
+.i sendmail
+with the user information database
+compiled in,
+and you have specified one or more databases using the
+.b U
+option,
+the databases will be searched for a
+.i user :maildrop
+entry.
+If found, the mail will be sent to the specified address.
+.pp
+If the first token passed to user part of the
+.q local
+mailer is an at sign,
+the at sign will be stripped off
+and this step will be skipped.
+.sh 2 "Per-User Forwarding (.forward Files)"
+.pp
+As an alternative to the alias database,
+any user may put a file with the name
+.q .forward
+in his or her home directory.
+If this file exists,
+.i sendmail
+redirects mail for that user
+to the list of addresses listed in the .forward file.
+For example, if the home directory for user
+.q mckusick
+has a .forward file with contents:
+.(b
+mckusick@ernie
+kirk@calder
+.)b
+then any mail arriving for
+.q mckusick
+will be redirected to the specified accounts.
+.pp
+Actually, the configuration file defines a sequence of filenames to check.
+By default, this is the user's .forward file,
+but can be defined to be more generally using the
+.b J
+option.
+If you change this,
+you will have to inform your user base of the change;
+\&.forward is pretty well incorporated into the collective subconscious.
+.sh 2 "Special Header Lines"
+.pp
+Several header lines have special interpretations
+defined by the configuration file.
+Others have interpretations built into
+.i sendmail
+that cannot be changed without changing the code.
+These builtins are described here.
+.sh 3 "Return-Receipt-To:"
+.pp
+If this header is sent,
+a message will be sent to any specified addresses
+when the final delivery is complete,
+that is,
+when successfully delivered to a mailer with the
+.b l
+flag (local delivery) set in the mailer descriptor.
+.sh 3 "Errors-To:"
+.pp
+If errors occur anywhere during processing,
+this header will cause error messages to go to
+the listed addresses.
+This is intended for mailing lists.
+.pp
+The Errors-To: header was created in the bad old days
+when UUCP didn't understand the distinction between an envelope and a header;
+this was a hack to provide what should now be passed
+as the envelope sender address.
+It should go away.
+It is only used if the
+.b l
+option is set.
+.sh 3 "Apparently-To:"
+.pp
+If a message comes in with no recipients listed in the message
+(in a To:, Cc:, or Bcc: line)
+then
+.i sendmail
+will add an
+.q "Apparently-To:"
+header line for any recipients it is aware of.
+This is not put in as a standard recipient line
+to warn any recipients that the list is not complete.
+.pp
+At least one recipient line is required under RFC 822.
+.sh 2 "IDENT Protocol Support"
+.pp
+.i Sendmail
+supports the IDENT protocol as defined in RFC 1413.
+Although this enhances identification
+of the author of an email message
+by doing a ``call back'' to the originating system to include
+the owner of a particular TCP connection
+in the audit trail
+it is in no sense perfect;
+a determined forger can easily spoof the IDENT protocol.
+The following description is excerpted from RFC 1413:
+.ba +5
+6.  Security Considerations
+.lp
+The information returned by this protocol is at most as trustworthy
+as the host providing it OR the organization operating the host.  For
+example, a PC in an open lab has few if any controls on it to prevent
+a user from having this protocol return any identifier the user
+wants.  Likewise, if the host has been compromised the information
+returned may be completely erroneous and misleading.
+.lp
+The Identification Protocol is not intended as an authorization or
+access control protocol.  At best, it provides some additional
+auditing information with respect to TCP connections.  At worst, it
+can provide misleading, incorrect, or maliciously incorrect
+information.
+.lp
+The use of the information returned by this protocol for other than
+auditing is strongly discouraged.  Specifically, using Identification
+Protocol information to make access control decisions - either as the
+primary method (i.e., no other checks) or as an adjunct to other
+methods may result in a weakening of normal host security.
+.lp
+An Identification server may reveal information about users,
+entities, objects or processes which might normally be considered
+private.  An Identification server provides service which is a rough
+analog of the CallerID services provided by some phone companies and
+many of the same privacy considerations and arguments that apply to
+the CallerID service apply to Identification.  If you wouldn't run a
+"finger" server due to privacy considerations you may not want to run
+this protocol.
+.ba
+.sh 1 "ARGUMENTS"
+.pp
+The complete list of arguments to
+.i sendmail
+is described in detail in Appendix A.
+Some important arguments are described here.
+.sh 2 "Queue Interval"
+.pp
+The amount of time between forking a process
+to run through the queue
+is defined by the
+.b \-q
+flag.
+If you run in mode
+.b f
+or
+.b a
+this can be relatively large,
+since it will only be relevant
+when a host that was down comes back up.
+If you run in
+.b q
+mode
+it should be relatively short,
+since it defines the maximum amount of time that a message
+may sit in the queue.
+.pp
+RFC 1123 section 5.3.1.1 says that this value should be at least 30 minutes
+(although that probably doesn't make sense if you use ``queue-only'' mode).
+.sh 2 "Daemon Mode"
+.pp
+If you allow incoming mail over an IPC connection,
+you should have a daemon running.
+This should be set by your
+.i /etc/rc
+file using the
+.b \-bd
+flag.
+The
+.b \-bd
+flag and the
+.b \-q
+flag may be combined in one call:
+.(b
+/usr/\*(SD/sendmail \-bd \-q30m
+.)b
+.sh 2 "Forcing the Queue"
+.pp
+In some cases you may find that the queue has gotten clogged for some reason.
+You can force a queue run
+using the
+.b \-q
+flag (with no value).
+It is entertaining to use the
+.b \-v
+flag (verbose)
+when this is done to watch what happens:
+.(b
+/usr/\*(SD/sendmail \-q \-v
+.)b
+.pp
+You can also limit the jobs to those with a particular queue identifier,
+sender, or recipient
+using one of the queue modifiers.
+For example,
+.q \-qRberkeley
+restricts the queue run to jobs that have the string
+.q berkeley
+somewhere in one of the recipient addresses.
+Similarly,
+.q \-qSstring
+limits the run to particular senders and
+.q \-qIstring
+limits it to particular identifiers.
+.sh 2 "Debugging"
+.pp
+There are a fairly large number of debug flags
+built into
+.i sendmail .
+Each debug flag has a number and a level,
+where higher levels means to print out more information.
+The convention is that levels greater than nine are
+.q absurd,
+i.e.,
+they print out so much information that you wouldn't normally
+want to see them except for debugging that particular piece of code.
+Debug flags are set using the
+.b \-d
+option;
+the syntax is:
+.(b
+.ta \w'debug-option  'u
+debug-flag:    \fB\-d\fP debug-list
+debug-list:    debug-option [ , debug-option ]
+debug-option:  debug-range [ . debug-level ]
+debug-range:   integer | integer \- integer
+debug-level:   integer
+.)b
+where spaces are for reading ease only.
+For example,
+.(b
+\-d12  Set flag 12 to level 1
+\-d12.3        Set flag 12 to level 3
+\-d3-17        Set flags 3 through 17 to level 1
+\-d3-17.4      Set flags 3 through 17 to level 4
+.)b
+For a complete list of the available debug flags
+you will have to look at the code
+(they are too dynamic to keep this documentation up to date).
+.sh 2 "Trying a Different Configuration File"
+.pp
+An alternative configuration file
+can be specified using the
+.b \-C
+flag; for example,
+.(b
+/usr/\*(SD/sendmail \-Ctest.cf
+.)b
+uses the configuration file
+.i test.cf
+instead of the default
+.i /etc/sendmail.cf.
+If the
+.b \-C
+flag has no value
+it defaults to
+.i sendmail.cf
+in the current directory.
+.sh 2 "Changing the Values of Options"
+.pp
+Options can be overridden using the
+.b \-o
+flag.
+For example,
+.(b
+/usr/\*(SD/sendmail \-oT2m
+.)b
+sets the
+.b T
+(timeout) option to two minutes
+for this run only.
+.pp
+Some options have security implications.
+Sendmail allows you to set these,
+but refuses to run as root thereafter.
+.sh 1 "TUNING"
+.pp
+There are a number of configuration parameters
+you may want to change,
+depending on the requirements of your site.
+Most of these are set
+using an option in the configuration file.
+For example,
+the line
+.q OT5d
+sets option
+.q T
+to the value
+.q 5d
+(five days).
+.pp
+Most of these options have appropriate defaults for most sites.
+However,
+sites having very high mail loads may find they need to tune them
+as appropriate for their mail load.
+In particular,
+sites experiencing a large number of small messages,
+many of which are delivered to many recipients,
+may find that they need to adjust the parameters
+dealing with queue priorities.
+.sh 2 "Timeouts"
+.pp
+All time intervals are set
+using a scaled syntax.
+For example,
+.q 10m
+represents ten minutes, whereas
+.q 2h30m
+represents two and a half hours.
+The full set of scales is:
+.(b
+.ta 4n
+s      seconds
+m      minutes
+h      hours
+d      days
+w      weeks
+.)b
+.sh 3 "Queue interval"
+.pp
+The argument to the
+.b \-q
+flag
+specifies how often a sub-daemon will run the queue.
+This is typically set to between fifteen minutes
+and one hour.
+RFC 1123 section 5.3.1.1 recommends that this be at least 30 minutes.
+.sh 3 "Read timeouts"
+.pp
+It is possible to time out when reading the standard input
+or when reading from a remote SMTP server.
+These timeouts are set using the
+.b r
+option in the configuration file.
+The argument is a list of
+.i keyword=value
+pairs.
+The recognized keywords, their default values, and the minimum values
+allowed by RFC 1123 section 5.3.2 are:
+.nr ii 1i
+.ip initial
+The wait for the initial 220 greeting message
+[5m, 5m].
+.ip helo
+The wait for a reply from a HELO or EHLO command
+[5m, unspecified].
+This may require a host name lookup, so
+five minutes is probably a reasonable minimum.
+.ip mail\(dg
+The wait for a reply from a MAIL command
+[10m, 5m].
+.ip rcpt\(dg
+The wait for a reply from a RCPT command
+[1h, 5m].
+This should be long
+because it could be pointing at a list
+that takes a long time to expand.
+.ip datainit\(dg
+The wait for a reply from a DATA command
+[5m, 2m].
+.ip datablock\(dg
+The wait for reading a data block
+(that is, the body of the message).
+[1h, 3m].
+This should be long because it also applies to programs
+piping input to
+.i sendmail
+which have no guarantee of promptness.
+.ip datafinal\(dg
+The wait for a reply from the dot terminating a message.
+[1h, 10m].
+If this is shorter than the time actually needed
+for the receiver to deliver the message,
+duplicates will be generated.
+This is discussed in RFC 1047.
+.ip rset
+The wait for a reply from a RSET command
+[5m, unspecified].
+.ip quit
+The wait for a reply from a QUIT command
+[2m, unspecified].
+.ip misc
+The wait for a reply from miscellaneous (but short) commands
+such as NOOP (no-operation) and VERB (go into verbose mode).
+[2m, unspecified].
+.ip command\(dg
+In server SMTP,
+the time to wait for another command.
+[1h, 5m].
+.lp
+For compatibility with old configuration files,
+if no ``keyword='' is specified,
+all the timeouts marked with \(dg are set to the indicated value.
+.pp
+Many of the RFC 1123 minimum values
+may well be too short.
+.i Sendmail
+was designed to the RFC 822 protocols,
+which did not specify read timeouts;
+hence,
+.i sendmail
+does not guarantee to reply to messages promptly.
+In particular, a
+.q RCPT
+command specifying a mailing list
+will expand and verify the entire list;
+a large list on a slow system
+may take more than five minutes\**.
+.(f
+\**This verification includes looking up every address
+with the name server;
+this involves network delays,
+and can in some cases can be considerable.
+.)f
+I recommend a one hour timeout \*-
+since this failure is rare,
+a long timeout is not onerous
+and may ultimately help reduce network load.
+.pp
+For example, the line:
+.(b
+Orcommand=25m,datablock=3h
+.)b
+sets the server SMTP command timeout to 25 minutes
+and the input data block timeout to three hours.
+.sh 3 "Message timeouts"
+.pp
+After sitting in the queue for a few days,
+a message will time out.
+This is to insure that at least the sender is aware
+of the inability to send a message.
+The timeout is typically set to three days.
+This timeout is set using the
+.b T
+option in the configuration file.
+.pp
+The time of submission is set in the queue,
+rather than the amount of time left until timeout.
+As a result, you can flush messages that have been hanging
+for a short period
+by running the queue
+with a short message timeout.
+For example,
+.(b
+/usr/\*(SD/sendmail \-oT1d \-q
+.)b
+will run the queue
+and flush anything that is one day old.
+.pp
+Since this option is global,
+and since you can not
+.i "a priori"
+know how long another host outside your domain will be down,
+a five day timeout is recommended.
+This allows a recipient to fix the problem even if it occurs
+at the beginning of a long weekend.
+RFC 1123 section 5.3.1.1 says that this parameter
+should be ``at least 4\-5 days''.
+.pp
+The
+.b T
+option can also take a second timeout indicating a time after which
+a warning message should be sent;
+the two timeouts are separated by a slash.
+For example, the value
+.(b
+5d/4h
+.)b
+causes email to fail after five days,
+but a warning message will be sent after four hours.
+This should be large enough that the message will have been tried
+several times.
+.sh 2 "Forking During Queue Runs"
+.pp
+By setting the
+.b Y
+option,
+.i sendmail
+will fork before each individual message
+while running the queue.
+This will prevent
+.i sendmail
+from consuming large amounts of memory,
+so it may be useful in memory-poor environments.
+However, if the
+.b Y
+option is not set,
+.i sendmail
+will keep track of hosts that are down during a queue run,
+which can improve performance dramatically.
+.pp
+If the
+.b Y
+option is set,
+.i sendmail
+can not use connection caching.
+.sh 2 "Queue Priorities"
+.pp
+Every message is assigned a priority when it is first instantiated,
+consisting of the message size (in bytes)
+offset by the message class times the
+.q "work class factor"
+and the number of recipients times the
+.q "work recipient factor."
+The priority is used to order the queue.
+Higher numbers for the priority mean that the message will be processed later
+when running the queue.
+.pp
+The message size is included so that large messages are penalized
+relative to small messages.
+The message class allows users to send
+.q "high priority"
+messages by including a
+.q Precedence:
+field in their message;
+the value of this field is looked up in the
+.b P
+lines of the configuration file.
+Since the number of recipients affects the amount of load a message presents
+to the system,
+this is also included into the priority.
+.pp
+The recipient and class factors
+can be set in the configuration file using the
+.b y
+and
+.b z
+options respectively.
+They default to 30000 (for the recipient factor)
+and 1800
+(for the class factor).
+The initial priority is:
+.EQ
+pri = size - (class times bold z) + (nrcpt times bold y)
+.EN
+(Remember, higher values for this parameter actually mean
+that the job will be treated with lower priority.)
+.pp
+The priority of a job can also be adjusted each time it is processed
+(that is, each time an attempt is made to deliver it)
+using the
+.q "work time factor,"
+set by the
+.b Z
+option.
+This is added to the priority,
+so it normally decreases the precedence of the job,
+on the grounds that jobs that have failed many times
+will tend to fail again in the future.
+The
+.b Z
+option defaults to 90000.
+.sh 2 "Load Limiting"
+.pp
+.i Sendmail
+can be asked to queue (but not deliver)
+mail if the system load average gets too high
+using the
+.b x
+option.
+When the load average exceeds the value of the
+.b x
+option,
+the delivery mode is set to
+.b q
+(queue only)
+if the
+.i "Queue Factor"
+(\c
+.b q
+option)
+divided by the difference in the current load average and the
+.b x
+option
+plus one
+exceeds the priority of the message \(em
+that is, the message is queued iff:
+.EQ
+pri > { bold q } over { LA - { bold x } + 1 }
+.EN
+The
+.b q
+option defaults to 200000,
+so each point of load average is worth 200000
+priority points
+(as described above).
+.pp
+For drastic cases,
+the
+.b X
+option defines a load average at which sendmail will refuse
+to accept network connections.
+Locally generated mail
+(including incoming UUCP mail)
+is still accepted.
+.sh 2 "Delivery Mode"
+.pp
+There are a number of delivery modes that
+.i sendmail
+can operate in,
+set by the
+.q d
+configuration option.
+These modes
+specify how quickly mail will be delivered.
+Legal modes are:
+.(b
+.ta 4n
+i      deliver interactively (synchronously)
+b      deliver in background (asynchronously)
+q      queue only (don't deliver)
+.)b
+There are tradeoffs.
+Mode
+.q i
+passes the maximum amount of information to the sender,
+but is hardly ever necessary.
+Mode
+.q q
+puts the minimum load on your machine,
+but means that delivery may be delayed for up to the queue interval.
+Mode
+.q b
+is probably a good compromise.
+However, this mode can cause large numbers of processes
+if you have a mailer that takes a long time to deliver a message.
+.pp
+If you run in mode
+.q q
+(queue only)
+.i sendmail
+will not expand aliases and follow .forward files
+upon initial receipt of the mail.
+This speeds up the response to RCPT commands.
+.sh 2 "Log Level"
+.pp
+The level of logging can be set for sendmail.
+The default using a standard configuration table is level 9.
+The levels are as follows:
+.nr ii 0.5i
+.ip 0
+No logging.
+.ip 1
+Serious system failures and potential security problems.
+.ip 2
+Lost communications (network problems) and protocol failures.
+.ip 3
+Other serious failures.
+.ip 4
+Minor failures.
+.ip 5
+Message collection statistics.
+.ip 6
+Creation of error messages,
+VRFY and EXPN commands.
+.ip 7
+Delivery failures (host or user unknown, etc.).
+.ip 8
+Successful deliveries.
+.ip 9
+Messages being deferred
+(due to a host being down, etc.).
+.ip 10
+Database expansion (alias, forward, and userdb lookups).
+.ip 15
+Automatic alias database rebuilds.
+.ip 20
+Logs attempts to run locked queue files.
+These are not errors,
+but can be useful to note if your queue appears to be clogged.
+.ip 30
+Lost locks (only if using lockf instead of flock).
+.lp
+Additionally,
+values above 64 are reserved for extremely verbose debuggging output.
+No normal site would ever set these.
+.sh 2 "File Modes"
+.pp
+There are a number of files
+that may have a number of modes.
+The modes depend on what functionality you want
+and the level of security you require.
+.sh 3 "To suid or not to suid?"
+.pp
+.i Sendmail
+can safely be made
+setuid to root.
+At the point where it is about to
+.i exec \|(2)
+a mailer,
+it checks to see if the userid is zero;
+if so,
+it resets the userid and groupid to a default
+(set by the
+.b u
+and
+.b g
+options).
+(This can be overridden
+by setting the
+.b S
+flag to the mailer
+for mailers that are trusted
+and must be called as root.)
+However,
+this will cause mail processing
+to be accounted
+(using
+.i sa \|(8))
+to root
+rather than to the user sending the mail.
+.sh 3 "Should my alias database be writable?"
+.pp
+At Berkeley
+we have the alias database
+(/etc/aliases*)
+mode 644.
+While this is not as flexible as if the database
+were more 666, it avoids potential security problems
+with a globally writable database.
+.pp
+The database that
+.i sendmail
+actually used
+is represented by the two files
+.i aliases.dir
+and
+.i aliases.pag
+(both in /etc)
+(or
+.i aliases.db
+if you are running with the new Berkeley database primitives).
+The mode on these files should match the mode
+on /etc/aliases.
+If
+.i aliases
+is writable
+and the
+DBM
+files
+(\c
+.i aliases.dir
+and
+.i aliases.pag )
+are not,
+users will be unable to reflect their desired changes
+through to the actual database.
+However,
+if
+.i aliases
+is read-only
+and the DBM files are writable,
+a slightly sophisticated user
+can arrange to steal mail anyway.
+.pp
+If your DBM files are not writable by the world
+or you do not have auto-rebuild enabled
+(with the
+.q D
+option),
+then you must be careful to reconstruct the alias database
+each time you change the text version:
+.(b
+newaliases
+.)b
+If this step is ignored or forgotten
+any intended changes will also be ignored or forgotten.
+.sh 2 "Connection Caching"
+.pp
+When processing the queue,
+.b sendmail
+will try to keep the last few open connections open
+to avoid startup and shutdown costs.
+This only applies to IPC connections.
+.pp
+When trying to open a connection
+the cache is first searched.
+If an open connection is found, it is probed to see if it is still active
+by sending a
+.sm NOOP
+command.
+It is not an error if this fails;
+instead, the connection is closed and reopened.
+.pp
+Two parameters control the connection cache.
+The
+.b k
+option defines the number of simultaneous open connections
+that will be permitted.
+If it is set to zero,
+connections will be closed as quickly as possible.
+The default is one.
+This should be set as appropriate for your system size;
+it will limit the amount of system resources that
+.b sendmail
+will use during queue runs.
+.pp
+The
+.b K
+option specifies the maximum time that any cached connection
+will be permitted to idle.
+When the idle time exceeds this value
+the connection is closed.
+This number should be small
+(under ten minutes)
+to prevent you from grabbing too many resources
+from other hosts.
+The default is five minutes.
+.sh 2 "Name Server Access"
+.pp
+If your system supports the name server,
+then the probability is that
+.i sendmail
+will be using it regardless of how you configure sendmail.
+However, if you have nameserver support
+which you are not using,
+sendmail will get a
+.q "connection refused"
+message when it tries to connect to the name server
+(either by calling
+.i gethostbyname
+or by trying to look up the MX records).
+If the
+.b I
+option is set,
+.i sendmail
+will interpret this to mean a temporary failure;
+otherwise, it ignores the name server data.
+If your name server is running properly,
+the setting of this option is not relevant;
+however, it is important that it be set properly
+to make error handling work properly.
+.pp
+This option also allows you to tweak name server options.
+The command line takes a series of flags as documented in
+.i resolver (3)
+(with the leading
+.q RES_
+deleted).
+Each can be preceded by an optional `+' or `\(mi'.
+For example, the line
+.(b
+OITrue +AAONLY \(miDNSRCH
+.)b
+turns on the AAONLY (accept authoritative answers only)
+and turns off the DNSRCH (search the domain path) options.
+Most resolver libraries default DNSRCH, DEFNAMES, and RECURSE
+flags on and all others off.
+Note the use of the initial ``True'' \*-
+this is for compatibility with previous versions of sendmail,
+but is not otherwise necessary.
+.pp
+Version level 1 configurations
+turn DNSRCH and DEFNAMES off when doing delivery lookups,
+but leave them on everywhere else.
+Version 6 of
+.i sendmail
+ignores them when doing canonification lookups
+(that is, when using $[ ... $]),
+and always does the search.
+If you don't want to do automatic name extension,
+don't call $[ ... $].
+.pp
+The search rules for $[ ... $] are somewhat different than usual.
+If the name (that is, the ``...'')
+has at least one dot, it always tries the unmodified name first.
+If that fails, it tries the reduced search path,
+and lastly tries the unmodified name
+(but only for names without a dot,
+since names with a dot have already been tried).
+This allows names such as
+``utc.CS''
+to match the site in Czechoslovakia
+rather than the site in your local Computer Science department.
+It also prefers A and CNAME records over MX records \*-
+that is, if it finds an MX record it makes note of it,
+but keeps looking.
+This way, if you have a wildcard MX record matching your domain,
+it will not assume that all names match.
+.sh 2 "Moving the Per-User Forward Files"
+.pp
+Some sites mount each user's home directory
+from a local disk on their workstation,
+so that local access is fast.
+However, the result is that .forward file lookups are slow.
+In some cases,
+mail can even be delivered on machines inappropriately
+because of a file server being down.
+The performance can be especially bad if you run the automounter.
+.pp
+The
+.b J
+option allows you to set a path of forward files.
+For example, the config file line
+.(b
+OJ/var/forward/$u:$z/.forward
+.)b
+would first look for a file with the same name as the user's login
+in /var/forward;
+if that is not found (or is inaccessible)
+the file
+.q \&.forward
+in the user's home directory is searched.
+A truly perverse site could also search by sender
+by using $r, $s, or $f.
+.pp
+If you create a directory such as /var/forward,
+it should be mode 1777
+(that is, the sticky bit should be set).
+Users should create the files mode 644.
+.sh 2 "Free Space"
+.pp
+On systems that have the
+.i statfs (2)
+system call,
+you can specify a minimum number of free blocks on the queue filesystem
+using the
+.b b
+option.
+If there are fewer than the indicated number of blocks free
+on the filesystem on which the queue is mounted
+the SMTP server will reject mail
+with the
+452 error code.
+This invites the SMTP client to try again later.
+.pp
+Beware of setting this option too high;
+it can cause rejection of email
+when that mail would be processed without difficulty.
+.pp
+This option can also specify an advertised
+.q "maximum message size"
+for hosts that speak ESMTP.
+.sh 2 "Privacy Flags"
+.pp
+The
+.b p
+option allows you to set certain
+``privacy''
+flags.
+Actually, many of them don't give you any extra privacy,
+rather just insisting that client SMTP servers
+use the HELO command
+before using certain commands.
+.pp
+The option takes a series of flag names;
+the final privacy is the inclusive or of those flags.
+For example:
+.(b
+Op needmailhelo, noexpn
+.)b
+insists that the HELO or EHLO command be used before a MAIL command is accepted
+and disables the EXPN command.
+.pp
+The
+.q restrictmailq
+option restricts printing the queue to the group that owns the queue directory.
+It is absurd to set this if you don't also protect the logs.
+.sh 2 "Send to Me Too"
+.pp
+Normally,
+.i sendmail
+deletes the (envelope) sender from any list expansions.
+For example, if
+.q matt
+sends to a list that contains
+.q matt
+as one of the members he won't get a copy of the message.
+If the
+.b \-m
+(me too)
+command line flag, or if the
+.b m
+option is set in the configuration file,
+this behaviour is supressed.
+Some sites like to run the
+.sm SMTP
+daemon with
+.b \-m .
+.sh 1 "THE WHOLE SCOOP ON THE CONFIGURATION FILE"
+.pp
+This section describes the configuration file
+in detail,
+including hints on how to write one of your own
+if you have to.
+.pp
+There is one point that should be made clear immediately:
+the syntax of the configuration file
+is designed to be reasonably easy to parse,
+since this is done every time
+.i sendmail
+starts up,
+rather than easy for a human to read or write.
+On the
+.q "future project"
+list is a
+configuration-file compiler.
+.pp
+An overview of the configuration file
+is given first,
+followed by details of the semantics.
+.sh 2 "Configuration File Lines"
+.pp
+The configuration file is organized as a series of lines,
+each of which begins with a single character
+defining the semantics for the rest of the line.
+Lines beginning with a space or a tab
+are continuation lines
+(although the semantics are not well defined in many places).
+Blank lines and lines beginning with a sharp symbol
+(`#')
+are comments.
+.sh 3 "R and S \*- rewriting rules"
+.pp
+The core of address parsing
+are the rewriting rules.
+These are an ordered production system.
+.i Sendmail
+scans through the set of rewriting rules
+looking for a match on the left hand side
+(LHS)
+of the rule.
+When a rule matches,
+the address is replaced by the right hand side
+(RHS)
+of the rule.
+.pp
+There are several sets of rewriting rules.
+Some of the rewriting sets are used internally
+and must have specific semantics.
+Other rewriting sets
+do not have specifically assigned semantics,
+and may be referenced by the mailer definitions
+or by other rewriting sets.
+.pp
+The syntax of these two commands are:
+.(b F
+.b S \c
+.i n
+.)b
+Sets the current ruleset being collected to
+.i n .
+If you begin a ruleset more than once
+it deletes the old definition.
+.(b F
+.b R \c
+.i lhs
+.i rhs
+.i comments
+.)b
+The
+fields must be separated
+by at least one tab character;
+there may be embedded spaces
+in the fields.
+The
+.i lhs
+is a pattern that is applied to the input.
+If it matches,
+the input is rewritten to the
+.i rhs .
+The
+.i comments
+are ignored.
+.pp
+Macro expansions of the form
+.b $ \c
+.i x
+are performed when the configuration file is read.
+Expansions of the form
+.b $& \c
+.i x
+are performed at run time using a somewhat less general algorithm.
+This for is intended only for referencing internally defined macros
+such as
+.b $h
+that are changed at runtime.
+.sh 4 "The left hand side"
+.pp
+The left hand side of rewriting rules contains a pattern.
+Normal words are simply matched directly.
+Metasyntax is introduced using a dollar sign.
+The metasymbols are:
+.(b
+.ta \w'\fB$=\fP\fIx\fP  'u
+\fB$*\fP       Match zero or more tokens
+\fB$+\fP       Match one or more tokens
+\fB$\-\fP      Match exactly one token
+\fB$=\fP\fIx\fP        Match any phrase in class \fIx\fP
+\fB$~\fP\fIx\fP        Match any word not in class \fIx\fP
+.)b
+If any of these match,
+they are assigned to the symbol
+.b $ \c
+.i n
+for replacement on the right hand side,
+where
+.i n
+is the index in the LHS.
+For example,
+if the LHS:
+.(b
+$\-:$+
+.)b
+is applied to the input:
+.(b
+UCBARPA:eric
+.)b
+the rule will match, and the values passed to the RHS will be:
+.(b
+.ta 4n
+$1     UCBARPA
+$2     eric
+.)b
+.pp
+Additionally, the LHS can include
+.b $@
+to match zero tokens.
+This is
+.i not
+bound to a
+.b $ \c
+.i N

+The final value of ruleset
+.i n
+then becomes
+the substitution for this rule.
+.pp
+The
+.b $#
+syntax should
+.i only
+be used in ruleset zero.

+A RHS may also be preceded by a

+to control evaluation.
+A
+.b $@

+.(b
+local-part@host-domain-spec

+If no

+host-domain-spec
+.i may
+be appended from the

+(if the
+.b C
+flag is set in the mailer definition
+corresponding to the
+.i sending
+mailer).
+Ruleset three
+is applied by sendmail
+before doing anything with any address.
+.pp
+Ruleset zero
+is applied after ruleset three
+to addresses that are going to actually specify recipients.
+It must resolve to a
+.i "{mailer, host, user}"
+triple.
+The
+.i mailer
+must be defined in the mailer definitions
+from the configuration file.
+The
+.i host
+is defined into the
+.b $h
+macro
+for use in the argv expansion of the specified mailer.
+.pp
+Rulesets one and two
+are applied to all sender and recipient addresses respectively.
+They are applied before any specification
+in the mailer definition.
+They must never resolve.
+.pp
+Ruleset four is applied to all addresses
+in the message.
+It is typically used
+to translate internal to external form.
+.sh 4 "IPC mailers"
+.pp
+Some special processing occurs
+if the ruleset zero resolves to an IPC mailer
+(that is, a mailer that has
+.q [IPC]
+listed as the Path in the
+.b M
+configuration line.
+The host name passed after
+.q $@
+has MX expansion performed;
+this looks the name up in DNS to find alternate delivery sites.
+.pp
+The host name can also be provided as a dotted quad in square brackets;
+for example:
+.(b
+[128.32.149.78]
+.)b
+This causes direct conversion of the numeric value
+to a TCP/IP host address.
+.pp
+The host name passed in after the
+.q $@
+may also be a colon-separated list of hosts.
+Each is separately MX expanded and the results are concatenated
+to make (essentially) one long MX list.
+The intent here is to create
+.q fake
+MX records that are not published in DNS
+for private internal networks.
+.pp
+As a final special case, the host name can be passed in
+as a text string
+in square brackets:
+.(b
+[ucbvax.berkeley.edu]
+.)b
+This form avoids the MX mapping.
+.b N.B.:
+This is intended only for situations where you have a network firewall,
+so that your MX record points to a gateway machine;
+this machine could then do direct delivery to machines
+within your local domain.
+Use of this feature directly violates RFC 1123 section 5.3.5:
+it should not be used lightly.
+.sh 3 "D \*- define macro"
+.pp
+Macros are named with a single character.
+These may be selected from the entire ASCII set,
+but user-defined macros
+should be selected from the set of upper case letters only.
+Lower case letters
+and special symbols
+are used internally.
+.pp
+The syntax for macro definitions is:
+.(b F
+.b D \c
+.i x\|val
+.)b
+where
+.i x
+is the name of the macro
+and
+.i val
+is the value it should have.
+.pp
+Macros are interpolated
+using the construct
+.b $ \c
+.i x ,
+where
+.i x
+is the name of the macro to be interpolated.
+This interpolation is done when the configuration file is read,
+except in
+.b M
+lines.
+The special construct
+.b $& \c
+.i x
+can be used in
+.b R
+lines to get deferred interpolation.
+.pp
+Conditionals can be specified using the syntax:
+.(b
+$?x text1 $| text2 $.
+.)b
+This interpolates
+.i text1
+if the macro
+.b $x
+is set,
+and
+.i text2
+otherwise.
+The
+.q else
+(\c
+.b $| )
+clause may be omitted.
+.pp
+Lower case macro names are reserved to have
+special semantics,
+used to pass information in or out of sendmail,
+and special characters are reserved to
+provide conditionals, etc.
+Upper case names
+(that is,
+.b $A
+through
+.b $Z )
+are specifically reserved for configuration file authors.
+.pp
+The following macros
+.i must
+be defined to transmit information into
+.i sendmail:
+.(b
+.ta 4n
+e      The SMTP entry message
+j      The \*(lqofficial\*(rq domain name for this site
+l      The format of the UNIX from line
+n      The name of the daemon (for error messages)
+o      The set of "operators" in addresses
+q      default format of sender address
+.)b
+The
+.b $e
+macro is printed out when SMTP starts up.
+The first word must be the
+.b $j
+macro.
+The
+.b $j
+macro
+should be in RFC821 format.
+The
+.b $l
+and
+.b $n
+macros can be considered constants
+except under terribly unusual circumstances.
+The
+.b $o
+macro consists of a list of characters
+which will be considered tokens
+and which will separate tokens
+when doing parsing.
+For example, if
+.q @
+were in the
+.b $o
+macro, then the input
+.q a@b
+would be scanned as three tokens:
+.q a,
+.q @,
+and
+.q b.
+Finally, the
+.b $q
+macro specifies how an address should appear in a message
+when it is defaulted.
+For example, on our system these definitions are:
+.(b
+De$j Sendmail $v/$Z ready at $b
+DnMAILER-DAEMON
+DlFrom $g  $d
+Do.:%@!^/[]
+Dq$?x$x <$g>$|$g$.
+Dj$w
+.)b
+An acceptable alternative for the
+.b $q
+macro is
+.q "$g$?x ($x)$." .
+These correspond to the following two formats:
+.(b
+Eric Allman <eric@CS.Berkeley.EDU>
+eric@CS.Berkeley.EDU (Eric Allman)
+.)b
+.i Sendmail
+properly quotes names that have special characters
+if the first form is used.
+.pp
+Some macros are defined by
+.i sendmail
+for interpolation into argv's for mailers
+or for other contexts.
+These macros are:
+.(b
+a      The origination date in RFC 822 format
+b      The current date in RFC 822 format
+c      The hop count
+d      The date in UNIX (ctime) format
+f      The sender (from) address
+g      The sender address relative to the recipient
+h      The recipient host
+i      The queue id
+k      The UUCP node name (from the uname system call)
+m      The domain part of the \fIgethostname\fP return value
+p      Sendmail's pid
+r      Protocol used to receive the message
+s      Sender's host name
+t      A numeric representation of the current time
+u      The recipient user
+v      The version number of sendmail
+w      The hostname of this site
+x      The full name of the sender
+z      The home directory of the recipient
+_      The validated sender address
+.)b
+.pp
+There are three types of dates that can be used.
+The
+.b $a
+and
+.b $b
+macros are in RFC 822 format;
+.b $a
+is the time as extracted from the
+.q Date:
+line of the message
+(if there was one),
+and
+.b $b
+is the current date and time
+(used for postmarks).
+If no
+.q Date:
+line is found in the incoming message,
+.b $a
+is set to the current time also.
+The
+.b $d
+macro is equivalent to the
+.b $b
+macro in UNIX
+(ctime)
+format.
+.pp
+The
+.b $f
+macro is the id of the sender
+as originally determined;
+when mailing to a specific host
+the
+.b $g
+macro is set to the address of the sender
+.ul
+relative to the recipient.
+For example,
+if I send to
+.q bollard@matisse.CS.Berkeley.EDU
+from the machine
+.q vangogh.CS.Berkeley.EDU
+the
+.b $f
+macro will be
+.q eric
+and the
+.b $g
+macro will be
+.q eric@vangogh.CS.Berkeley.EDU.
+.pp
+The
+.b $x
+macro is set to the full name of the sender.
+This can be determined in several ways.
+It can be passed as flag to
+.i sendmail.
+The second choice is the value of the
+.q Full-name:
+line in the header if it exists,
+and the third choice is the comment field
+of a
+.q From:
+line.
+If all of these fail,
+and if the message is being originated locally,
+the full name is looked up in the
+.i /etc/passwd
+file.
+.pp
+When sending,
+the
+.b $h ,
+.b $u ,
+and
+.b $z
+macros get set to the host, user, and home directory
+(if local)
+of the recipient.
+The first two are set from the
+.b $@
+and
+.b $:
+part of the rewriting rules, respectively.
+.pp
+The
+.b $p
+and
+.b $t
+macros are used to create unique strings
+(e.g., for the
+.q Message-Id:
+field).
+The
+.b $i
+macro is set to the queue id on this host;
+if put into the timestamp line
+it can be extremely useful for tracking messages.
+The
+.b $v
+macro is set to be the version number of
+.i sendmail ;
+this is normally put in timestamps
+and has been proven extremely useful for debugging.
+The
+.b $w
+macro is set to the name of this host
+if it can be determined.
+The
+.b $c
+field is set to the
+.q "hop count,"
+i.e., the number of times this message has been processed.
+This can be determined
+by the
+.b \-h
+flag on the command line
+or by counting the timestamps in the message.
+.pp
+The
+.b $r
+and
+.b $s
+fields are set to the protocol used to communicate with sendmail
+and the sending hostname.
+The
+.b $_
+is set to a validated sender host name.
+If the sender is running an RFC 1413 compliant IDENT server,
+it will include the user name on that host.
+.sh 3 "C and F \*- define classes"
+.pp
+Classes of phrases may be defined
+to match on the left hand side of rewriting rules,
+where a
+.q phrase
+is a sequence of characters that do not contain space characters.
+For example
+a class of all local names for this site
+might be created
+so that attempts to send to oneself
+can be eliminated.
+These can either be defined directly in the configuration file
+or read in from another file.
+Classes may be given names
+from the set of upper case letters.
+Lower case letters and special characters
+are reserved for system use.
+.pp
+The syntax is:
+.(b F
+.b C \c
+.i c\|phrase1
+.i phrase2...
+.br
+.b F \c
+.i c\|file
+.)b
+The first form defines the class
+.i c
+to match any of the named words.
+It is permissible to split them among multiple lines;
+for example, the two forms:
+.(b
+CHmonet ucbmonet
+.)b
+and
+.(b
+CHmonet
+CHucbmonet
+.)b
+are equivalent.
+The second form
+reads the elements of the class
+.i c
+from the named
+.i file .
+.pp
+The
+.b $~
+(match entries not in class)
+only matches a single word;
+multi-word entries in the class are ignored in this context.
+.pp
+The class
+.b $=w
+is set to be the set of all names
+this host is known by.
+This can be used to match local hostnames.
+.pp
+The class
+.b $=k
+is set to be the same as
+.b $k ,
+that is, the UUCP node name.
+.sh 3 "M \*- define mailer"

+are defined in this line.
+The format is:
+.(b F
+.b M \c
+.i name ,
+{\c
+.i field =\c

+.)b
+where
+.i name
+is the name of the mailer

+.)b
+Only the first character of the field name is checked.
+.pp
+The following flags may be set in the mailer description.
+Any other flags may be used freely
+to conditionally assign headers to messages
+destined for particular mailers.
+.nr ii 4n
+.ip a
+Run Extended SMTP (ESMTP) protocol (defined in RFCs 1425, 1426, and 1427).
+.ip b
+Force a blank line on the end of a message.
+This is intended to work around some stupid versions of
+/bin/mail
+that require a blank line, but do not provide it themselves.
+It would not normally be used on network mail.
+.ip c
+Do not include comments in addresses.
+This should only be used if you have to work around
+a remote mailer that gets confused by comments.
+.ip C
+If mail is
+.i received
+from a mailer with this flag set,
+any addresses in the header that do not have an at sign
+(\c
+.q @ )
+after being rewritten by ruleset three
+will have the
+.q @domain
+clause from the sender
+tacked on.
+This allows mail with headers of the form:
+.(b
+From: usera@hosta
+To: userb@hostb, userc
+.)b
+to be rewritten as:
+.(b
+From: usera@hosta
+To: userb@hostb, userc@hosta
+.)b
+automatically.
+.ip D
+This mailer wants a
+.q Date:
+header line.
+.ip e
+This mailer is expensive to connect to,
+so try to avoid connecting normally;
+any necessary connection will occur during a queue run.
+.ip E
+Escape lines beginning with
+.q From
+in the message with a `>' sign.
+.ip f
+The mailer wants a
+.b \-f
+.i from
+flag,
+but only if this is a network forward operation
+(i.e.,
+the mailer will give an error
+if the executing user
+does not have special permissions).
+.ip F
+This mailer wants a
+.q From:
+header line.
+.ip g
+Normally,
+.i sendmail
+sends internally generated email (e.g., error messages)
+using the null return address\**
+.(f
+\**Actually, this only applies to SMTP,
+which uses the ``MAIL FROM:<>'' command.
+.)f
+as required by RFC 1123.
+However, some mailers don't accept a null return address.
+If necessary,
+you can set the
+.b g
+flag to prevent
+.i sendmail
+from obeying the standards;
+error messages will be sent as from the MAILER-DAEMON
+(actually, the value of the
+.b $n
+macro).
+.ip h
+Upper case should be preserved in host names
+for this mailer.
+.ip I
+This mailer will be speaking SMTP
+to another
+.i sendmail
+\*-
+as such it can use special protocol features.
+This option is not required
+(i.e.,
+if this option is omitted the transmission will still operate successfully,
+although perhaps not as efficiently as possible).
+.ip l
+This mailer is local
+(i.e.,
+final delivery will be performed).
+.ip L
+Limit the line lengths as specified in RFC821.
+This deprecated option should be replaced by the
+.b L=
+mail declaration.
+For historic reasons, the
+.b L
+flag also sets the
+.b 7
+flag.
+.ip m
+This mailer can send to multiple users
+on the same host
+in one transaction.
+When a
+.b $u
+macro occurs in the
+.i argv
+part of the mailer definition,
+that field will be repeated as necessary
+for all qualifying users.
+.ip M
+This mailer wants a
+.q Message-Id:
+header line.
+.ip n
+Do not insert a UNIX-style
+.q From
+line on the front of the message.
+.ip p
+Use the route-addr style reverse-path in the SMTP
+.q "MAIL FROM:"
+command
+rather than just the return address;
+although this is required in RFC821 section 3.1,
+many hosts do not process reverse-paths properly.
+Reverse-paths are officially discouraged by RFC 1123.
+.ip P
+This mailer wants a
+.q Return-Path:
+line.
+.ip r
+Same as
+.b f ,
+but sends a
+.b \-r
+flag.
+.ip s
+Strip quote characters off of the address
+before calling the mailer.
+.ip S
+Don't reset the userid
+before calling the mailer.
+This would be used in a secure environment
+where
+.i sendmail
+ran as root.
+This could be used to avoid forged addresses.
+This flag is suppressed if given from an
+.q unsafe
+environment
+(e.g, a user's mail.cf file).
+.ip u
+Upper case should be preserved in user names
+for this mailer.
+.ip U
+This mailer wants Unix-style
+.q From
+lines with the ugly UUCP-style
+.q "remote from <host>"
+on the end.
+.ip x
+This mailer wants a
+.q Full-Name:
+header line.
+.ip X
+This mailer want to use the hidden dot algorithm
+as specified in RFC821;
+basically,
+any line beginning with a dot
+will have an extra dot prepended
+(to be stripped at the other end).
+This insures that lines in the message containing a dot
+will not terminate the message prematurely.
+.ip 7
+Strip all output to seven bits.
+This is the default if the
+.b L
+flag is set.
+Note that setting this is not
+sufficient to get full eight bit data passed through
+.i sendmail .
+If the
+.b 7
+option is set, this is essentially always set,
+since the eighth bit was stripped on input.
+.pp
+The mailer with the special name
+.q error
+can be used to generate a user error.
+The (optional) host field is an exit status to be returned,
+and the user field is a message to be printed.
+The exit status may be numeric or one of the values
+USAGE, NOUSER, NOHOST, UNAVAILABLE, SOFTWARE, TEMPFAIL, PROTOCOL, or CONFIG
+to return the corresponding EX_ exit code.
+For example, the entry:
+.(b
+$#error $@ NOHOST $: Host unknown in this domain
+.)b
+on the RHS of a rule
+will cause the specified error to be generated
+and the
+.q "Host unknown"
+exit status to be returned
+if the LHS matches.
+This mailer is only functional in ruleset zero.
+.pp
+The mailer named
+.q local
+.i must
+be defined in every configuration file.
+This is used to deliver local mail,
+and is treated specially in several ways.
+Additionally, three other mailers named
+.q prog ,
+.q *file* ,
+and
+.q *include*
+may be defined to tune the delivery of messages to programs,
+files,
+and :include: lists respectively.
+They default to:
+.(b
+Mprog, P=/bin/sh, F=lsD, A=sh \-c $u
+M*file*, P=/dev/null, F=lsDFMPEu, A=FILE
+M*include*, P=/dev/null, F=su, A=INCLUDE
+.)b
+.pp
+The Sender and Recipient rewriting sets
+may either be a simple integer
+or may be two integers separated by a slash;
+if so, the first rewriting set is applied to envelope
+addresses
+and the second is applied to headers.
+.pp
+The Directory
+is actually a colon-separated path of directories to try.
+For example, the definition
+.q D=$z:/
+first tries to execute in the recipient's home directory;
+if that is not available,
+it tries to execute in the root of the filesystem.
+This is intended to be used only on the
+.q prog
+mailer,
+since some shells (such as
+.i csh )
+refuse to execute if they cannot read the home directory.
+Since the queue directory is not normally readable by normal users
+.i csh
+scripts as recipients can fail.
+.sh 3 "H \*- define header"
+.pp
+The format of the header lines that sendmail inserts into the message
+are defined by the
+.b H
+line.
+The syntax of this line is:
+.(b F
+.b H [\c
+.b ? \c
+.i mflags \c
+.b ? ]\c
+.i hname \c
+.b :
+.i htemplate
+.)b
+Continuation lines in this spec
+are reflected directly into the outgoing message.
+The
+.i htemplate
+is macro expanded before insertion into the message.
+If the
+.i mflags
+(surrounded by question marks)
+are specified,
+at least one of the specified flags
+must be stated in the mailer definition
+for this header to be automatically output.
+If one of these headers is in the input
+it is reflected to the output
+regardless of these flags.
+.pp
+Some headers have special semantics
+that will be described below.
+.sh 3 "O \*- set option"
+.pp
+There are a number of
+.q random
+options that
+can be set from a configuration file.
+Options are represented by single characters.
+The syntax of this line is:
+.(b F
+.b O \c
+.i o\|value
+.)b
+This sets option
+.i o
+to be
+.i value .
+Depending on the option,
+.i value
+may be a string, an integer,
+a boolean
+(with legal values
+.q t ,
+.q T ,
+.q f ,
+or
+.q F ;
+the default is TRUE),
+or
+a time interval.
+.pp
+The options supported are:
+.nr ii 1i
+.ip a\fIN\fP
+If set,
+wait up to
+.i N
+minutes for an
+.q @:@
+entry to exist in the alias database
+before starting up.
+If it does not appear in
+.i N
+minutes,
+rebuild the database
+(if the
+.b D
+option is also set)
+or issue a warning.
+.ip "A\fIspec, spec, ...\fP"
+Specify possible alias file(s).
+Each
+.i spec
+should be in the format
+``\c
+.i class \c
+.b :
+.i file ''
+where
+.i class \c
+.b :
+is optional and defaults to ``implicit''.
+Depending on how
+.b sendmail
+is compiled, valid classes are
+.q implicit
+(search through a compiled-in list of alias file types,
+for back compatibility),
+.q hash
+(if
+.sm NEWDB
+is specified),
+.q dbm
+(if
+.sm NDBM
+is specified),
+.q stab
+(internal symbol table \*- not normally used
+unless you have no other database lookup),
+or
+.q nis
+(if
+.sm NIS
+is specified).
+If a list of
+.i spec s
+are provided,
+.i sendmail
+searches them in order.
+.ip b\fIN\fP/\fIM\fP
+Insist on at least
+.i N
+blocks free on the filesystem that holds the queue files
+before accepting email via SMTP.
+If there is insufficient space
+.i sendmail
+gives a 452 response
+to the MAIL command.
+This invites the sender to try again later.
+The optional
+.i M
+is a maximum message size advertised in the ESMTP EHLO response.
+It is currently otherwise unused.
+.ip B\fIc\fP
+Set the blank substitution character to
+.i c .
+Unquoted spaces in addresses are replaced by this character.
+Defaults to space (i.e., no change is made).
+.ip c
+If an outgoing mailer is marked as being expensive,
+don't connect immediately.
+This requires that queueing be compiled in,
+since it will depend on a queue run process to
+actually send the mail.
+.ip C\fIN\fP
+Checkpoints the queue every
+.i N
+(default 10)
+addresses sent.
+If your system crashes during delivery to a large list,
+this prevents retransmission to any but the last
+.I N
+recipients.
+.ip d\fIx\fP
+Deliver in mode
+.i x .
+Legal modes are:
+.(b
+.ta 4n
+i      Deliver interactively (synchronously)
+b      Deliver in background (asynchronously)
+q      Just queue the message (deliver during queue run)
+.)b
+Defaults to ``b'' if no option is specified,
+``i'' if it is specified but given no argument
+(i.e., ``Od'' is equivalent to ``Odi'').
+.ip D
+If set,
+rebuild the alias database if necessary and possible.
+If this option is not set,
+.i sendmail
+will never rebuild the alias database
+unless explicitly requested
+using
+.b \-bi .
+.ip e\fIx\fP
+Dispose of errors using mode
+.i x .
+The values for
+.i x
+are:
+.(b
+p      Print error messages (default)
+q      No messages, just give exit status
+m      Mail back errors
+w      Write back errors (mail if user not logged in)
+e      Mail back errors and give zero exit stat always
+.)b
+.ip E\fIfile/message\fP
+Prepend error messages with the indicated message.
+If it begins with a slash,
+it is assumed to be the pathname of a file
+containing a message (this is the recommended setting).
+Otherwise, it is a literal message.
+The error file might contain the name, email address, and/or phone number
+of a local postmaster who could provide assistance
+in to end users.
+If the option is missing or null,
+or if it names a file which does not exist or which is not readable,
+no message is printed.
+.ip f
+Save
+Unix-style
+.q From
+lines at the front of headers.
+Normally they are assumed redundant
+and discarded.
+.ip F\fImode\fP
+The file mode for queue files.
+.ip g\fIn\fP
+Set the default group id
+for mailers to run in
+to
+.i n .
+Defaults to 1.
+.ip G
+Allow fuzzy matching on the GECOS field.
+If this flag is set,
+and the usual user name lookups fail
+(that is, there is no alias with this name and a
+.i getpwnam
+fails),
+sequentially search the password file
+for a matching entry in the GECOS field.
+This also requires that MATCHGECOS
+be turned on during compilation.
+This option is not recommended.
+.ip h\fIN\fP
+The maximum hop count.
+Messages that have been processed more than
+.i N
+times are assumed to be in a loop and are rejected.
+Defaults to 25.
+.ip H\fIfile\fP
+Specify the help file
+for SMTP.
+.ip i
+Ignore dots in incoming messages.
+This is always disabled (that is, dots are always accepted)
+when reading SMTP mail.
+.ip I
+Insist that the BIND name server be running
+to resolve host names.
+If this is not set and the name server is not running,
+the
+.i /etc/hosts
+file will be considered complete.
+In general, you do want to set this option
+if your
+.i /etc/hosts
+file does not include all hosts known to you
+or if you are using the MX (mail forwarding) feature of the BIND name server.
+The name server will still be consulted
+even if this option is not set, but
+.i sendmail
+will feel free to resort to reading
+.i /etc/hosts
+if the name server is not available.
+Thus, you should
+.i never
+set this option if you do not run the name server.
+.ip j
+If set, send error messages in MIME format
+(see RFC1341 and RFC1344 for details).
+.ip J\fIpath\fP
+Set the path for searching for users' .forward files.
+The default is
+.q $z/.forward .
+Some sites that use the automounter may prefer to change this to
+.q /var/forward/$u
+to search a file with the same name as the user in a system directory.
+It can also be set to a sequence of paths separated by colons;
+.i sendmail
+stops at the first file it can successfully and safely open.
+For example,
+.q /var/forward/$u:$z/.forward
+will search first in /var/forward/\c
+.i username
+and then in
+.i ~username /.forward
+(but only if the first file does not exist).
+.ip k\fIN\fP
+The maximum number of open connections that will be cached at a time.
+The default is one.
+This delays closing the the current connection until
+either this invocation of sendmail needs to connect to another host
+or it terminates.
+Setting it to zero defaults to the old behavior,
+that is, connections are closed immediately.
+.ip K\fItimeout\fP
+The maximum amount of time a cached connection will be permitted to idle
+without activity.
+If this time is exceeded,
+the connection is immediately closed.
+This value should be small (on the order of ten minutes).
+Before
+.b sendmail
+uses a cached connection,
+it always sends a NOOP (no operation) command
+to check the connection;
+if this fails, it reopens the connection.
+This keeps your end from failing if the other end times out.
+The point of this option is to be a good network neighbor
+and avoid using up excessive resources
+on the other end.
+The default is five minutes.
+.ip l
+If there is an
+.q Errors-To:
+header, send error messages to the addresses listed there.
+They normally go to the envelope sender.
+Use of this option causes sendmail to violate RFC 1123.
+.ip L\fIn\fP
+Set the default log level to
+.i n .
+Defaults to 9.
+.ip m
+Send to me too,
+even if I am in an alias expansion.
+.ip M\fIx\|value\fP
+Set the macro
+.i x
+to
+.i value .
+This is intended only for use from the command line.
+.ip n
+Validate the RHS of aliases when rebuilding the alias database.
+.ip o
+Assume that the headers may be in old format,
+i.e.,
+spaces delimit names.
+This actually turns on
+an adaptive algorithm:
+if any recipient address contains a comma, parenthesis,
+or angle bracket,
+it will be assumed that commas already exist.
+If this flag is not on,
+only commas delimit names.
+Headers are always output with commas between the names.
+.ip O\fIoptions\fP
+Set server SMTP options.
+The options are
+.i key=value
+pairs.
+Known keys are:
+.(b
+.ta 1i
+Port   Name/number of listening port (defaults to "smtp")
+Addr   Address mask (defaults INADDR_ANY)
+Family Address family (defaults to INET)
+Listen Size of listen queue (defaults to 10)
+.)b
+The
+.i Addr ess
+mask may be a numeric address in dot notation
+or a network name.
+.ip p\fI\|opt,opt,...\fP
+Set the privacy
+.i opt ions.
+``Privacy'' is really a misnomer;
+many of these are just a way of insisting on stricter adherence
+to the SMTP protocol.
+The
+.i opt ions
+can be selected from:
+.(b
+.ta \w'needvrfyhelo'u+3n
+public Allow open access
+needmailhelo   Insist on HELO or EHLO command before MAIL
+needexpnhelo   Insist on HELO or EHLO command before EXPN
+noexpn Disallow EXPN entirely
+needvrfyhelo   Insist on HELO or EHLO command before VRFY
+novrfy Disallow VRFY entirely
+restrictmailq  Restrict mailq command
+goaway Disallow essentially all SMTP status queries
+.)b
+The
+.q goaway
+pseudo-flag sets all flags except
+.q restrictmailq .
+If mailq is restricted,
+only people in the same group as the queue directory
+can print the queue.
+.ip P\fIpostmaster\fP
+If set,
+copies of error messages will be sent to the named
+.i postmaster .
+Only the header of the failed message is sent.
+Since most errors are user problems,
+this is probably not a good idea on large sites,
+and arguably contains all sorts of privacy violations,
+but it seems to be popular with certain operating systems vendors.
+.ip q\fIfactor\fP
+Use
+.i factor
+as the multiplier in the map function
+to decide when to just queue up jobs rather than run them.
+This value is divided by the difference between the current load average
+and the load average limit
+(\c
+.b x
+flag)
+to determine the maximum message priority
+that will be sent.
+Defaults to 600000.
+.ip Q\fIdir\fP
+Use the named
+.i dir
+as the queue directory.
+.ip r\|\fItimeouts\fP
+Timeout reads after
+.i time
+interval.
+The
+.i timeouts
+argument is a list of
+.i keyword=value
+pairs.
+The recognized timeouts and their default values, and their
+minimum values specified in RFC 1123 section 5.3.2 are:
+.(b
+.ta \w'datafinal'u+3n
+initial        wait for initial greeting message [5m, 5m]
+helo   reply to HELO or EHLO command [5m, none]
+mail   reply to MAIL command [10m, 5m]
+rcpt   reply to RCPT command [1h, 5m]
+datainit       reply to DATA command [5m, 2m]
+datablock      data block read [1h, 3m]
+datafinal      reply to final ``.'' in data [1h, 10m]
+rset   reply to RSET command [5m, none]
+quit   reply to QUIT command [2m, none]
+misc   reply to NOOP and VERB commands [2m, none]
+command        command read [1h, 5m]
+.)b
+All but
+.q command
+apply to client SMTP.
+For back compatibility,
+a timeout with no ``keyword='' part
+will set all of the longer values.
+.ip s
+Be super-safe when running things,
+i.e.,
+always instantiate the queue file,
+even if you are going to attempt immediate delivery.
+.i Sendmail
+always instantiates the queue file
+before returning control the the client
+under any circumstances.
+.ip S\fIfile\fP
+Log statistics in the named
+.i file .
+.ip t\fIS,D\fP
+Set the local time zone name to
+.i S
+for standard time and
+.i D
+for daylight time;
+this is only used under version six.
+.ip T\fIrtime/wtime\fP
+Set the queue timeout to
+.i rtime .
+After this interval,
+messages that have not been successfully sent
+will be returned to the sender.
+Defaults to five days.
+The optional
+.i wtime
+is the time after which a warning message is sent.
+If it is missing or zero
+then no warning messages are sent.
+.ip u\fIn\fP
+Set the default userid for mailers to
+.i n .
+Mailers without the
+.i S
+flag in the mailer definition
+will run as this user.
+Defaults to 1.
+.ip U\fIudbspec\fP
+The user database specification.
+.ip v
+Run in verbose mode.
+If this is set,
+.i sendmail
+adjusts options
+.b c
+(don't connect to expensive mailers)
+and
+.b d
+(delivery mode)
+so that all mail is delivered completely
+in a single job
+so that you can see the entire delivery process.
+Option
+.b v
+should
+.i never
+be set in the configuration file;
+it is intended for command line use only.
+.ip V\fIfallbackhost\fP
+If specified, the
+.i fallbackhost
+acts like a very low priority MX
+on every host.
+This is intended to be used by sites with poor network connectivity.
+.ip x\fILA\fP
+When the system load average exceeds
+.i LA ,
+just queue messages
+(i.e., don't try to send them).
+Defaults to 8.
+.ip X\fILA\fP
+When the system load average exceeds
+.i LA ,
+refuse incoming SMTP connections.
+Defaults to 12.
+.ip y\fIfact\fP
+The indicated
+.i fact or
+is added to the priority (thus
+.i lowering
+the priority of the job)
+for each recipient,
+i.e., this value penalizes jobs with large numbers of recipients.
+Defaults to 30000.
+.ip Y
+If set,
+deliver each job that is run from the queue in a separate process.
+Use this option if you are short of memory,
+since the default tends to consume considerable amounts of memory
+while the queue is being processed.
+.ip z\fIfact\fP
+The indicated
+.i fact or
+is multiplied by the message class
+(determined by the Precedence: field in the user header
+and the
+.b P
+lines in the configuration file)
+and subtracted from the priority.
+Thus, messages with a higher Priority: will be favored.
+Defaults to 1800.
+.ip Z\fIfact\fP
+The
+.i fact or
+is added to the priority
+every time a job is processed.
+Thus,
+each time a job is processed,
+its priority will be decreased by the indicated value.
+In most environments this should be positive,
+since hosts that are down are all too often down for a long time.
+Defaults to 90000.
+.ip 7
+Strip input to seven bits for compatibility with old systems.
+This shouldn't be necessary.
+.lp
+All options can be specified on the command line using the
+\-o flag,
+but most will cause
+.i sendmail
+to relinquish its setuid permissions.
+The options that will not cause this are
+b, d, e, E, i, L, m, o, p, r, s, v, C, and 7.
+Also, M (define macro) when defining the r or s macros
+is also considered
+.q safe .
+.sh 3 "P \*- precedence definitions"
+.pp
+Values for the
+.q "Precedence:"
+field may be defined using the
+.b P
+control line.
+The syntax of this field is:
+.(b
+\fBP\fP\fIname\fP\fB=\fP\fInum\fP
+.)b
+When the
+.i name
+is found in a
+.q Precedence:
+field,
+the message class is set to
+.i num .
+Higher numbers mean higher precedence.
+Numbers less than zero
+have the special property
+that if an error occurs during processing
+the body of the message will not be returned;
+this is expected to be used for
+.q "bulk"
+mail such as through mailing lists.
+The default precedence is zero.
+For example,
+our list of precedences is:
+.(b
+Pfirst-class=0
+Pspecial-delivery=100
+Plist=\-30
+Pbulk=\-60
+Pjunk=\-100
+.)b
+People writing mailing list exploders
+are encouraged to use
+.q "Precedence: list" .
+Older versions of
+.i sendmail
+(which discarded all error returns for negative precedences)
+didn't recognize this name, giving it a default precedence of zero.
+This allows list maintainers to see error returns
+on both old and new versions of
+.i sendmail .
+.sh 3 "V \*- configuration version level"
+.pp
+To provide compatibility with old configuration files,
+the
+.b V
+line has been added to define some very basic semantics
+of the configuration file.
+These are not intended to be long term supports;
+rather, they describe compatibility features
+which will probably be removed in future releases.
+.pp
+.q Old
+configuration files are defined as version level one.
+Version level two files make the following changes:
+.np
+Host name canonification ($[ ... $])
+appends a dot if the name is recognized;
+this gives the config file a way of finding out if anything matched.
+(Actually, this just initializes the
+.q host
+map with the
+.q \-a.
+flag \*- you can reset it to anything you prefer
+by declaring the map explicitly.)
+.np
+Default host name extension is consistent throughout processing;
+version level one configurations turned off domain extension
+(that is, adding the local domain name)
+during certain points in processing.
+Version level two configurations are expected to include a trailing dot
+to indicate that the name is already canonical.
+.np
+Local names that are not aliases
+are passed through a new distinguished ruleset five;
+this can be used to append a local relay.
+This behaviour can be prevented by resolving the local name
+with an initial `@'.
+That is, something that resolves to a local mailer and a user name of
+.q vikki
+will be passed through ruleset five,
+but a user name of
+.q @vikki
+will have the `@' stripped,
+will not be passed through ruleset five,
+but will otherwise be treated the same as the prior example.
+The expectation is that this might be used to implement a policy
+where mail sent to
+.q vikki
+was handled by a central hub,
+but mail sent to
+.q vikki@localhost
+was delivered directly.
+.pp
+Version level three files
+allow # initiated comments on all lines.
+Exceptions are backslash escaped # marks
+and the $# syntax.
+.sh 3 "K \*- key file declaration"
+.pp
+Special maps can be defined using the line:
+.(b
+Kmapname mapclass arguments
+.)b
+The
+.i mapname
+is the handle by which this map is referenced in the rewriting rules.
+The
+.i mapclass
+is the name of a type of map;
+these are compiled in to sendmail.
+The
+.i arguments
+are interpreted depending on the class;
+typically,
+there would be a single argument naming the file containing the map.
+.pp
+Maps are referenced using the syntax:
+.(b
+$( \fImap\fP \fIkey\fP $@ \fIarguments\fP $: \fIdefault\fP $)
+.)b
+where either or both of the
+.i arguments
+or
+.i default
+portion may be omitted.
+The
+.i arguments
+may appear more than once.
+The indicated
+.i key
+and
+.i arguments
+are passed to the appropriate mapping function.
+If it returns a value, it replaces the input.
+If it does not return a value and the
+.i default
+is specified, the
+.i default
+replaces the input.
+Otherwise, the input is unchanged.
+.pp
+During replacement of either a map value or default
+the string
+.q %\fIn\fP
+(where
+.i n
+is a digit)
+is replaced by the corresponding
+.i argument .
+Argument zero
+is always the database key.
+For example, the rule
+.(b
+.ta 1.5i
+R$- ! $+       $: $(uucp $1 $@ $2 $: %1 @ %0 . UUCP $)
+.)b
+Looks up the UUCP name in a (user defined) UUCP map;
+if not found it turns it into
+.q \&.UUCP
+form.
+The database might contain records like:
+.(b
+decvax %1@%0.DEC.COM
+research       %1@%0.ATT.COM
+.)b
+.pp
+The built in map with both name and class
+.q host
+is the host name canonicalization lookup.
+Thus,
+the syntax:
+.(b
+$(host \fIhostname\fP$)
+.)b
+is equivalent to:
+.(b
+$[\fIhostname\fP$]
+.)b
+.pp
+There are four predefined database lookup classes:
+.q dbm ,
+.q btree ,
+.q hash ,
+and
+.q nis .
+The first requires that sendmail be compiled with the
+.b ndbm
+library;
+the second two require the
+.b db
+library,
+and the third requires that sendmail be compiled with NIS support.
+All four accept as arguments the some optional flags
+and a filename (or a mapname for NIS).
+Known flags are:
+.ip "\-o"
+Indicates that this map is optional \*- that is,
+if it cannot be opened,
+no error is produced,
+and sendmail will behave as if the map existed but was empty.
+.ip "\-N"
+Normally sendmail does not include the trailing null byte
+on a string as part of the key.
+If this flag is indicated,
+it will be included.
+This is for compatibility with some methods of building the maps.
+.ip "\-a\fIx\fP"
+Append the character
+.i x
+on successful matches.
+For example, the default
+.i host
+map appends a dot on successful matches.
+.ip "\-f"
+Fold upper to lower case before looking up the key.
+.ip "\-m"
+Match only (without replacing the value).
+If you only care about the existence of a key and not the value
+(as you might when searching the NIS map
+.q hosts.byname
+for example),
+this flag prevents the map from substituting the value.
+However,
+The \-a argument is still appended on a match,
+and the default is still taken if the match fails.
+.pp
+The
+.i dbm
+map appends the strings
+.q \&.pag
+and
+.q \&.dir
+to the given filename;
+the two
+.i db -based
+maps append
+.q \&.db .
+.pp
+The program
+.i makemap (8)
+can be used to build any of the three database-oriented maps.
+It takes the following flags:
+.ip \-f
+Do not fold upper to lower case in the map.
+.ip \-N
+Include null bytes in keys.
+.ip \-o
+Append to an existing (old) file.
+.ip \-r
+Allow replacement of existing keys;
+normally, re-inserting an existing key is an error.
+.ip \-v
+Print what is happening.
+.pp
+There are also two builtin maps that are,
+strictly speaking,
+not database lookups.
+.pp
+The
+.q host
+map does host domain canonification;
+given a host name it calls the name server
+to find the canonical name for that host.
+.pp
+The
+.q dequote
+map strips double quotes (") from a name.
+It does not strip backslashes.
+It will not strip quotes if the resulting string
+would contain unscannable syntax
+(that is, basic errors like unbalanced angle brackets;
+more sophisticated errors such as unknown hosts are not checked).
+The intent is for use when trying to accept mail from systems such as
+DECnet
+that routinely quote odd syntax such as
+.(b
+"49ers::ubell"
+.)b
+A typical usage is probably something like:
+.(b
+Kdequote dequote
+
+\&...
+
+R$\-   $: $(dequote $1 $)
+R$\- $+        $: $>3 $1 $2
+.)b
+Care must be taken to prevent unexpected results;
+for example,
+.(b
+"|someprogram < input > output"
+.)b
+will have quotes stripped,
+but the result is probably not what you had in mind.
+Fortunately these cases are rare.
+.pp
+New classes can be added in the routine
+.b setupmaps
+in file
+.b conf.c .
+.sh 2 "Building a Configuration File From Scratch"
+.pp
+Building a configuration table from scratch is an extremely difficult job.
+Fortunately,
+it is almost never necessary to do so;
+nearly every situation that may come up
+may be resolved by changing an existing table.
+In any case,
+it is critical that you understand what it is that you are trying to do
+and come up with a philosophy for the configuration table.
+This section is intended to explain what the real purpose
+of a configuration table is
+and to give you some ideas
+for what your philosophy might be.
+.pp
+.b "Do not even consider"
+writing your own configuration file
+without carefully studying
+RFC 821, 822, and 1123.
+You should also read RFC 976
+if you are doing UUCP exchange.
+.sh 3 "What you are trying to do"
+.pp
+The configuration table has three major purposes.
+The first and simplest
+is to set up the environment for
+.i sendmail .
+This involves setting the options,
+defining a few critical macros,
+etc.
+Since these are described in other places,
+we will not go into more detail here.
+.pp
+The second purpose is to rewrite addresses in the message.
+This should typically be done in two phases.
+The first phase maps addresses in any format
+into a canonical form.
+This should be done in ruleset three.
+The second phase maps this canonical form
+into the syntax appropriate for the receiving mailer.
+.i Sendmail
+does this in three subphases.
+Rulesets one and two
+are applied to all sender and recipient addresses respectively.
+After this,
+you may specify per-mailer rulesets
+for both sender and recipient addresses;
+this allows mailer-specific customization.
+Finally,
+ruleset four is applied to do any default conversion
+to external form.
+.pp
+The third purpose
+is to map addresses into the actual set of instructions
+necessary to get the message delivered.
+Ruleset zero must resolve to the internal form,
+which is in turn used as a pointer to a mailer descriptor.
+The mailer descriptor describes the interface requirements
+of the mailer.
+.sh 3 "Philosophy"
+.pp
+The particular philosophy you choose will depend heavily
+on the size and structure of your organization.
+I will present a few possible philosophies here.
+There are as many philosophies as there are config designers;
+feel free to develop your own.
+.pp
+One general point applies to all of these philosophies:
+it is almost always a mistake
+to try to do full host route resolution.
+For example,
+if you are on a UUCP-only site
+and you are trying to get names of the form
+.q user@host
+to the Internet,
+it does not pay to route them to
+.q xyzvax!decvax!ucbvax!c70!user@host
+since you then depend on several links not under your control,
+some of which are likely to misparse it anyway.
+The best approach to this problem
+is to simply forward the message for
+.q user@host
+to
+.q xyzvax
+and let xyzvax
+worry about it from there.
+In summary,
+just get the message closer to the destination,
+rather than determining the full path.
+.sh 4 "Large site, many hosts \*- minimum information"
+.pp
+Berkeley is an example of a large site,
+i.e., more than two or three hosts
+and multiple mail connections.
+We have decided that the only reasonable philosophy
+in our environment
+is to designate one host as the guru for our site.
+It must be able to resolve any piece of mail it receives.
+The other sites should have the minimum amount of information
+they can get away with.
+In addition,
+any information they do have
+should be hints rather than solid information.
+.pp
+For example,
+a typical site on our local ether network is
+.q monet
+(actually
+.q monet.CS.Berkeley.EDU ).
+When monet receives mail for delivery,
+it checks whether it knows
+that the destination host is directly reachable;
+if so, mail is sent to that host.
+If it receives mail for any unknown host,
+it just passes it directly to
+.q ucbvax.CS.Berkeley.EDU ,
+our master host.
+Ucbvax may determine that the host name is illegal
+and reject the message,
+or may be able to do delivery.
+However, it is important to note that when a new mail connection is added,
+the only host that
+.i must
+have its tables updated
+is ucbvax;
+the others
+.i may
+be updated if convenient,
+but this is not critical.
+.pp
+This picture is slightly muddied
+due to network connections that are not actually located
+on ucbvax.
+For example,
+some UUCP connections are currently on
+.q ucbarpa.
+However,
+monet
+.i "does not"
+know about this;
+the information is hidden totally between ucbvax and ucbarpa.
+Mail going from monet to a UUCP host
+is transferred via the ethernet
+from monet to ucbvax,
+then via the ethernet from ucbvax to ucbarpa,
+and then is submitted to UUCP.
+Although this involves some extra hops,
+we feel this is an acceptable tradeoff.
+.pp
+An interesting point is that it would be possible
+to update monet
+to send appropriate UUCP mail directly to ucbarpa
+if the load got too high;
+if monet failed to note a host as connected to ucbarpa
+it would go via ucbvax as before,
+and if monet incorrectly sent a message to ucbarpa
+it would still be sent by ucbarpa
+to ucbvax as before.
+The only problem that can occur is loops,
+for example,
+if ucbarpa thought that ucbvax had the UUCP connection
+and vice versa.
+For this reason,
+updates should
+.i always
+happen to the master host first.
+.pp
+This philosophy results as much from the need
+to have a single source for the configuration files
+(typically built using
+.i m4 \|(1)
+or some similar tool)
+as any logical need.
+Maintaining more than three separate tables by hand
+is essentially an impossible job.
+.sh 4 "Small site \*- complete information"
+.pp
+A small site
+(two or three hosts and few external connections)
+may find it more reasonable to have complete information
+at each host.
+This would require that each host
+know exactly where each network connection is,
+possibly including the names of each host on that network.
+As long as the site remains small
+and the the configuration remains relatively static,
+the update problem will probably not be too great.
+.sh 4 "Single host"
+.pp
+This is in some sense the trivial case.
+The only major issue is trying to insure that you don't
+have to know too much about your environment.
+For example,
+if you have a UUCP connection
+you might find it useful to know about the names of hosts
+connected directly to you,
+but this is really not necessary
+since this may be determined from the syntax.
+.sh 4 "A completely different philosophy"
+.pp
+This is adapted from Bruce Lilly.
+Any errors in interpretation are mine.
+.pp
+Do minimal changes in ruleset 3:
+fix some common but unambiguous errors (e.g. trailing dot on domains) and
+hide bang paths foo!bar into bar@foo.UUCP.
+The resulting "canonical" form is any valid RFC822/RFC1123/RFC976 address.
+.pp
+Ruleset 0 does the bulk of the work.
+It removes the trailing "@.UUCP" that hides bang paths,
+strips anything not needed to resolve,
+e.g. the phrase from phrase <route-addr> and from named groups,
+rejects unparseable addresses using $#error,
+and finally
+resolves to a mailer/host/user triple.
+Ruleset 0 is rather lengthy
+as it has to handle 3 basic address forms:
+RFC976 bang paths,
+RFC1123 %-hacks
+(including vanilla RFC822 local-part@domain),
+and RFC822 source routes.
+It's also complicated by having to handle named lists.
+.pp
+The header rewriting rulesets 1 and 2
+remove the trailing "@.UUCP" that hides bang paths.
+Ruleset 2 also strips the $# mailer $@ host (for test mode).
+.pp
+Ruleset 4 does absolutely nothing.
+.pp
+The per-mailer rewriting rulesets conform the envelope and
+header addresses to the requirements of the specific
+mailer.
+.pp
+Lots of rulesets-as-subroutines are used.
+.pp
+As a result, header addresses are subject to minimal munging
+(per RFC1123), and the general plan is per RFC822 sect. 3.4.10.
+.sh 3 "Relevant issues"
+.pp
+The canonical form you use
+should almost certainly be as specified in
+the Internet protocols
+RFC819 and RFC822.
+Copies of these RFC's are included on the
+.i sendmail
+tape
+as
+.i doc/rfc819.lpr
+and
+.i doc/rfc822.lpr .
+.pp
+RFC822
+describes the format of the mail message itself.
+.i Sendmail
+follows this RFC closely,
+to the extent that many of the standards described in this document
+can not be changed without changing the code.
+In particular,
+the following characters have special interpretations:
+.(b
+< > ( ) " \e
+.)b
+Any attempt to use these characters for other than their RFC822
+purpose in addresses is probably doomed to disaster.
+.pp
+RFC819
+describes the specifics of the domain-based addressing.
+This is touched on in RFC822 as well.
+Essentially each host is given a name
+which is a right-to-left dot qualified pseudo-path
+from a distinguished root.
+The elements of the path need not be physical hosts;
+the domain is logical rather than physical.
+For example,
+at Berkeley
+one legal host might be
+.q a.CC.Berkeley.EDU ;
+reading from right to left,
+.q EDU
+is a top level domain
+comprising educational institutions,
+.q Berkeley
+is a logical domain name,
+.q CC
+represents the Computer Center,
+(in this case a strictly logical entity),
+and
+.q a
+is a host in the Computer Center.
+.pp
+Beware when reading RFC819
+that there are a number of errors in it.
+.sh 3 "How to proceed"
+.pp
+Once you have decided on a philosophy,
+it is worth examining the available configuration tables
+to decide if any of them are close enough
+to steal major parts of.
+Even under the worst of conditions,
+there is a fair amount of boiler plate that can be collected safely.
+.pp
+The next step is to build ruleset three.
+This will be the hardest part of the job.
+Beware of doing too much to the address in this ruleset,
+since anything you do will reflect through
+to the message.
+In particular,
+stripping of local domains is best deferred,
+since this can leave you with addresses with no domain spec at all.
+Since
+.i sendmail
+likes to append the sending domain to addresses with no domain,
+this can change the semantics of addresses.
+Also try to avoid
+fully qualifying domains in this ruleset.
+Although technically legal,
+this can lead to unpleasantly and unnecessarily long addresses
+reflected into messages.
+The Berkeley configuration files
+define ruleset nine
+to qualify domain names and strip local domains.
+This is called from ruleset zero
+to get all addresses into a cleaner form.
+.pp
+Once you have ruleset three finished,
+the other rulesets should be relatively trivial.
+If you need hints,
+examine the supplied configuration tables.
+.sh 3 "Testing the rewriting rules \*- the \-bt flag"
+.pp
+When you build a configuration table,
+you can do a certain amount of testing
+using the
+.q "test mode"
+of
+.i sendmail .
+For example,
+you could invoke
+.i sendmail
+as:
+.(b
+sendmail \-bt \-Ctest.cf
+.)b
+which would read the configuration file
+.q test.cf
+and enter test mode.
+In this mode,
+you enter lines of the form:
+.(b
+rwset address
+.)b
+where
+.i rwset
+is the rewriting set you want to use
+and
+.i address
+is an address to apply the set to.
+Test mode shows you the steps it takes
+as it proceeds,
+finally showing you the address it ends up with.
+You may use a comma separated list of rwsets
+for sequential application of rules to an input.
+For example:
+.(b
+3,1,21,4 monet:bollard
+.)b
+first applies ruleset three to the input
+.q monet:bollard.
+Ruleset one is then applied to the output of ruleset three,
+followed similarly by rulesets twenty-one and four.
+.pp
+If you need more detail,
+you can also use the
+.q \-d21
+flag to turn on more debugging.
+For example,
+.(b
+sendmail \-bt \-d21.99
+.)b
+turns on an incredible amount of information;
+a single word address
+is probably going to print out several pages worth of information.
+.pp
+You should be warned that internally,
+.b sendmail
+applies ruleset 3 to all addresses.
+In this version of sendmail, you will have to do that manually.
+For example, older versions allowed you to use
+.(b
+0 bruce@broadcast.sony.com
+.)b
+This version requires that you use:
+.(b
+3,0 bruce@broadcast.sony.com
+.)b
+.sh 3 "Building mailer descriptions"
+.pp
+To add an outgoing mailer to your mail system,
+you will have to define the characteristics of the mailer.
+.pp
+Each mailer must have an internal name.
+This can be arbitrary,
+except that the names
+.q local
+and
+.q prog
+must be defined.
+.pp
+The pathname of the mailer must be given in the P field.
+If this mailer should be accessed via an IPC connection,
+use the string
+.q [IPC]
+instead.
+.pp
+The F field defines the mailer flags.
+You should specify an
+.q f
+or
+.q r
+flag to pass the name of the sender as a
+.b \-f
+or
+.b \-r
+flag respectively.
+These flags are only passed if they were passed to
+.i sendmail,
+so that mailers that give errors under some circumstances
+can be placated.
+If the mailer is not picky
+you can just specify
+.q "\-f $g"
+in the argv template.
+If the mailer must be called as
+.b root
+the
+.q S
+flag should be given;
+this will not reset the userid
+before calling the mailer\**.
+.(f
+\**\c
+.i Sendmail
+must be running setuid to root
+for this to work.
+.)f
+If this mailer is local
+(i.e., will perform final delivery
+rather than another network hop)
+the
+.q l
+flag should be given.
+Quote characters
+(backslashes and " marks)
+can be stripped from addresses if the
+.q s
+flag is specified;
+if this is not given
+they are passed through.
+If the mailer is capable of sending to more than one user
+on the same host
+in a single transaction
+the
+.q m
+flag should be stated.
+If this flag is on,
+then the argv template containing
+.b $u
+will be repeated for each unique user
+on a given host.
+The
+.q e
+flag will mark the mailer as being
+.q expensive,
+which will cause
+.i sendmail
+to defer connection
+until a queue run\**.
+.(f
+\**The
+.q c
+configuration option must be given
+for this to be effective.
+.)f
+.pp
+An unusual case is the
+.q C
+flag.
+This flag applies to the mailer that the message is received from,
+rather than the mailer being sent to;
+if set,
+the domain spec of the sender
+(i.e., the
+.q @host.domain
+part)
+is saved
+and is appended to any addresses in the message
+that do not already contain a domain spec.
+For example,
+a message of the form:
+.(b
+From: eric@vangogh.CS.Berkeley.EDU
+To: wnj@monet.CS.Berkeley.EDU, mckusick
+.)b
+will be modified to:
+.(b
+From: eric@vangogh.CS.Berkeley.EDU
+To: wnj@monet.CS.Berkeley.EDU, mckusick@vangogh.CS.Berkeley.EDU
+.)b
+.i "if and only if"
+the
+.q C
+flag is defined in the mailer corresponding to
+.q eric@vangogh.CS.Berkeley.EDU.
+.pp
+Other flags are described
+in Appendix C.
+.pp
+The S and R fields in the mailer description
+are per-mailer rewriting sets
+to be applied to sender and recipient addresses
+respectively.
+These are applied after the sending domain is appended
+and the general rewriting sets
+(numbers one and two)
+are applied,
+but before the output rewrite
+(ruleset four)
+is applied.
+A typical use is to append the current domain
+to addresses that do not already have a domain.
+For example,
+a header of the form:
+.(b
+From: eric
+.)b
+might be changed to be:
+.(b
+From: eric@vangogh.CS.Berkeley.EDU
+.)b
+or
+.(b
+From: ucbvax!eric
+.)b
+depending on the domain it is being shipped into.
+These sets can also be used
+to do special purpose output rewriting
+in cooperation with ruleset four.
+.pp
+The E field defines the string to use
+as an end-of-line indication.
+A string containing only newline is the default.
+The usual backslash escapes
+(\er, \en, \ef, \eb)
+may be used.
+.pp
+Finally,
+an argv template is given as the E field.
+It may have embedded spaces.
+If there is no argv with a
+.b $u
+macro in it,
+.i sendmail
+will speak SMTP
+to the mailer.
+If the pathname for this mailer is
+.q [IPC],
+the argv should be
+.(b
+IPC $h [ \fIport\fP ]
+.)b
+where
+.i port
+is the optional port number
+to connect to.
+.pp
+For example,
+the specifications:
+.(b
+.ta \w'Mlocal, 'u +\w'P=/bin/mail, 'u +\w'F=rlsm, 'u +\w'S=10, 'u +\w'R=20, 'u
+Mlocal,        P=/bin/mail,    F=rlsm  S=10,   R=20,   A=mail \-d $u
+Mether,        P=[IPC],        F=meC,  S=11,   R=21,   A=IPC $h, M=100000
+.)b
+specifies a mailer to do local delivery
+and a mailer for ethernet delivery.
+The first is called
+.q local,
+is located in the file
+.q /bin/mail,
+takes a picky
+.b \-r
+flag,
+does local delivery,
+quotes should be stripped from addresses,
+and multiple users can be delivered at once;
+ruleset ten
+should be applied to sender addresses in the message
+and ruleset twenty
+should be applied to recipient addresses;
+the argv to send to a message will be the word
+.q mail,
+the word
+.q \-d,
+and words containing the name of the receiving user.
+If a
+.b \-r
+flag is inserted
+it will be between the words
+.q mail
+and
+.q \-d.
+The second mailer is called
+.q ether,
+it should be connected to via an IPC connection,
+it can handle multiple users at once,
+connections should be deferred,
+and any domain from the sender address
+should be appended to any receiver name
+without a domain;
+sender addresses should be processed by ruleset eleven
+and recipient addresses by ruleset twenty-one.
+There is a 100,000 byte limit on messages passed through this mailer.
+.sh 2 "The User Database"
+.pp
+If you have a version of sendmail with the user database package
+compiled in,
+the handling of sender and recipient addresses
+is modified.
+.pp
+The location of this database is controlled with the
+.b U
+option.
+.sh 3 "Structure of the user database"
+.pp
+The database is a sorted (BTree-based) structure.
+User records are stored with the key:
+.(b
+\fIuser-name\fP\fB:\fP\fIfield-name\fP
+.)b
+The sorted database format ensures that user records are clustered together.
+Meta-information is always stored with a leading colon.
+.pp
+Field names define both the syntax and semantics of the value.
+Defined fields include:
+.nr ii 1i
+.ip maildrop
+The delivery address for this user.
+There may be multiple values of this record.
+In particular,
+mailing lists will have one
+.i maildrop
+record for each user on the list.
+.ip "mailname"
+The outgoing mailname for this user.
+For each outgoing name,
+there should be an appropriate
+.i maildrop
+record for that name to allow return mail.
+See also
+.i :default:mailname .
+.ip mailsender
+Changes any mail sent to this address to have the indicated envelope sender.
+This is intended for mailing lists,
+and will normally be the name of an appropriate -request address.
+It is very similar to the owner-\c
+.i list
+syntax in the alias file.
+.ip fullname
+The full name of the user.
+.ip office-address
+The office address for this user.
+.ip office-phone
+The office phone number for this user.
+.ip office-fax
+The office FAX number for this user.
+.ip home-address
+The home address for this user.
+.ip home-phone
+The home phone number for this user.
+.ip home-fax
+The home FAX number for this user.
+.ip project
+A (short) description of the project this person is affiliated with.
+In the University this is often just the name of their graduate advisor.
+.ip plan
+A pointer to a file from which plan information can be gathered.
+.pp
+As of this writing,
+only a few of these fields are actually being used by sendmail:
+.i maildrop
+and
+.i mailname .
+A
+.i finger
+program that uses the other fields is planned.
+.sh 3 "User database semantics"
+.pp
+When the rewriting rules submit an address to the local mailer,
+the user name is passed through the alias file.
+If no alias is found (or if the alias points back to the same address),
+the name (with
+.q :maildrop
+appended)
+is then used as a key in the user database.
+If no match occurs (or if the maildrop points at the same address),
+forwarding is tried.
+.pp
+If the first token of the user name returned by ruleset 0
+is an
+.q @
+sign, the user database lookup is skipped.
+The intent is that the user database will act as a set of defaults
+for a cluster (in our case, the Computer Science Division);
+mail sent to a specific machine should ignore these defaults.
+.pp
+When mail is sent,
+the name of the sending user is looked up in the database.
+If that user has a
+.q mailname
+record,
+the value of that record is used as their outgoing name.
+For example, I might have a record:
+.(b
+eric:mailname  Eric.Allman@CS.Berkeley.EDU
+.)b
+This would cause my outgoing mail to be sent as Eric.Allman.
+.pp
+If a
+.q maildrop
+is found for the user,
+but no corresponding
+.q maildrop
+record exists,
+the record
+.q :default:mailname
+is consulted.
+If present, this is the name of a host to override the local host.
+For example, in our case we would set it to
+.q CS.Berkeley.EDU .
+The effect is that anyone known in the database
+gets their outgoing mail stamped as
+.q user@CS.Berkeley.EDU ,
+but people not listed in the database use the local hostname.
+.sh 1 "OTHER CONFIGURATION"
+.pp
+There are some configuration changes that can be made by
+recompiling
+.i sendmail .
+This section describes what changes can be made
+and what has to be modified to make them.
+.sh 2 "Parameters in src/Makefile"
+.pp
+These parameters are intended to describe the compilation environment,
+not site policy,
+and should normally be defined in src/Makefile.
+.ip NDBM
+If set,
+the new version of the DBM library
+that allows multiple databases will be used.
+If neither NDBM nor NEWDB are set,
+a much less efficient method of alias lookup is used.
+.ip NEWDB
+If set, use the new database package from Berkeley (from 4.4BSD).
+This package is substantially faster than DBM or NDBM.
+If NEWDB and NDBM are both set,
+sendmail will read DBM files,
+but will create and use NEWDB files.
+.ip YPCOMPAT
+If set together with
+.i both
+NEWDB and NDBM,
+.i sendmail
+will create both DBM and NEWDB files if and only if
+the file /var/yp/Makefile
+exists and is readable.
+This is intended for compatibility with Sun Microsystems'
+.i mkalias
+program used on YP masters.
+.ip _AIX3
+Compile for IBM AIX 3.x.
+This has only been tested on 3.2.3.
+.ip SYSTEM5
+Set all of the compilation parameters appropriate for System V.
+.ip LOCKF
+Use System V
+.b lockf
+instead of Berkeley
+.b flock .
+Due to the highly unusual semantics of locks
+across forks in
+.b lockf ,
+this should never be used unless absolutely necessary.
+Set by default if
+SYSTEM5 is set.
+.ip SYS5TZ
+Use System V
+time zone semantics.
+.ip HASINITGROUPS
+Set this if your system has the
+.i initgroups()
+call
+(if you have multiple group support).
+This is the default if SYSTEM5 is
+.i not
+defined or if you are on HPUX.
+.ip HASUNAME
+Set this if you have the
+.i uname (2)
+system call (or corresponding library routine).
+Set by default if
+SYSTEM5
+is set.
+.ip HASSTATFS
+Set this if you have the
+.i statfs (2)
+system call.
+This will allow you to give a temporary failure
+message to incoming SMTP email
+when you are low on disk space.
+It is set by default on 4.4 BSD and OSF/1 systems.
+.ip HASUSTAT
+Set if you have the
+.i ustat (2)
+system call.
+This is an alternative implementation of disk space control.
+You should only set one of HASSTATFS or HASUSTAT;
+the first is preferred.
+.ip _PATH_SENDMAILCF
+The pathname of the sendmail.cf file.
+.ip _PATH_SENDMAILFC
+The pathname of the sendmail.fc file.
+.ip _PATH_SENDMAILPID
+The pathname of the sendmail.pid file.
+.ip LA_TYPE
+The load average type.
+Details are described below.
+.lp
+The are four built-in ways of computing the load average.
+.i Sendmail
+tries to auto-configure them based on imperfect guesses;
+you can select one using the
+.i cc
+option
+.b \-DLA_TYPE= \c
+.i type ,
+where
+.i type
+is:
+.ip LA_INT
+The kernel stores the load average in the kernel as an array of long integers.
+The actual values are scaled by a factor FSCALE
+(default 256).
+.ip LA_FLOAT
+The kernel stores the load average in the kernel as an array of
+double precision floats.
+.ip LA_SUBR
+Call the
+.i getloadavg
+routine to get the load average as an array of doubles.
+.ip LA_ZERO
+Always return zero as the load average.
+This is the fallback case.
+.lp
+If type
+.sm LA_INT
+or
+.sm LA_FLOAT
+is specified,
+you may also need to specify
+.sm _PATH_UNIX
+(the path to your system binary)
+and
+.sm LA_AVENRUN
+(the name of the variable containing the load average in the kernel;
+usually
+.q _avenrun
+or
+.q avenrun ).
+.sh 2 "Parameters in src/conf.h"
+.pp
+Parameters and compilation options
+are defined in conf.h.
+Most of these need not normally be tweaked;
+common parameters are all in sendmail.cf.
+However, the sizes of certain primitive vectors, etc.,
+are included in this file.
+The numbers following the parameters
+are their default value.
+.nr ii 1.2i
+.ip "MAXLINE [1024]"
+The maximum line length of any input line.
+If message lines exceed this length
+they will still be processed correctly;
+however, header lines,
+configuration file lines,
+alias lines,
+etc.,
+must fit within this limit.
+.ip "MAXNAME [256]"
+The maximum length of any name,
+such as a host or a user name.
+.ip "MAXPV [40]"
+The maximum number of parameters to any mailer.
+This limits the number of recipients that may be passed in one transaction.
+It can be set to any arbitrary number above about 10,
+since
+.i sendmail
+will break up a delivery into smaller batches as needed.
+A higher number may reduce load on your system, however.
+.ip "MAXATOM [100]"
+The maximum number of atoms
+(tokens)
+in a single address.
+For example,
+the address
+.q "eric@CS.Berkeley.EDU"
+is seven atoms.
+.ip "MAXMAILERS [25]"
+The maximum number of mailers that may be defined
+in the configuration file.
+.ip "MAXRWSETS [100]"
+The maximum number of rewriting sets
+that may be defined.
+.ip "MAXPRIORITIES [25]"
+The maximum number of values for the
+.q Precedence:
+field that may be defined
+(using the
+.b P
+line in sendmail.cf).
+.ip "MAXUSERENVIRON [40]"
+The maximum number of items in the user environment
+that will be passed to subordinate mailers.
+.ip "QUEUESIZE [1000]"
+The maximum number of entries that will be processed
+in a single queue run.
+.ip "MAXMXHOSTS [20]"
+The maximum number of MX records we will accept for any single host.
+.ip "MAXIPADDR [16]"
+The maximum number of numeric IP addresses we will accept
+for this host.
+This does not limit the number the number of addresses for other hosts.
+.lp
+A number of other compilation options exist.
+These specify whether or not specific code should be compiled in.
+.nr ii 1.2i
+.ip DEBUG
+If set, debugging information is compiled in.
+To actually get the debugging output,
+the
+.b \-d
+flag must be used.
+.b "WE STRONGLY RECOMMEND THAT THIS BE LEFT ON."
+Some people, believing that it was a security hole
+(it was, once)
+have turned it off and thus crippled debuggers.
+.ip NETINET
+If set,
+support for Internet protocol networking is compiled in.
+Previous versions of
+.b sendmail
+referred to this as
+.sm DAEMON ;
+this old usage is now incorrect.
+.ip NETISO
+If set,
+support for ISO protocol networking is compiled in
+(it may be appropriate to #define this in the Makefile instead of conf.h).
+.ip LOG
+If set,
+the
+.i syslog
+routine in use at some sites is used.
+This makes an informational log record
+for each message processed,
+and makes a higher priority log record
+for internal system errors.
+.ip MATCHGECOS
+Compile in the code to do ``fuzzy matching'' on the GECOS field
+in /etc/passwd.
+This also requires that option G be turned on.
+.ip NAMED_BIND
+Compile in code to use the
+Berkeley Internet Name Domain (BIND) server
+to resolve TCP/IP host names.
+.ip NOTUNIX
+If you are using a non-UNIX mail format,
+you can set this flag to turn off special processing
+of UNIX-style
+.q "From "
+lines.
+.ip QUEUE
+This flag should be set to compile in the queueing code.
+If this is not set,
+mailers must accept the mail immediately
+or it will be returned to the sender.
+.ip SETPROCTITLE
+If defined,
+.i sendmail
+will change its
+.i argv
+array to indicate its current status.
+This can be used in conjunction with the
+.i ps
+command to find out just what it's up to.
+.ip SMTP
+If set,
+the code to handle user and server SMTP will be compiled in.
+This is only necessary if your machine has some mailer
+that speaks SMTP
+(this means most machines everywhere).
+.ip UGLYUUCP
+If you have a UUCP host adjacent to you which is not running
+a reasonable version of
+.i rmail ,
+you will have to set this flag to include the
+.q "remote from sysname"
+info on the from line.
+Otherwise, UUCP gets confused about where the mail came from.
+.ip USERDB
+Include the
+.b experimental
+Berkeley user information database package.
+This adds a new level of local name expansion
+between aliasing and forwarding.
+It also uses the NEWDB package.
+This may change in future releases.
+.ip IDENTPROTO
+Compile in the IDENT protocol as defined in RFC 1413.
+This defaults on for all systems except Ultrix,
+which apparently has the interesting
+.q feature
+that when it receives a
+.q "host unreachable"
+message it closes all open connections to that host.
+Since some firewall gateways send this error code
+when you access an unauthorized port (such as 113, used by IDENT),
+Ultrix cannot receive email from such hosts.
+.sh 2 "Configuration in src/conf.c"
+.pp
+The following changes can be made in conf.c.
+.sh 3 "Built-in Header Semantics"
+.pp
+Not all header semantics are defined in the configuration file.
+Header lines that should only be included by certain mailers
+(as well as other more obscure semantics)
+must be specified in the
+.i HdrInfo
+table in
+.i conf.c .
+This table contains the header name
+(which should be in all lower case)
+and a set of header control flags (described below),
+The flags are:
+.ip H_ACHECK
+Normally when the check is made to see if a header line is compatible
+with a mailer,
+.i sendmail
+will not delete an existing line.
+If this flag is set,
+.i sendmail
+will delete
+even existing header lines.
+That is,
+if this bit is set and the mailer does not have flag bits set
+that intersect with the required mailer flags
+in the header definition in
+sendmail.cf,
+the header line is
+.i always
+deleted.
+.ip H_EOH
+If this header field is set,
+treat it like a blank line,
+i.e.,
+it will signal the end of the header
+and the beginning of the message text.
+.ip H_FORCE
+Add this header entry
+even if one existed in the message before.
+If a header entry does not have this bit set,
+.i sendmail
+will not add another header line if a header line
+of this name already existed.
+This would normally be used to stamp the message
+by everyone who handled it.
+.ip H_TRACE
+If set,
+this is a timestamp
+(trace)
+field.
+If the number of trace fields in a message
+exceeds a preset amount
+the message is returned
+on the assumption that it has an aliasing loop.
+.ip H_RCPT
+If set,
+this field contains recipient addresses.
+This is used by the
+.b \-t
+flag to determine who to send to
+when it is collecting recipients from the message.
+.ip H_FROM
+This flag indicates that this field
+specifies a sender.
+The order of these fields in the
+.i HdrInfo
+table specifies
+.i sendmail's
+preference
+for which field to return error messages to.
+.nr ii 5n
+.lp
+Let's look at a sample
+.i HdrInfo
+specification:
+.(b
+.ta 4n +\w'"return-receipt-to",  'u
+struct hdrinfo HdrInfo[] =
+\&{
+            /* originator fields, most to least significant  */
+       "resent-sender",        H_FROM,
+       "resent-from",  H_FROM,
+       "sender",       H_FROM,
+       "from", H_FROM,
+       "full-name",    H_ACHECK,
+            /* destination fields */
+       "to",   H_RCPT,
+       "resent-to",    H_RCPT,
+       "cc",   H_RCPT,
+            /* message identification and control */
+       "message",      H_EOH,
+       "text", H_EOH,
+            /* trace fields */
+       "received",     H_TRACE|H_FORCE,
+
+       NULL,   0,
+};
+.)b
+This structure indicates that the
+.q To: ,
+.q Resent-To: ,
+and
+.q Cc:
+fields
+all specify recipient addresses.
+Any
+.q Full-Name:
+field will be deleted unless the required mailer flag
+(indicated in the configuration file)
+is specified.
+The
+.q Message:
+and
+.q Text:
+fields will terminate the header;
+these are used by random dissenters around the network world.
+The
+.q Received:
+field will always be added,
+and can be used to trace messages.
+.pp
+There are a number of important points here.
+First,
+header fields are not added automatically just because they are in the
+.i HdrInfo
+structure;
+they must be specified in the configuration file
+in order to be added to the message.
+Any header fields mentioned in the configuration file but not
+mentioned in the
+.i HdrInfo
+structure have default processing performed;
+that is,
+they are added unless they were in the message already.
+Second,
+the
+.i HdrInfo
+structure only specifies cliched processing;
+certain headers are processed specially by ad hoc code
+regardless of the status specified in
+.i HdrInfo .
+For example,
+the
+.q Sender:
+and
+.q From:
+fields are always scanned on ARPANET mail
+to determine the sender\**;
+.(f
+\**Actually, this is no longer true in SMTP;
+this information is contained in the envelope.
+The older ARPANET protocols did not completely distinguish
+envelope from header.
+.)f
+this is used to perform the
+.q "return to sender"
+function.
+The
+.q "From:"
+and
+.q "Full-Name:"
+fields are used to determine the full name of the sender
+if possible;
+this is stored in the macro
+.b $x
+and used in a number of ways.
+.sh 3 "Restricting Use of Email"
+.pp
+If it is necessary to restrict mail through a relay,
+the
+.i checkcompat
+routine can be modified.
+This routine is called for every recipient address.
+It returns an exit status
+indicating the status of the message.
+The status
+.sm EX_OK
+accepts the address,
+.sm EX_TEMPFAIL
+queues the message for a later try,
+and other values
+(commonly
+.sm EX_UNAVAILABLE )
+reject the message.
+It is up to
+.i checkcompat
+to print an error message
+(using
+.i usrerr )
+if the message is rejected.
+For example,
+.i checkcompat
+could read:
+.(b
+.re
+.sz -1
+.ta 4n +4n +4n +4n +4n +4n +4n
+int
+checkcompat(to, e)
+       register ADDRESS *to;
+       register ENVELOPE *e;
+\&{
+       register STAB *s;
+
+       s = stab("private", ST_MAILER, ST_FIND);
+       if (s != NULL && e\->e_from.q_mailer != LocalMailer &&
+           to->q_mailer == s->s_mailer)
+       {
+               usrerr("No private net mail allowed through this machine");
+               return (EX_UNAVAILABLE);
+       }
+       if (MsgSize > 50000 && to\->q_mailer != LocalMailer)
+       {
+               usrerr("Message too large for non-local delivery");
+               NoReturn = TRUE;
+               return (EX_UNAVAILABLE);
+       }
+       return (EX_OK);
+}
+.sz
+.)b
+This would reject messages greater than 50000 bytes
+unless they were local.
+The
+.i NoReturn
+flag can be sent to suppress the return of the actual body
+of the message in the error return.
+The actual use of this routine is highly dependent on the
+implementation,
+and use should be limited.
+.sh 3 "Load Average Computation"
+.pp
+The routine
+.i getla
+should return an approximation of the current system load average
+as an integer.
+There are four versions included on compilation flags
+as described above.
+.sh 3 "New Database Map Classes"
+.pp
+New key maps can be added by creating a class initialization function
+and a lookup function.
+These are then added to the routine
+.i setupmaps.
+.pp
+The initialization function is called as
+.(b
+\fIxxx\fP_map_init(MAP *map, char *mapname, char *args)
+.)b
+The
+.i map
+is an internal data structure.
+The
+.i mapname
+is the name of the map (used for error messages).
+The
+.i args
+is a pointer to the rest of the configuration file line;
+flags and filenames can be extracted from this line.
+The initialization function must return
+.sm TRUE
+if it successfully opened the map,
+.sm FALSE
+otherwise.
+.pp
+The lookup function is called as
+.(b
+\fIxxx\fP_map_lookup(MAP *map, char buf[], int bufsize, char **av, int *statp)
+.)b
+The
+.i map
+defines the map internally.
+The parameters
+.i buf
+and
+.i bufsize
+have the input key.
+This may be (and often is) used destructively.
+The
+.i av
+is a list of arguments passed in from the rewrite line.
+The lookup function should return a pointer to the new value.
+IF the map lookup fails,
+.i *statp
+should be set to an exit status code;
+in particular, it should be set to
+.sm EX_TEMPFAIL
+if recovery is to be attempted by the higher level code.
+.sh 3 "Queueing Function"
+.pp
+The routine
+.i shouldqueue
+is called to decide if a message should be queued
+or processed immediately.
+Typically this compares the message priority to the current load average.
+The default definition is:
+.(b
+bool
+shouldqueue(pri, ctime)
+       long pri;
+       time_t ctime;
+{
+       if (CurrentLA < QueueLA)
+               return (FALSE);
+       if (CurrentLA >= RefuseLA)
+               return (TRUE);
+       return (pri > (QueueFactor / (CurrentLA \- QueueLA + 1)));
+}
+.)b
+If the current load average
+(global variable
+.i CurrentLA ,
+which is set before this function is called)
+is less than the low threshold load average
+(option
+.b x ,
+variable
+.i QueueLA ),
+.i shouldqueue
+returns
+.sm FALSE
+immediately
+(that is, it should
+.i not
+queue).
+If the current load average exceeds the high threshold load average
+(option
+.b X ,
+variable
+.i RefuseLA ),
+.i shouldqueue
+returns
+.sm TRUE
+immediately.
+Otherwise, it computes the function based on the message priority,
+the queue factor
+(option
+.b q ,
+global variable
+.i QueueFactor ),
+and the current and threshold load averages.
+.pp
+An implementation wishing to take the actual age of the message into account
+can also use the
+.i ctime
+parameter,
+which is the time that the message was first submitted to
+.i sendmail .
+Note that the
+.i pri
+parameter is already weighted
+by the number of times the message has been tried
+(although this tends to lower the priority of the message with time);
+the expectation is that the
+.i ctime
+would be used as an
+.q "escape clause"
+to ensure that messages are eventually processed.
+.sh 3 "Refusing Incoming SMTP Connections"
+.pp
+The function
+.i refuseconnections
+returns
+.sm TRUE
+if incoming SMTP connections should be refused.
+The current implementation is based exclusively on the current load average
+and the refuse load average option
+(option
+.b X ,
+global variable
+.i RefuseLA ):
+.(b
+bool
+refuseconnections()
+{
+       return (CurrentLA >= RefuseLA);
+}
+.)b
+A more clever implementation
+could look at more system resources.
+.sh 3 "Load Average Computation"
+.pp
+The routine
+.i getla
+returns the current load average (as a rounded integer).
+The distribution includes several possible implementations.
+.sh 2 "Configuration in src/daemon.c"
+.pp
+The file
+.i src/daemon.c
+contains a number of routines that are dependent
+on the local networking environment.
+The version supplied is specific to 4.3 BSD.
+.pp
+In previous releases,
+we recommended that you modify the routine
+.i maphostname
+if you wanted to generalize
+.b $[
+\&...\&
+.b $]
+lookups.
+We now recommend that you create a new keyed map instead.
+.sh 1 "CHANGES IN VERSION 6"
+.pp
+The following summarizes changes
+since the last commonly available version of
+.b sendmail
+(5.67):
+.sh 2 "Connection Caching"
+.pp
+Instead of closing SMTP connections immediately,
+those connections are cached for possible future use.
+The advent of MX records made this effective for mailing lists;
+in addition,
+substantial performance improvements can be expected for queue processing.
+.sh 2 "MX Piggybacking"
+.pp
+If two hosts with different names in a single message
+happen to have the same set of MX hosts,
+they can be sent in the same transaction.
+Version 6 notices this and tries to batch the messages.
+.sh 2 "Eight-Bit Clean"
+.pp
+Previous versions of
+.b sendmail
+used the 0200 bit for quoting.
+This version avoids that use.
+However, for compatibility with RFC 822,
+you can set option `7' to get seven bit stripping.
+.pp
+Individual mailers can still produce seven bit out put using the
+`7' mailer flag.
+.sh 2 "User Database"
+.pp
+The user database is an as-yet experimental attempt
+to provide unified large-site name support.
+We are installing it at Berkeley;
+future versions may show significant modifications.
+.sh 2 "Improved BIND Support"
+.pp
+The BIND support,
+particularly for MX records,
+had a number of annoying
+.q features
+which have been removed in this release.
+In particular,
+these more tightly bind (pun intended) the name server to sendmail,
+so that the name server resolution rules are incorporated directly into
+.b sendmail .
+.sh 2 "Keyed Files"
+.pp
+Generalized keyed files is an idea taken directly from
+.sm IDA
+.b sendmail
+(albeit with a completely different implementation).
+They can be useful on large sites.
+.pp
+R6 also understands YP.
+.sh 2 "Multi-Word Classes"
+.pp
+Classes can now be multiple words.
+For example,
+.(b
+CShofmann.CS.Berkeley.EDU
+.)b
+allows you to match the entire string
+.q hofmann.CS.Berkeley.EDU
+using the single construct
+.q $=S .
+.sh 2 "Deferred Macro Expansion"
+.pp
+The
+.b $& \c
+.i x
+construct has been adopted from
+.sm IDA .
+.sh 2 "IDENT Protocol Support"
+.pp
+The IDENT protocol as defined in RFC 1413 is supported.
+.sh 2 "Parsing Bug Fixes"
+.pp
+A number of small bugs having to do with things like
+backslash-escaped quotes inside of comments
+have been fixed.
+.sh 2 "Separate Envelope/Header Processing"
+.pp
+Since the From: line is passed in separately from the envelope sender,
+these have both been made visible;
+the
+.b $g
+macro is set to the envelope sender during processing
+of mailer argument vectors
+and the header sender during processing of headers.
+.pp
+It is also possible to specify separate per-mailer
+envelope and header processing.
+The
+.b S enderRWSet
+and
+.b R ecipientRWset
+arguments for mailers
+can be specified as
+.i envelope/header
+to give different rewritings for envelope versus header addresses.
+.sh 2 "Owner-List Propagates to Envelope"
+.pp
+When an alias has an associated owner\-list name,
+that alias is used to change the envelope sender address.
+This will cause downstream errors to be returned to that owner.
+.sh 2 "Dynamic Header Allocation"
+.pp
+The fixed size limit on header lines has been eliminated.
+.sh 2 "New Command Line Flag"
+.pp
+The \-p flag has been added
+to pass in protocol information.
+.sh 2 "New and Old Configuration Line Types"
+.pp
+The
+.b T
+(Trusted users) configuration line has been deleted.
+It will still be accepted but will be ignored.
+.pp
+The
+.b K
+line has been added to declare database maps.
+.pp
+The
+.b V
+line has been added to declare the configuration version level.
+.sh 2 "New Options"
+.pp
+Several new options have been added,
+many to support new features,
+others to allow tuning that was previously available
+only by recompiling.
+They are described in detail in Section 5.1.5.
+Briefly,
+.ip b
+Insist on a minimum number of disk blocks.
+.ip C
+Set checkpoint interval.
+.ip E
+Default error message.
+.ip G
+Enable GECOS matching.
+.ip h
+Maximum hop count.
+.ip j
+Send errors in MIME-encapsulated format.
+.ip J
+Forward file path.
+.ip k
+Connection cache size
+.ip K
+Connection cache lifetime.
+.ip l
+Enable Errors-To: header.
+These headers violate RFC 1123;
+this option is included to provide back compatibility
+with old versions of sendmail.
+.ip p
+Privacy options.
+.ip U
+User database spec.
+.ip 7
+Do not run eight bit clean.
+.sh 2 "Extended Options"
+.pp
+The
+.b r
+(read timeout),
+.b I
+(use BIND),
+and
+.b T
+(queue timeout)
+options have been extended to pass in more information.
+.sh 2 "New Mailer Flag"
+.pp
+The
+.b c
+mailer flag will strip all comments
+from addresses;
+this should only be used as a last resort
+when dealing with cranky mailers.
+.sh 2 "New LHS Token"
+.pp
+Version 6 allows
+.b $@
+on the Left Hand Side of an
+.q R
+line to match zero tokens.
+This is intended to be used to match the null input.
+.sh 2 "Bigger Defaults"
+.pp
+Version 6 allows up to 100 rulesets instead of 30.
+It is recommended that rulesets 0\-9 be reserved for
+.i sendmail 's
+dedicated use in future releases.
+.pp
+The total number of MX records that can be used has been raised to 20.
+.pp
+The number of queued messages that can be handled at one time
+has been raised from 600 to 1000.
+.sh 2 "Different Default Tuning Parameters"
+.pp
+Version 6 has changed the default parameters
+for tuning queue costs
+to make the number of recipients more important
+than the size of the message (for small messages).
+This is reasonable if you are connected with reasonably fast links.
+.sh 2 "Auto-Quoting in Addresses"
+.pp
+Previously, the
+.q "Full Name <email address>"
+syntax would generate incorrect protocol output
+if
+.q "Full Name"
+had special characters such as dot.
+This version puts quotes around such names.
+.sh 2 "Symbolic Names On Error Mailer"
+.pp
+Several names have been built in to the $@ portion of the $#error
+mailer.
+.sh 2 "SMTP VRFY Doesn't Expand"
+.pp
+Previous versions of
+.i sendmail
+treated VRFY and EXPN the same.
+In this version,
+VRFY doesn't expand aliases or follow .forward files.
+.pp
+As an optimization, if you run with your default delivery mode being
+queue-only,
+the RCPT command will also not chase aliases and .forward files.
+It will chase them when it processes the queue.
+.sh 2 "[IPC] Mailers Allow Multiple Hosts"
+.pp
+When an address resolves to a mailer that has
+.q [IPC]
+as its
+.q Path ,
+the $@ part (host name)
+can be a colon-separated list of hosts instead of a single hostname.
+This asks sendmail to search the list for the first entry that is available
+exactly as though it were an MX record.
+The intent is to route internal traffic through internal networks
+without publishing an MX record to the net.
+MX expansion is still done on the individual items.
+.sh 2 "Aliases Extended"
+.pp
+The implementation has been merged with maps.
+Among other things,
+this supports NIS-based aliases.
+.sh 2 "Portability and Security Enhancements"
+.pp
+A number of internal changes have been made to enhance portability.
+.pp
+Several fixes have been made to increase the paranoia factor.
+.sh 1 "ACKNOWLEDGEMENTS"
+.pp
+I've worked on
+.i sendmail
+for many years,
+and many employers have been remarkably patient
+about letting me work on a large project
+that was not part of my official job.
+This includes time on the INGRES Project at Berkeley,
+at Britton Lee,
+and again on the Mammoth Project at Berkeley.

+Much of the second wave of improvements
+should be credited to Bryan Costales of ICSI.
+As he passed me drafts of his book on
+.i sendmail
+I was inspired to start working on things again.
+Bryan was also available to bounce ideas off of.
+.pp
+Many, many people contributed chunks of code and ideas to
+.i sendmail .
+It has proven to be a group network effort.
+Version 6 in particular was a group project.
+The following people made notable contributions:
+.(l
+Keith Bostic, CSRG, University of California, Berkeley
+Michael J. Corrigan, University of California, San Diego
+Bryan Costales, International Computer Science Institute
+P{r (Pell) Emanuelsson
+Craig Everhart, Transarc Corporation
+Tom Ivar Helbekkmo, Norwegian School of Economics
+Allan E. Johannesen, WPI
+Takahiro Kanbe, FujiXerox
+Brian Kantor, University of California, San Diego
+Bruce Lilly, Sony U.S.
+Nakamura Motonori, Kyoto University
+John Gardiner Myers, Carnegie Mellon University
+Neil Rickert, Northern Illinois University
+Eric Wassenaar, National Institute for Nuclear and High Energy Physics, Amsterdam
+Christophe Wolfhugel, Herve Schauer Consultants (Paris)
+.)l
+I apologize for anyone I have omitted, misspelled, misattributed, or
+otherwise missed.
+Many other people have contributed ideas, comments, and encouragement.
+I appreciate their contribution as well.

+.+c "COMMAND LINE FLAGS"
+.ba 0
+.nr ii 1i
+.pp
+Arguments must be presented with flags before addresses.
+The flags are:
+.ip \-b\fIx\fP
+Set operation mode to
+.i x .
+Operation modes are:
+.(b
+.ta 4n
+m      Deliver mail (default)
+s      Speak SMTP on input side
+d      Run as a daemon
+t      Run in test mode
+v      Just verify addresses, don't collect or deliver
+i      Initialize the alias database
+p      Print the mail queue
+z      Freeze the configuration file
+.)b
+.ip \-C\fIfile\fP
+Use a different configuration file.
+.i Sendmail
+runs as the invoking user (rather than root)
+when this flag is specified.
+.ip \-d\fIlevel\fP
+Set debugging level.
+.ip "\-f\ \fIaddr\fP"
+The sender's machine address is
+.i addr .
+.ip \-F\fIname\fP
+Sets the full name of this user to
+.i name .
+.ip "\-h\ \fIcnt\fP"
+Sets the
+.q "hop count"
+to
+.i cnt .
+This represents the number of times this message has been processed
+by
+.i sendmail
+(to the extent that it is supported by the underlying networks).
+.i Cnt
+is incremented during processing,
+and if it reaches
+MAXHOP
+(currently 30)
+.i sendmail
+throws away the message with an error.
+.ip \-n
+Don't do aliasing or forwarding.
+.ip "\-r\ \fIaddr\fP"
+An obsolete form of
+.b \-f .
+.ip \-o\fIx\|value\fP
+Set option
+.i x
+to the specified
+.i value .
+These options are described in Appendix B.
+.ip \-p\fIprotocol\fP
+Set the sending protocol.
+Programs are encouraged to set this.
+The protocol field can be in the form
+.i protocol \c
+.b : \c
+.i host
+to set both the sending protocol and sending host.
+For example,
+.q \-pUUCP:uunet
+sets the sending protocol to UUCP
+and the sending host to uunet.
+(Some existing programs use \-oM to set the r and s macros;
+this is equivalent to using \-p.)
+.ip \-q\fItime\fP
+Try to process the queued up mail.
+If the time is given,
+a sendmail will run through the queue at the specified interval
+to deliver queued mail;
+otherwise, it only runs once.
+.ip \-q\fIXstring\fP
+Run the queue once,
+limiting the jobs to those matching
+.i Xstring .
+The key letter
+.i X
+can be
+.b I
+to limit based on queue identifier,
+.b R
+to limit based on recipient,
+or
+.b S
+to limit based on sender.
+A particular queued job is accepted if one of the corresponding addresses
+contains the indicated
+.i string .
+.ip \-t
+Read the header for
+.q To: ,
+.q Cc: ,
+and
+.q Bcc:
+lines, and send to everyone listed in those lists.
+The
+.q Bcc:
+line will be deleted before sending.
+Any addresses in the argument vector will be deleted
+from the send list.
+.pp
+There are a number of options that may be specified as
+primitive flags
+(provided for compatibility with
+.i delivermail ).
+These are the e, i, m, and v options.
+Also,
+the f option
+may be specified as the
+.b \-s
+flag.
+.+c "QUEUE FILE FORMATS"
+.pp
+This appendix describes the format of the queue files.
+These files live in the directory defined by the
+.b Q
+option in the
+.i sendmail.cf
+file, usually
+.i /var/spool/mqueue
+or
+.i /usr/spool/mqueue .
+.pp
+All queue files have the name
+\fIx\fP\|\fBf\fP\fIAAA99999\fP
+where
+.i AAA99999
+is the
+.i id
+for this message
+and the
+.i x
+is a type.
+The first letter of the id encodes the hour of the day
+that the message was received by the system
+(with A being the hour between midnight and 1:00AM).
+All files with the same id collectively define one message.
+.pp
+The types are:
+.nr ii 0.5i
+.ip d
+The data file.
+The message body (excluding the header) is kept in this file.
+.ip l
+The lock file.
+If this file exists,
+the job is currently being processed,
+and a queue run will not process the file.
+For that reason,
+an extraneous
+.b lf
+file can cause a job to apparently disappear
+(it will not even time out!).
+[Actually, this file is obsolete on most systems that support the
+.b flock
+or
+.b lockf
+system calls.]
+.ip n
+This file is created when an id is being created.
+It is a separate file to insure that no mail can ever be destroyed
+due to a race condition.
+It should exist for no more than a few milliseconds
+at any given time.
+[This is only used on old versions of
+sendmail;
+it is not used 
+on newer versions.]
+.ip q
+The queue control file.
+This file contains the information necessary to process the job.
+.ip t
+A temporary file.
+These are an image of the
+.b qf
+file when it is being rebuilt.
+It should be renamed to a
+.b qf
+file very quickly.
+.ip x
+A transcript file,
+existing during the life of a session
+showing everything that happens
+during that session.
+.pp
+The
+.b qf
+file is structured as a series of lines
+each beginning with a code letter.
+The lines are as follows:
+.ip D
+The name of the data file.
+There may only be one of these lines.
+.ip H
+A header definition.
+There may be any number of these lines.
+The order is important:
+they represent the order in the final message.
+These use the same syntax
+as header definitions in the configuration file.
+.ip C
+The controlling address.
+The syntax is
+.q localuser:aliasname .
+Recipient addresses following this line
+will be flagged so that deliveries will be run as the
+.i localuser
+(a user name from the /etc/passwd file);
+.i aliasname
+is the name of the alias that expanded to this address
+(used for printing messages).
+.ip R
+A recipient address.
+This will normally be completely aliased,
+but is actually realiased when the job is processed.
+There will be one line
+for each recipient.
+.ip S
+The sender address.
+There may only be one of these lines.
+.ip E
+An error address.
+If any such lines exist,
+they represent the addresses that should receive error messages.
+.ip T
+The job creation time.
+This is used to compute when to time out the job.
+.ip P
+The current message priority.
+This is used to order the queue.
+Higher numbers mean lower priorities.
+The priority changes
+as the message sits in the queue.
+The initial priority depends on the message class
+and the size of the message.
+.ip M
+A message.
+This line is printed by the
+.i mailq
+command,
+and is generally used to store status information.
+It can contain any text.
+.ip F
+Flag bits, represented as one letter per flag.
+Defined flag bits are
+.b r
+indicating that this is a response message
+and
+.b w
+indicating that a warning message has been sent
+announcing that the mail has been delayed.
+.ip $
+A macro definition.
+The values of certain macros
+(as of this writing, only
+.b $r
+and
+.b $s )
+are passed through to the queue run phase.
+.ip B
+The body type.
+The remainder of the line is a text string defining the body type.
+If this field is missing,
+the body type is assumed to be
+.q "undefined"
+and no special processing is attempted.
+Legal values are
+.q 7BIT
+and
+.q 8BITMIME .
+.pp
+As an example,
+the following is a queue file sent to
+.q eric@mammoth.Berkeley.EDU
+and
+.q bostic@okeeffe.CS.Berkeley.EDU \**:
+.(f
+\**This example is contrived and probably inaccurate for your environment.
+Glance over it to get an idea;
+nothing can replace looking at what your own system generates.

+.+c "SUMMARY OF SUPPORT FILES"
+.pp
+This is a summary of the support files
+that
+.i sendmail
+creates or generates.
+Many of these can be changed by editing the sendmail.cf file;

+.ip "/usr/\*(SD/sendmail"
+The binary of
+.i sendmail .
+.ip /usr/bin/newaliases
+A link to /usr/\*(SD/sendmail;
+causes the alias database to be rebuilt.
+Running this program is completely equivalent to giving
+.i sendmail
+the
+.b \-bi
+flag.
+.ip /usr/bin/mailq
+Prints a listing of the mail queue.
+This program is equivalent to using the
+.b \-bp
+flag to

+.ip /etc/sendmail.st
+A statistics file; need not be present.
+.ip /etc/sendmail.pid
+Created in daemon mode;
+it contains the process id of the current SMTP daemon.
+If you use this in scripts;
+use ``head \-1'' to get just the first line;
+later versions of
+.i sendmail
+may add information to subsequent lines.
+.ip /etc/aliases
+The textual version of the alias file.
+.ip /etc/aliases.{pag,dir}
+The alias file in
+.i dbm \|(3)
+format.
+.ip /var/spool/mqueue

+Routing mail through a heterogeneous internet presents many new

+Sendmail will replace delivermail in the Berkeley 4.2 distribution.

+gateway.
+The changes that will be user visible are emphasized.

+.sp 2
+.(f
+\(dgA considerable part of this work
+was done while under the employ
+of the INGRES Project
+at the University of California at Berkeley.
+.)f
+.pp
+The mail system to appear in 4.2bsd
+will contain a number of changes.
+Most of these changes are based on the replacement of
+.i delivermail
+with a new module called
+.i sendmail.
+.i Sendmail
+implements a general internetwork mail routing facility,
+featuring aliasing and forwarding,
+automatic routing to network gateways,
+and flexible configuration.
+Of key interest to the mail system user
+will be the changes in the network addressing structure.
+.pp
+In a simple network,
+each node has an address,
+and resources can be identified
+with a host-resource pair;
+in particular,
+the mail system can refer to users
+using a host-username pair.
+Host names and numbers have to be administered by a central authority,
+but usernames can be assigned locally to each host.
+.pp
+In an internet,
+multiple networks with different characteristics
+and managements
+must communicate.
+In particular,
+the syntax and semantics of resource identification change.
+Certain special cases can be handled trivially
+by
+.i "ad hoc"
+techniques,
+such as
+providing network names that appear local to hosts
+on other networks,
+as with the Ethernet at Xerox PARC.
+However, the general case is extremely complex.
+For example,
+some networks require that the route the message takes
+be explicitly specified by the sender,
+simplifying the database update problem
+since only adjacent hosts must be entered
+into the system tables,
+while others use logical addressing,
+where the sender specifies the location of the recipient
+but not how to get there.
+Some networks use a left-associative syntax
+and others use a right-associative syntax,
+causing ambiguity in mixed addresses.
+.pp
+Internet standards seek to eliminate these problems.
+Initially, these proposed expanding the address pairs
+to address triples,
+consisting of
+{network, host, username}
+triples.
+Network numbers must be universally agreed upon,
+and hosts can be assigned locally
+on each network.
+The user-level presentation was changed
+to address domains,
+comprised of a local resource identification
+and a hierarchical domain specification
+with a common static root.
+The domain technique
+separates the issue of physical versus logical addressing.
+For example,
+an address of the form
+.q "eric@a.cc.berkeley.arpa"
+describes the logical
+organization of the address space
+(user
+.q eric
+on host
+.q a
+in the Computer Center
+at Berkeley)
+but not the physical networks used
+(for example, this could go over different networks
+depending on whether
+.q a
+were on an ethernet
+or a store-and-forward network).
+.pp
+.i Sendmail
+is intended to help bridge the gap
+between the totally
+.i "ad hoc"
+world
+of networks that know nothing of each other
+and the clean, tightly-coupled world
+of unique network numbers.
+It can accept old arbitrary address syntaxes,
+resolving ambiguities using heuristics
+specified by the system administrator,
+as well as domain-based addressing.
+It helps guide the conversion of message formats
+between disparate networks.
+In short,
+.i sendmail
+is designed to assist a graceful transition
+to consistent internetwork addressing schemes.
+.sp
+.pp
+Section 1 defines some of the terms
+frequently left fuzzy
+when working in mail systems.
+Section 2 discusses the design goals for
+.i sendmail .
+In section 3,
+the new address formats
+and basic features of
+.i sendmail
+are described.
+Section 4 discusses some of the special problems
+of the UUCP network.
+The differences between
+.i sendmail
+and
+.i delivermail
+are presented in section 5.

+.(l F
+.b DISCLAIMER:
+A number of examples
+in this paper
+use names of actual people
+and organizations.
+This is not intended
+to imply a commitment
+or even an intellectual agreement
+on the part of these people or organizations.
+In particular,
+Bell Telephone Laboratories (BTL),
+Digital Equipment Corporation (DEC),
+Lawrence Berkeley Laboratories (LBL),
+Britton-Lee Incorporated (BLI),
+and the University of California at Berkeley
+are not committed to any of these proposals at this time.
+Much of this paper
+represents no more than
+the personal opinions of the author.
+.)l
+.sh 1 "DEFINITIONS"
+.pp
+There are four basic concepts
+that must be clearly distinguished
+when dealing with mail systems:
+the user (or the user's agent),
+the user's identification,
+the user's address,
+and the route.
+These are distinguished primarily by their position independence.
+.sh 2 "User and Identification"
+.pp
+The user is the being
+(a person or program)
+that is creating or receiving a message.
+An
+.i agent
+is an entity operating on behalf of the user \*-
+such as a secretary who handles my mail.
+or a program that automatically returns a
+message such as
+.q "I am at the UNICOM conference."
+.pp
+The identification is the tag
+that goes along with the particular user.
+This tag is completely independent of location.
+For example,
+my identification is the string
+.q "Eric Allman,"
+and this identification does not change
+whether I am located at U.C. Berkeley,
+at Britton-Lee,
+or at a scientific institute in Austria.
+.pp
+Since the identification is frequently ambiguous
+(e.g., there are two
+.q "Robert Henry" s
+at Berkeley)
+it is common to add other disambiguating information
+that is not strictly part of the identification
+(e.g.,
+Robert
+.q "Code Generator"
+Henry
+versus
+Robert
+.q "System Administrator"
+Henry).
+.sh 2 "Address"
+.pp
+The address specifies a location.
+As I move around,
+my address changes.
+For example,
+my address might change from
+.q eric@Berkeley.ARPA
+to
+.q eric@bli.UUCP
+or
+.q allman@IIASA.Austria
+depending on my current affiliation.
+.pp
+However,
+an address is independent of the location of anyone else.
+That is,
+my address remains the same to everyone who might be sending me mail.
+For example,
+a person at MIT and a person at USC
+could both send to
+.q eric@Berkeley.ARPA
+and have it arrive to the same mailbox.
+.pp
+Ideally a
+.q "white pages"
+service would be provided to map user identifications
+into addresses
+(for example, see
+[Solomon81]).
+Currently this is handled by passing around
+scraps of paper
+or by calling people on the telephone
+to find out their address.
+.sh 2 "Route"
+.pp
+While an address specifies
+.i where
+to find a mailbox,
+a route specifies
+.i how
+to find the mailbox.
+Specifically,
+it specifies a path
+from sender to receiver.
+As such, the route is potentially different
+for every pair of people in the electronic universe.
+.pp
+Normally the route is hidden from the user
+by the software.
+However,
+some networks put the burden of determining the route
+onto the sender.
+Although this simplifies the software,
+it also greatly impairs the usability
+for most users.
+The UUCP network is an example of such a network.
+.sh 1 "DESIGN GOALS"
+.pp
+Design goals for
+.i sendmail \**
+.(f
+\**This section makes no distinction between
+.i delivermail
+and
+.i sendmail.
+.)f
+include:
+.np
+Compatibility with the existing mail programs,
+including Bell version 6 mail,
+Bell version 7 mail,
+Berkeley
+.i Mail
+[Shoens79],
+BerkNet mail
+[Schmidt79],
+and hopefully UUCP mail
+[Nowitz78].
+ARPANET mail
+[Crocker82]
+was also required.
+.np
+Reliability, in the sense of guaranteeing
+that every message is correctly delivered
+or at least brought to the attention of a human
+for correct disposal;
+no message should ever be completely lost.
+This goal was considered essential
+because of the emphasis on mail in our environment.
+It has turned out to be one of the hardest goals to satisfy,
+especially in the face of the many anomalous message formats
+produced by various ARPANET sites.
+For example,
+certain sites generate improperly formated addresses,
+occasionally
+causing error-message loops.
+Some hosts use blanks in names,
+causing problems with
+mail programs that assume that an address
+is one word.
+The semantics of some fields
+are interpreted slightly differently
+by different sites.
+In summary,
+the obscure features of the ARPANET mail protocol
+really
+.i are
+used and
+are difficult to support,
+but must be supported.
+.np
+Existing software to do actual delivery
+should be used whenever possible.
+This goal derives as much from political and practical considerations
+as technical.
+.np
+Easy expansion to
+fairly complex environments,
+including multiple
+connections to a single network type
+(such as with multiple UUCP or Ethernets).
+This goal requires consideration of the contents of an address
+as well as its syntax
+in order to determine which gateway to use.
+.np
+Configuration information should not be compiled into the code.
+A single compiled program should be able to run as is at any site
+(barring such basic changes as the CPU type or the operating system).
+We have found this seemingly unimportant goal
+to be critical in real life.
+Besides the simple problems that occur when any program gets recompiled
+in a different environment,
+many sites like to
+.q fiddle
+with anything that they will be recompiling anyway.
+.np
+.i Sendmail
+must be able to let various groups maintain their own mailing lists,
+and let individuals specify their own forwarding,
+without modifying the system alias file.
+.np
+Each user should be able to specify which mailer to execute
+to process mail being delivered for him.
+This feature allows users who are using specialized mailers
+that use a different format to build their environment
+without changing the system,
+and facilitates specialized functions
+(such as returning an
+.q "I am on vacation"
+message).
+.np
+Network traffic should be minimized
+by batching addresses to a single host where possible,
+without assistance from the user.
+.pp
+These goals motivated the architecture illustrated in figure 1.

+The user interacts with a mail generating and sending program.
+When the mail is created,
+the generator calls
+.i sendmail ,
+which routes the message to the correct mailer(s).
+Since some of the senders may be network servers
+and some of the mailers may be network clients,
+.i sendmail
+may be used as an internet mail gateway.
+.sh 1 "USAGE"
+.sh 2 "Address Formats"
+.pp
+Arguments may be flags or addresses.
+Flags set various processing options.
+Following flag arguments,
+address arguments may be given.
+Addresses follow the syntax in RFC822
+[Crocker82]
+for ARPANET
+address formats.
+In brief, the format is:
+.np
+Anything in parentheses is thrown away
+(as a comment).
+.np
+Anything in angle brackets (\c
+.q "<\|>" )
+is preferred
+over anything else.
+This rule implements the ARPANET standard that addresses of the form
+.(b
+user name <machine-address>
+.)b
+will send to the electronic
+.q machine-address
+rather than the human
+.q "user name."
+.np
+Double quotes
+(\ "\ )
+quote phrases;
+backslashes quote characters.
+Backslashes are more powerful
+in that they will cause otherwise equivalent phrases
+to compare differently \*- for example,
+.i user
+and
+.i
+"user"
+.r
+are equivalent,
+but
+.i \euser
+is different from either of them.
+This might be used
+to avoid normal aliasing
+or duplicate suppression algorithms.
+.pp
+Parentheses, angle brackets, and double quotes
+must be properly balanced and nested.
+The rewriting rules control remaining parsing\**.
+.(f
+\**Disclaimer: Some special processing is done
+after rewriting local names; see below.
+.)f
+.pp
+Although old style addresses are still accepted
+in most cases,
+the preferred address format
+is based on ARPANET-style domain-based addresses
+[Su82a].
+These addresses are based on a hierarchical, logical decomposition
+of the address space.
+The addresses are hierarchical in a sense
+similar to the U.S. postal addresses:
+the messages may first be routed to the correct state,
+with no initial consideration of the city
+or other addressing details.
+The addresses are logical
+in that each step in the hierarchy
+corresponds to a set of
+.q "naming authorities"
+rather than a physical network.
+.pp
+For example,
+the address:
+.(l
+eric@HostA.BigSite.ARPA
+.)l
+would first look up the domain
+BigSite
+in the namespace administrated by
+ARPA.
+A query could then be sent to
+BigSite
+for interpretation of
+HostA.
+Eventually the mail would arrive at
+HostA,
+which would then do final delivery
+to user
+.q eric.
+.sh 2 "Mail to Files and Programs"
+.pp
+Files and programs are legitimate message recipients.
+Files provide archival storage of messages,
+useful for project administration and history.
+Programs are useful as recipients in a variety of situations,
+for example,
+to maintain a public repository of systems messages
+(such as the Berkeley
+.i msgs
+program).
+.pp
+Any address passing through the initial parsing algorithm
+as a local address
+(i.e, not appearing to be a valid address for another mailer)
+is scanned for two special cases.
+If prefixed by a vertical bar (\c
+.q \^|\^ )
+the rest of the address is processed as a shell command.
+If the user name begins with a slash mark (\c
+.q /\^ )
+the name is used as a file name,
+instead of a login name.
+.sh 2 "Aliasing, Forwarding, Inclusion"
+.pp
+.i Sendmail
+reroutes mail three ways.
+Aliasing applies system wide.
+Forwarding allows each user to reroute incoming mail
+destined for that account.
+Inclusion directs
+.i sendmail
+to read a file for a list of addresses,
+and is normally used
+in conjunction with aliasing.
+.sh 3 "Aliasing"
+.pp
+Aliasing maps local addresses to address lists using a system-wide file.
+This file is hashed to speed access.
+Only addresses that parse as local
+are allowed as aliases;
+this guarantees a unique key
+(since there are no nicknames for the local host).
+.sh 3 "Forwarding"
+.pp
+After aliasing,
+if an recipient address specifies a local user
+.i sendmail
+searches for a
+.q .forward
+file in the recipient's home directory.
+If it exists,
+the message is
+.i not
+sent to that user,
+but rather to the list of addresses in that file.
+Often
+this list will contain only one address,
+and the feature will be used for network mail forwarding.
+.pp
+Forwarding also permits a user to specify a private incoming mailer.
+For example,
+forwarding to:
+.(b
+"\^|\|/usr/local/newmail myname"
+.)b
+will use a different incoming mailer.
+.sh 3 "Inclusion"
+.pp
+Inclusion is specified in RFC 733 [Crocker77] syntax:
+.(b
+:Include: pathname
+.)b
+An address of this form reads the file specified by
+.i pathname
+and sends to all users listed in that file.
+.pp
+The intent is
+.i not
+to support direct use of this feature,
+but rather to use this as a subset of aliasing.
+For example,
+an alias of the form:
+.(b
+project: :include:/usr/project/userlist
+.)b
+is a method of letting a project maintain a mailing list
+without interaction with the system administration,
+even if the alias file is protected.
+.pp
+It is not necessary to rebuild the index on the alias database
+when a :include: list is changed.
+.sh 2 "Message Collection"
+.pp
+Once all recipient addresses are parsed and verified,
+the message is collected.
+The message comes in two parts:
+a message header and a message body,
+separated by a blank line.
+The body is an uninterpreted
+sequence of text lines.
+.pp
+The header is formated as a series of lines
+of the form
+.(b
+       field-name: field-value
+.)b
+Field-value can be split across lines by starting the following
+lines with a space or a tab.
+Some header fields have special internal meaning,
+and have appropriate special processing.
+Other headers are simply passed through.
+Some header fields may be added automatically,
+such as time stamps.
+.sh 1 "THE UUCP PROBLEM"
+.pp
+Of particular interest
+is the UUCP network.
+The explicit routing
+used in the UUCP environment
+causes a number of serious problems.
+First,
+giving out an address
+is impossible
+without knowing the address of your potential correspondent.
+This is typically handled
+by specifying the address
+relative to some
+.q "well-known"
+host
+(e.g.,
+ucbvax or decvax).
+Second,
+it is often difficult to compute
+the set of addresses
+to reply to
+without some knowledge
+of the topology of the network.
+Although it may be easy for a human being
+to do this
+under many circumstances,
+a program does not have equally sophisticated heuristics
+built in.
+Third,
+certain addresses will become painfully and unnecessarily long,
+as when a message is routed through many hosts in the USENET.
+And finally,
+certain
+.q "mixed domain"
+addresses
+are impossible to parse unambiguously \*-
+e.g.,
+.(l
+decvax!ucbvax!lbl-h!user@LBL-CSAM
+.)l
+might have many possible resolutions,
+depending on whether the message was first routed
+to decvax
+or to LBL-CSAM.
+.pp
+To solve this problem,
+the UUCP syntax
+would have to be changed to use addresses
+rather than routes.
+For example,
+the address
+.q decvax!ucbvax!eric
+might be expressed as
+.q eric@ucbvax.UUCP
+(with the hop through decvax implied).
+This address would itself be a domain-based address;
+for example,
+an address might be of the form:
+.(l
+mark@d.cbosg.btl.UUCP
+.)l
+Hosts outside of Bell Telephone Laboratories
+would then only need to know
+how to get to a designated BTL relay,
+and the BTL topology
+would only be maintained inside Bell.
+.pp
+There are three major problems
+associated with turning UUCP addresses
+into something reasonable:
+defining the namespace,
+creating and propagating the necessary software,
+and building and maintaining the database.
+.sh 2 "Defining the Namespace"
+.pp
+Putting all UUCP hosts into a flat namespace
+(e.g.,
+.q \&...@host.UUCP )
+is not practical for a number of reasons.
+First,
+with over 1600 sites already,
+and (with the increasing availability of inexpensive microcomputers
+and autodialers)
+several thousand more coming within a few years,
+the database update problem
+is simply intractable
+if the namespace is flat.
+Second,
+there are almost certainly name conflicts today.
+Third,
+as the number of sites grow
+the names become ever less mnemonic.
+.pp
+It seems inevitable
+that there be some sort of naming authority
+for the set of top level names
+in the UUCP domain,
+as unpleasant a possibility
+as that may seem.
+It will simply not be possible
+to have one host resolving all names.
+It may however be possible
+to handle this
+in a fashion similar to that of assigning names of newsgroups
+in USENET.
+However,
+it will be essential to encourage everyone
+to become subdomains of an existing domain
+whenever possible \*-
+even though this will certainly bruise some egos.
+For example,
+if a new host named
+.q blid
+were to be added to the UUCP network,
+it would probably actually be addressed as
+.q d.bli.UUCP
+(i.e.,
+as host
+.q d
+in the pseudo-domain
+.q bli
+rather than as host
+.q blid
+in the UUCP domain).
+.sh 2 "Creating and Propagating the Software"
+.pp
+The software required to implement a consistent namespace
+is relatively trivial.
+Two modules are needed,
+one to handle incoming mail
+and one to handle outgoing mail.
+.pp
+The incoming module
+must be prepared to handle either old or new style addresses.
+New-style addresses
+can be passed through unchanged.
+Old style addresses
+must be turned into new style addresses
+where possible.
+.pp
+The outgoing module
+is slightly trickier.
+It must do a database lookup on the recipient addresses
+(passed on the command line)
+to determine what hosts to send the message to.
+If those hosts do not accept new-style addresses,
+it must transform all addresses in the header of the message
+into old style using the database lookup.
+.pp
+Both of these modules
+are straightforward
+except for the issue of modifying the header.
+It seems prudent to choose one format
+for the message headers.
+For a number of reasons,
+Berkeley has elected to use the ARPANET protocols
+for message formats.
+However,
+this protocol is somewhat difficult to parse.
+.pp
+Propagation is somewhat more difficult.
+There are a large number of hosts
+connected to UUCP
+that will want to run completely standard systems
+(for very good reasons).
+The strategy is not to convert the entire network \*-
+only enough of it it alleviate the problem.
+.sh 2 "Building and Maintaining the Database"
+.pp
+This is by far the most difficult problem.
+A prototype for this database
+already exists,
+but it is maintained by hand
+and does not pretend to be complete.
+.pp
+This problem will be reduced considerably
+if people choose to group their hosts
+into subdomains.
+This would require a global update
+only when a new top level domain
+joined the network.
+A message to a host in a subdomain
+could simply be routed to a known domain gateway
+for further processing.
+For example,
+the address
+.q eric@a.bli.UUCP
+might be routed to the
+.q bli
+gateway
+for redistribution;
+new hosts could be added
+within BLI
+without notifying the rest of the world.
+Of course,
+other hosts
+.i could
+be notified as an efficiency measure.
+.pp
+There may be more than one domain gateway.
+A domain such as BTL,
+for instance,
+might have a dozen gateways to the outside world;
+a non-BTL site
+could choose the closest gateway.
+The only restriction
+would be that all gateways
+maintain a consistent view of the domain
+they represent.
+.sh 2 "Logical Structure"
+.pp
+Logically,
+domains are organized into a tree.
+There need not be a host actually associated
+with each level in the tree \*-
+for example,
+there will be no host associated with the name
+.q UUCP.
+Similarly,
+an organization might group names together for administrative reasons;
+for example,
+the name
+.(l
+CAD.research.BigCorp.UUCP
+.)l
+might not actually have a host representing
+.q research.
+.pp
+However,
+it may frequently be convenient to have a host
+or hosts
+that
+.q represent
+a domain.
+For example,
+if a single host exists that
+represents
+Berkeley,
+then mail from outside Berkeley
+can forward mail to that host
+for further resolution
+without knowing Berkeley's
+(rather volatile)
+topology.
+This is not unlike the operation
+of the telephone network.
+.pp
+This may also be useful
+inside certain large domains.
+For example,
+at Berkeley it may be presumed
+that most hosts know about other hosts
+inside the Berkeley domain.
+But if they process an address
+that is unknown,
+they can pass it
+.q upstairs
+for further examination.
+Thus as new hosts are added
+only one host
+(the domain master)
+.i must
+be updated immediately;
+other hosts can be updated as convenient.
+.pp
+Ideally this name resolution process
+would be performed by a name server
+(e.g., [Su82b])
+to avoid unnecessary copying
+of the message.
+However,
+in a batch network
+such as UUCP
+this could result in unnecessary delays.
+.sh 1 "COMPARISON WITH DELIVERMAIL"
+.pp
+.i Sendmail
+is an outgrowth of
+.i delivermail .
+The primary differences are:
+.np
+Configuration information is not compiled in.
+This change simplifies many of the problems
+of moving to other machines.
+It also allows easy debugging of new mailers.
+.np
+Address parsing is more flexible.
+For example,
+.i delivermail
+only supported one gateway to any network,
+whereas
+.i sendmail
+can be sensitive to host names
+and reroute to different gateways.
+.np
+Forwarding and
+:include:
+features eliminate the requirement that the system alias file
+be writable by any user
+(or that an update program be written,
+or that the system administration make all changes).
+.np
+.i Sendmail
+supports message batching across networks
+when a message is being sent to multiple recipients.
+.np
+A mail queue is provided in
+.i sendmail.
+Mail that cannot be delivered immediately
+but can potentially be delivered later
+is stored in this queue for a later retry.
+The queue also provides a buffer against system crashes;
+after the message has been collected
+it may be reliably redelivered
+even if the system crashes during the initial delivery.
+.np
+.i Sendmail
+uses the networking support provided by 4.2BSD
+to provide a direct interface networks such as the ARPANET
+and/or Ethernet
+using SMTP (the Simple Mail Transfer Protocol)
+over a TCP/IP connection.

+.Sh NAME
+.Nm makemap
+.Nd create database maps for sendmail
+.Sh SYNOPSIS
+.Nm
+.Op Fl N
+.Op Fl f
+.Op Fl o
+.Op Fl r
+.Op Fl v
+.Ar maptype
+.Ar mapname
+.Sh DESCRIPTION
+.Nm
+creates the database maps used by the keyed map lookups in
+.Xr sendmail 8 .
+It reads input from the standard input
+and outputs them to the indicated
+.Ar mapname .
+.Pp
+Depending on how it is compiled,
+.Nm
+handles up to three different database formats,
+selected using the
+.Ar maptype
+parameter.
+They may be
+.Bl -tag -width Fl
+.It Li dbm
+DBM format maps.
+This requires the
+.Xr ndbm 3
+library.
+.It Li btree
+B-Tree format maps.
+This requires the new Berkeley
+.Xr db 3
+library.
+.It Li hash
+Hash format maps.
+This also requires the
+.Xr db 3
+library.
+.El
+.Pp
+In all cases,
+.Nm
+reads lines from the standard input consisting of two
+words separated by white space.
+The first is the database key,
+the second is the value.
+The value may contain
+``%\fIn\fP''
+strings to indicated parameter substitution.
+Literal parentheses should be doubled
+(``%%'').
+Blank lines and lines beginning with ``#'' are ignored.
+.Ss Flags
+.Bl -tag -width Fl
+.It Fl N
+Include the null byte that terminates strings
+in the map.
+This must match the \-N flag in the sendmail.cf
+``K'' line.
+.It Fl f
+Fold all upper case letters in the key
+to lower case;
+this is intended to mesh with the
+\-f flag in the
+\fBK\fP
+line in sendmail.cf.
+The value is not case folded.
+.It Fl o
+Append to an old file.
+This allows you to augment an existing file.
+.It Fl r
+Allow replacement of existing keys.
+Normally
+.Nm
+complains if you repeat a key,
+and does not do the insert.
+.It Fl v
+Verbosely print what it is doing.
+.El
+.Sh SEE ALSO
+.Xr sendmail 8
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Bx 4.4 .

+
+The Makefile is for the new Berkeley make, available from ftp.uu.net
+in the directory /systems/unix/bsd-sources/usr.bin/make.  There is
+also a Makefile.dist which is much less clever, but works on the old
+traditional make.  You can use this using:
+
+       make -f Makefile.dist
+
+There are a couple of other Makefiles for other systems -- these are
+the ones that I use, they have "Berkeley quirks" in them, and I don't
+guarantee that they will work in your environment.  To make it worse,
+some are for the new Berkeley make, and some are for the old make.
+I provide them for information only.  Still, they may help you get
+started.  They have names like "Makefile.HPUX".
+
+Whereever possible, I try to make sendmail pull in the correct
+compilation options needed to compile on various environments based on
+automatically defined symbols.  Some machines don't seem to have useful
+symbols availble, requiring the following compilation flags in the
+Makefile:
+
+SOLARIS                Define this if you are running Solaris 2.0 or higher.
+NeXT           Define this if you are on a NeXT box.
+_AIX3          Define this if you are IBM AIX 3.x.
+
+If you are a system that sendmail has already been ported to, you
+probably won't have to touch these.  But if you are porting, you may
+have to tweak the following compilation flags in order to get
+it to compile and link properly:
+
+UNSETENV       Define this if your system library does NOT include the
+               "unsetenv" subroutine.
+SYSTEM5                Adjust for System V.
+LOCKF          Set this if you do not have the flock system call -- it
+               will revert to System V file locking.  There are some
+               semantic gotchas, so flock is preferred.  Implied by
+               SYSTEM5.
+SYS5TZ         Use System V-style time zones.  If not set, the TZ
+               environment variable is ignored.  Implied by SYSTEM5.
+HASUNAME       Set if you have the "uname" system call.  Implied by
+               SYSTEM5.
+HASSTATFS      Define this if you have the statfs(2) system call.  It's
+               not a disaster to get this wrong -- but you do lose the
+               queue free space code.
+HASUSTAT       Define this if you have the ustat(2) system call.  It's
+               not a disaster to get this wrong -- but you do lose the
+               queue free space code.
+HASSETSID      Define this if you have the setsid(2) system call.  This
+               is implied if your system appears to be POSIX compliant.
+HASINITGROUPS  Define this if you have the initgroups(3) routine.
+LA_TYPE                The type of load average your kernel supports.  These
+               can be LA_SUBR (4) if you have the getloadavg(3) routine,
+               LA_FLOAT (3) if you read kmem and interpret the value
+               as a floating point number, LA_INT (2) to interpret as
+               an integer.  These last two have several other parameters
+               that they try to divine: the name of your kernel, the name
+               of the variable in the kernel to examine, the number of
+               bits of precision in a fixed point load average, and so
+               forth.  In desparation, use LA_ZERO -- it always returns
+               the load average as "zero" (and does so on all architectures).
+               The actual code is in conf.c -- it can be tweaked if you
+               are brave.
+
+There are a bunch of features that you can decide to compile in, such
+as selecting various database packages and special protocol support.
+Several are assumed based on other compilation flags -- if you want to
+"un-assume" something, you probably need to edit conf.h.  Compilation
+flags that add support for special features include:
+
+NDBM           Include support for "new" DBM library for aliases and maps.
+NEWDB          Include support for Berkeley "db" package (hash & btree)
+               for aliases and maps.
+NIS            Define this to get NIS (YP) support for aliases and maps.
+YPCOMPAT       Define this to force building of DBM versions of alias
+               files even if you have NEWDB defined; this will only
+               occur on NIS master machines.  It is independent of NIS.
+USERDB         Include support for the User Information Database.  Implied
+               by NEWDB conf.h.
+IDENTPROTO     Define this to get IDENT (RFC 1413) protocol support.
+               This is assumed unless you are running on Ultrix or
+               HP-UX, both of which have a problem in the UDP
+               implementation.
+MIME           Include support for MIME-encapsulated error messages.
+FROZENCONFIG   Define this to get support for frozen configuration
+               files.  Frozen configurations make sense if your I/O system
+               is fast relative to your processor.  At this point this
+               is NOT recommended.
+LOG            Set this to get syslog(3) support.  Defined by default
+               in conf.h.  You want this if at all possible.
+NETINET                Set this to get TCP/IP support.  Defined by default
+               in conf.h.  You probably want this.
+NETISO         Define this to get ISO networking support.
+SMTP           Define this to get the SMTP code.  Implied by NETINET
+               or NETISO.
+NAMED_BIND     Define this to get DNS (name daemon) support, including
+               MX support.  The specs you must use this if you run
+               SMTP.  Defined by default in conf.h.
+QUEUE          Define this to get queueing code.  Implied by NETINET
+               or NETISO; required by SMTP.  This gives you other good
+               stuff -- it should be on.
+DAEMON         Define this to get general network support.  Implied by
+               NETINET or NETISO.  Defined by default in conf.h.  You
+               almost certainly want it on.
+MATCHGECOS     Permit fuzzy matching of user names against the full
+               name (GECOS) field in the /etc/passwd file.  This should
+               probably be on, since you can disable it from the config
+               file if you want to.  Defined by default in conf.h.
+SETPROCTITLE   Try to set the string printed by "ps" to something
+               informative about what sendmail is doing.  Defined by
+               default in conf.h.
+
+If you are compiling on SunOS and want to use frozen configuration
+files, you must use -Bstatic -- if you do not, frozen configuration
+files fail in bizarre ways and you will open up several security holes.
+
+If you are compiling on OSF/1 (DEC Alpha), you must use -lmld.
+
+If you use both -DNDBM and -DNEWDB, you must delete the module ndbm.o
+from libdb.a and delete the file "ndbm.h" from the files that get
+installed (that is, use the OLD ndbm.h, not the new ndbm.h).  This
+compatibility module maps ndbm calls into DB calls, and breaks things
+rather badly.
+
+You probably want to look over the compilation options in conf.h
+before you compile.  These are intended to be per-site information.

-**     The process is kind of strange.  There are a number of

-**             1.  comment <address> comment   ==> comment <$g> comment
-**             2.  address                     ==> address

-**             4.  (comment) address           ==> (comment) $g
-**     And then there are the hard cases....
-**             5.  add (comment) ress          ==> $g (comment)
-**             6.  comment <address (comment)> ==> comment <$g (comment)>
-**             7.    .... etc ....
+**     This algorithm has been cleaned up to handle a wider range

+**             if they were ok, FALSE otherwise.  Fill in map with the
+**             values.
+**
+**     char *map_lookup(MAP *map, char *key, char **args, int *pstat)
+**             Look up the key in the given map.  If found, do any
+**             rewriting the map wants (including "args" if desired)
+**             and return the value.  Set *pstat to the appropriate status
+**             on error and return NULL.  Args will be NULL if called
+**             from the alias routines, although this should probably
+**             not be relied upon.  It is suggested you call map_rewrite
+**             to return the results -- it takes care of null termination
+**             and uses a dynamically expanded buffer as needed.
+**
+**     void map_store(MAP *map, char *key, char *value)
+**             Store the key:value pair in the map.
+**
+**     bool map_open(MAP *map, int mode)
+**             Open the map for the indicated mode.  Mode should
+**             be either O_RDONLY or O_RDWR.  Return TRUE if it
+**             was opened successfully, FALSE otherwise.  If the open
+**             failed an the MF_OPTIONAL flag is not set, it should
+**             also print an error.  If the MF_ALIAS bit is set
+**             and this map class understands the @:@ convention, it
+**             should call aliaswait() before returning.
+**

+**
+**     MaxMciCache is the maximum number of open connections that

+**
+**     MciCacheTimeout is the time (in seconds) that a connection
+**     is permitted to survive without activity.
+**
+**     We actually try any cached connections by sending a NOOP
+**     before we use them; if the NOOP fails we close down the
+**     connection and reopen it.  Note that this means that a
+**     server SMTP that doesn't support NOOP will hose the

+ *  SYSEXITS.H -- Exit status codes for system programs.
+ *
+ *     This include file attempts to categorize possible error
+ *     exit statuses for system programs, notably delivermail
+ *     and the Berkeley network.
+ *
+ *     Error numbers begin at EX__BASE to reduce the possibility of
+ *     clashing with other exit statuses that random programs may
+ *     already return.  The meaning of the codes is approximately
+ *     as follows:
+ *
+ *     EX_USAGE -- The command was used incorrectly, e.g., with
+ *             the wrong number of arguments, a bad flag, a bad
+ *             syntax in a parameter, or whatever.
+ *     EX_DATAERR -- The input data was incorrect in some way.
+ *             This should only be used for user's data & not
+ *             system files.
+ *     EX_NOINPUT -- An input file (not a system file) did not
+ *             exist or was not readable.  This could also include
+ *             errors like "No message" to a mailer (if it cared
+ *             to catch it).
+ *     EX_NOUSER -- The user specified did not exist.  This might
+ *             be used for mail addresses or remote logins.
+ *     EX_NOHOST -- The host specified did not exist.  This is used
+ *             in mail addresses or network requests.
+ *     EX_UNAVAILABLE -- A service is unavailable.  This can occur
+ *             if a support program or file does not exist.  This
+ *             can also be used as a catchall message when something
+ *             you wanted to do doesn't work, but you don't know
+ *             why.
+ *     EX_SOFTWARE -- An internal software error has been detected.
+ *             This should be limited to non-operating system related
+ *             errors as possible.
+ *     EX_OSERR -- An operating system error has been detected.
+ *             This is intended to be used for such things as "cannot
+ *             fork", "cannot create pipe", or the like.  It includes
+ *             things like getuid returning a user that does not
+ *             exist in the passwd file.
+ *     EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp,
+ *             etc.) does not exist, cannot be opened, or has some
+ *             sort of error (e.g., syntax error).
+ *     EX_CANTCREAT -- A (user specified) output file cannot be
+ *             created.
+ *     EX_IOERR -- An error occurred while doing I/O on some file.
+ *     EX_TEMPFAIL -- temporary failure, indicating something that
+ *             is not really an error.  In sendmail, this means
+ *             that a mailer (e.g.) could not create a connection,
+ *             and the request should be reattempted later.
+ *     EX_PROTOCOL -- the remote system returned something that
+ *             was "not possible" during a protocol exchange.
+ *     EX_NOPERM -- You did not have sufficient permission to
+ *             perform the operation.  This is not intended for
+ *             file system problems, which should use NOINPUT or
+ *             CANTCREAT, but rather for higher level permissions.
