+8.6.3/8.6.3 93/10/24
+ IMPORTANT FIX: Fix several problems that caused open files to
+ be "lost" during queue runs; this overflowed the open
+ file table on large runs. An assumption that fdopen
+ always succeeds sometimes resulted in core dumps when
+ this happens; sometimes the message is delivered twice,
+ sometimes (probably) infinite times. This problem in
+ various form was reported by P{r (Pell) Emanuelsson and
+ Robert Campbell of U.C. Berkeley.
+ Special diagnosis of EMFILE error conditions -- it now prints
+ the known open file descriptors so you can figure out
+ what is consuming so much resources.
+ Fix a couple of problems caused by early address parsing
+ errors -- one caused it to return a "this is only a
+ warning" when it really wasn't, and the other started
+ parsing through a random pointer. The first was
+ noted by Eric Wassenaar.
+ Fix an infinite loop problem caused by null components in the
+ host signature. Problem noted by Jan Sorensen.
+ Be sure to reset the "current date" when sending an error
+ message -- PostMasterCopy messages were being sent
+ with an old Date: header.
+ Fix a problem that caused duplicated mail when sendmail was
+ (1) compiled without HASFLOCK, (2) you are sending to
+ an alias that has an owner-* alias, (3) you execute
+ sendmail with -t flag, (4) you run in -odb mode, and
+ (5) the sender specifies both the alias name and
+ another alias [i.e., the envelope is split], then
+ duplicate messages are sent. The problem description
+ and one-line fix are from Motonori Nakamura of Kyoto
+ University.
+ Avoid a problem that causes error messages to be discarded
+ in some cases -- this was the result of a "fix" to
+ avoid duplicate error messages, but two are better
+ than zero. Reported by Tim Rylance.
+ Fix a minor botch in checkfd012() -- fix from Dave Hill of
+ Computervision R&D Ltd.
+ Remove "X-Authentication-Warning: <user> set sender to <address>
+ using -f" entirely -- it is far too eager to include
+ this, and it is confusing folks. I'll try to make it
+ work "right" in 8.7. Problem noted by Yoshitaka
+ Tokugawa of dit Co., Ltd.
+ Fix a race condition with the errno value in tick() and
+ reapchild() -- this caused occasional misdiagnosis
+ of problems. Kyle Jones of UUNET helped this along.
+ Repair rule loop-detection code. From Michael Corrigan of
+ U.C. San Diego.
+ Fix a problem that caused sender domain addition (C mailer
+ flag to be ignored if you use -odq or use -odb with
+ a high load average. Problem reported by Jim Murray
+ of Stratus.
+ Fix ident protocol on multi-homed machines. It was not
+ always using the correct interface. Fix from J.R.
+ Oldroyd of Opal.
+ Previously, sendmail assumed that any SMTP greeting message
+ that wasn't 2xx was a temporary failure -- it should
+ only take 4xx as a temporary failure, and return a
+ solid error message on anything else -- for example,
+ to allow you to reject connections on a workstation
+ that is MXed to a mail server.
+ Portability enhancements for 386BSD/FreeBSD/NetBSD from
+ Ollivier Robert.
+ CONFIG: FEATURE(always_add_domain) didn't always add the domain;
+ in particular, on local mail it modified the header sender
+ but not the header recipient address(es). Reported by
+ Jeffrey Honig of Cornell University. Also, strip
+ any host from envelope recipient address(es), since
+ local mailers don't understand host names -- this is
+ to help mailertable entries. From Christopher Davis.
+ CONFIG: masquerading didn't apply to addresses that already
+ had a domain. This change replaces a local hostname
+ by the masquerade name in the SMTP mailer (previously
+ it only added the masquerade name if it didn't already
+ have a domain name). Several people complained about
+ this.
+
+8.6.2/8.6.2 93/10/15
+ Put a "successful delivery" message in the transcript for
+ addresses that get return-receipts.
+ Put a prominent "this is only a warning" message in warning
+ messages -- some people don't read carefully enough
+ and end up sending the message several times.
+ Include reason for temporary failure in the "warning" return
+ message. Currently, it just says "cannot send for
+ four hours".
+ Fix the "Original message received" time generated for
+ returntosender messages. It was previously listed as
+ the current time. Bug reported by Eric Hagberg of
+ Cornell University Medical College.
+ If there is an error when writing the body of a message,
+ don't send the trailing dot and wait for a response
+ in sender SMTP, as this could cause the connection to
+ hang up under some bizarre circumstances. From Eric
+ Wassenaar.
+ Fix some server SMTP synchronization problems caused when
+ connections fail during message collection. From
+ Eric Wassenaar.
+ Fix a problem that can cause srvrsmtp to reject mail if the
+ name server is down -- it accepts the RCPT but rejects
+ the DATA command. Problem reported by Jim Murray of
+ Stratus.
+ Fix a problem that can cause core dumps if the config file
+ incorrectly resolves to a null hostname. Reported by
+ Allan Johannesen of WPI.
+ Non-root use of -C flag, dangerous -f flags, and use of -oQ
+ by non-root users were not put into
+ X-Authentication-Warning:s as intended because the
+ config file hadn't set the PrivacyFlags yet. Fix
+ from Sven-Ove Westberg of the University of Lulea.
+ Under very odd circumstances, the alias file rebuild code
+ could get confused as to whether a database was
+ open or not.
+ Check "vendor code" on the end of V lines -- this is
+ intended to provide a hook for vendor-specific
+ configuration syntax. (This is a "new feature",
+ but I've made an exception to my rule in a belief
+ that this is a highly exceptional case.)
+ Portability fixes for DG/UX (from Douglas Anderson of NCSC),
+ SCO Unix (from Murray Kucherawy), A/UX, and OSF/1
+ (from Jon Forrest of UC Berkeley)
+ CONFIG: fix ``mailer:host'' form of UUCP relay naming.
+
+8.6.1/8.6 93/10/08
+ Portability fixes for A/UX and Encore UMAX V.
+ Fix error message handling -- if you had a name server down
+ causing an error during parsing, that message was never
+ propogated to the queue file.
+
+8.6/8.6 93/10/05
+ Configuration cleanup: make it easier to undo IDENTPROTO in
+ conf.h (other systems have the same bug).
+ If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume
+ getdtablesize() instead of sysconf(); a disturbingly
+ large number of systems defined _SC_OPEN_MAX in the
+ header files but don't have the syscall.
+ Another patch to really truly ignore MX records in getcanonname
+ if trymx == FALSE.
+ Fix problem that caused the "250 IAA25499 Message accepted for
+ delivery" message to be omitted if there was an error
+ in the header of the message (e.g., a bad Errors-To:
+ line). Pointed out by Michael Corrigan of UCSD.
+ Announce name of host we are chatting when we get errors; this
+ is an IDA-ism suggested by Christophe Wolfhugel.
+ Portability fixes for Alpha OSF/1 (from Anthony Baxter of the
+ Australian Artificial Intelligence Institute), SCO Unix
+ (from Murray Kucherawy of Hookup Communication Corp.),
+ NeXT (from Vince DeMarco and myself), Linux (from
+ Karl London <karl@borg.demon.co.uk>), BSDI (from
+ Christophe Wolfhugel, and SVR4 on Dell (from Kimmo
+ Suominen), AUX 3.0 on Macintosh, and ANSI C compilers.
+ Some changes to get around gcc optimizer bugs. From Takahiro
+ Kanbe.
+ Fix error recovery in queueup if another tf file of the same
+ name already exists. Problem stumbled over by Bill
+ Wisner of The Well.
+ Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes.
+ Problem noted by Keith McMillan of Ameritech Services.
+ Deal with group permissions properly when opening .forward and
+ :include: files. This relaxes the 8.1C restrictions
+ slightly more. This includes proper setting of groups
+ when reading :include: files, allowing you to read some
+ files that you should be able to read but have previously
+ been denied unless you owned them or they had "other"
+ read permission.
+ Make certain that $j is in $=w (after the .cf is read) so that
+ if the user is forced to override some silly system,
+ MX suppression will still work.
+ Fix a couple of efficiency problems where newstr was double-
+ calling expensive routines. In at least one case, it
+ wasn't guaranteed that they would always return the
+ same result. Problem noted by Christophe Wolfhugel.
+ Fix null pointer dereference in putoutmsg -- only on an error
+ condition from a non-SMTP mailer. From Motonori
+ Nakamura.
+ Macro expand "C" line class definitions before scanning so that
+ "CX $Z" works.
+ Fix problem that caused error message to be sent while still
+ trying to send the original message if the connection
+ is closed during a DATA command after getting an error
+ on an RCPT command (pretty obscure). Problem reported
+ by John Myers of CMU.
+ Fix reply to NOOP to be 250 instead of 200 -- this is a long
+ term bug.
+ Fix a nasty bug causing core dumps when returning the "warning:
+ cannot deliver for N hours -- will keep trying" message;
+ it only occurred if you had PostMasterCopy set and
+ only on some architectures. Although sendmail would
+ keep trying, it would send error messages on each
+ queue interval. This is an important fix.
+ Allow u and g options to take user and group names respectively.
+ Don't do a chdir into the queue directory in -bt mode to make
+ ruleset testing a bit easier.
+ Don't allow users to turn off logging (using -oL) on the command
+ line -- command line can only raise, not lower, logging
+ level.
+ Set $u to the original recipient on the SMTP transaction or on
+ the command line. This is only done if there is exactly
+ one recipient. Technically, this does not meet the
+ specs, because it does not guarantee a domain on the
+ address.
+ Fix a problem that dumped error messages on bad addresses if
+ you used the -t flag. Problem noted by Josh Smith of
+ Harvey Mudd College.
+ Given an address such as ``<foo> <bar>'', auto-quote the first
+ ``<foo>'' part, giving ``"<foo>" <bar>''. This is to
+ avoid the problem of people who use angle brackets in
+ their full name information.
+ Fix a null pointer dereference if you set option "l", have
+ an Errors-To: header in the message, and have Errors-To:
+ defined in the config file H lines. From J.R. Oldroyd.
+ Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get
+ wrong when compiling. Suggested by Rick McCarty of TI.
+ Fix a problem that could pass negative SIZE parameter if the
+ df file got lost; this would cause servers to always
+ give a temporary failure, making the problem even worse.
+ Problem noted by Allan Johannesen of WPI.
+ Add "ident" timeout (one of the "r" option selectors) for IDENT
+ protocol timeouts (30s default). Requested by Murray
+ Kucherawy of HookUp Communication Corp. to handle bogus
+ PC TCP/IP implementations.
+ Change $w default definition to be just the first component of
+ the domain name on config level 5. The $j macro defaults
+ to the FQDN; $m remains as before. This lets well-behaved
+ config files use any of the short, long, or subdomain
+ names.
+ Add makesendmail script in src to try to automate multi-architecture
+ builds. I know, this is sub-optimal, but it is still
+ helpful.
+ Fix very obscure race condition that can cause a queue run to
+ get a queue file for an already completed job. This
+ problem has existed for years. Problem noted by the
+ long suffering Allan Johannesen of WPI.
+ Fix a problem that caused the raw sender name to be passed to
+ udbsender instead of the canonified name -- this caused
+ it to sometimes miss records that it should have found.
+ Relax check of name on HELO packet so that a program using -bs
+ that claims to be itself works properly.
+ Restore rewriting of $: part of address through 2, R, 4 in
+ buildaddr -- this requires passing a lot of flags to get
+ it right. Unlike old versions, this ONLY rewrites
+ recipient addresses, not sender addresses.
+ Fix a bug that caused core dumps in config files that cannot
+ resolve /file/name style addresses. Fix from Jonathan
+ Kamens of OpenVision Technologies.
+ Fix problem with fcntl locking that can cause error returns to
+ be lost if the lock is lost; this required fully
+ queueing everything, dropping the envelope (so errors
+ would get returned), and then re-reading the queue from
+ scratch.
+ Fix a problem that caused aliases that redefine an otherwise
+ true address to still send to the original address
+ if and only if the alias failed in certain bizarre
+ ways (e.g, if they pointed at a list:; syntax address).
+ Problem pointed out by Jonathan Kamens.
+ Remove support for frozen configuration files. They caused
+ more trouble than it was worth.
+ Fix problem that can cause error messages to get ignored when
+ using both -odb and -t flags. Problem noted by Rob
+ McNicholas at U.C. Berkeley.
+ Include all "normal" variations on hostname in $=w. For example,
+ if the host name is vangogh.cs.berkeley.edu, $=w will
+ contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu.
+ Add "restrictqrun" privacy flag -- without this, anyone can run
+ the queue.
+ Reset SmtpPhase global on initial connection creation so that
+ messages don't come out with stale information.
+ Pass an "ext" argument to lockfile so that error/log messages
+ will properly reflect the true filename being locked.
+ Put all [...] address forms into $=w -- this eliminates the need
+ for MAXIPADDR in conf.h. Suggested by John Gardiner
+ Myers of CMU.
+ Fix a bug that can cause qf files to be left around even after
+ an SMTP RSET command. Problem and fix from Michael
+ Corrigan.
+ Don't send a PostMasterCopy to errors when the Precedence: is
+ negative. Error reports still go to the envelope
+ sender address.
+ Add LA_SHORT for load averages.
+ Lock sendmail.st file when posting statistics.
+ Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to
+ set the size of the TCP send and receive buffers; if you
+ run over a slow slip line you may need to set these down
+ (although it would be better to fix the SLIP implementation
+ so that it's not necessary to recompile every program
+ that does bulk data transfer).
+ Allow null defaults on $( ... $) lookups. Problem reported by
+ Amir Plivatsky.
+ Diagnose crufty S and V config lines. This resulted from an
+ observation that some people were using the SITE macro
+ without the SITECONFIG macro first, which was causing
+ bogus config files that were not caught.
+ Fix makemap -f flag to turn off case folding (it was turning it
+ on instead). THIS IS A USER VISIBLE CHANGE!!!
+ Fix a problem that caused multiple error messages to be sent if
+ you used "sendmail -t -oem -odb", your system uses fcntl
+ locking, and one of the recipient addresses is unknown.
+ Reset uid earlier in include() so that recursive .forwards or
+ :include:s don't use the wrong uid.
+ If file descriptor 0, 1, or 2 was closed when sendmail was
+ called, the code to recover the descriptor was broken.
+ This sometimes (only sometimes) caused problems with the
+ alias file. Fix from Motonori Nakamura.
+ Fix a problem that caused aliaswait to go into infinite recursion
+ if the @:@ metasymbol wasn't found in the alias file.
+ Improve error message on newaliases if database files cannot be
+ opened or if running with no database format defined.
+ Do a better estimation of the size of error messages when NoReturn
+ is set. Problem noted by P{r (Pell) Emanuelsson.
+ Fix a problem causing the "c" option (don't connect to expensive
+ mailers) to be ignored in SMTP. Problem noted and the
+ solution suggested by Robert Elz of Munnari University.
+ Improve connection caching algorithm by passing "[host]" to
+ hostsignature, which strips the square brackets and
+ returns the real name. This allows mailertable entries
+ to match regular entries.
+ Re-enable Return-Receipt-To: -- people seem to want this stupid
+ feature, even if it doesn't work right.
+ Catch and log attempts to try the "wiz" command in server SMTP.
+ This also ups the log level from LOG_NOTICE to LOG_CRIT.
+ Be more generous at assigning $z to the home directory -- do this
+ for programs that are specified through a .forward file.
+ Fix from Andrew Chang of Sun Microsystems.
+ Always save a fatal error message in preference to a non-fatal
+ error message so that the "subject" line of return
+ messages is the best possible.
+ CONFIG: reduce the number of quotes needed to quote configuration
+ parameters with commas: two quotes should work now, e.g.,
+ define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local'').
+ CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom
+ connections (domain-ized UUCP).
+ CONFIG: fix bug in default maps (-o must be before database file
+ name). Pointed out by Christophe Wolfhugel.
+ CONFIG: add FEATURE(nodns) to state that we are not relying on
+ DNS. This would presumably be used in UUCP islands.
+ CONFIG: add OSTYPE(nextstep) and OSTYPE(linux).
+ CONFIG: log $u in Received: line. This is in technical violation
+ of the standards, since it doesn't guarantee a domain
+ on the address.
+ CONFIG: don't assume "m" in local mailer flags -- this means that
+ if you redefine LOCAL_MAILER_FLAGS you will have to include
+ the "m" flag should you want it. Apparently some Solaris 2.2
+ installations can't handle multiple local recipients.
+ Problem noted by Josh Smith.
+ CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults).
+ CONFIG: change default version level from 4 to 5.
+ CONFIG: add FEATURE(nullclient) to create a config file that
+ forwards all mail to a hub without ever looking at the
+ addresses in any detail.
+ CONFIG: properly strip mailer: information off of relays when
+ used to change .BITNET form into %-hack form.
+ CONFIG: fix a problem that caused infinite loops if presented
+ with an address such as "!foo".
+ CONFIG: check for self literal (e.g., [128.32.131.12]) even if
+ the reverse "PTR" mapping is broken. There's a better
+ way to do this, but the change is fairly major and I
+ want to hold it for another release. Problem noted by
+ Bret Marquis.
+
+8.5/8.5 93/07/23
+ Serious bug: if you used a command line recipient that was unknown
+ sendmail would not send a return message (it was treating
+ everything as though it had an SMTP-style client that
+ would do the return itself). Problem noted by Josh Smith.
+ Change "trymx" option in getcanonname() to ignore all MX data,
+ even during a T_ANY query. This actually didn't break
+ anything, because the only time you called getcanonname
+ with !trymx was if you already knew there were no MX
+ records, but it is somewhat cleaner. From Motonori
+ Nakamura.
+ Don't call getcanonname from getmxrr if you already know there
+ are no DNS records matching the name.
+ Fix a problem causing error messages to always include "The
+ original message was received ... from localhost".
+ The correct original host information is now included.
+ Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their
+ version of "test" doesn't have the -x flag). Change it
+ to use -f instead. From John Myers.
+ CONFIG: 8.4 mistakenly set the default SMTP-style mailer to
+ esmtp -- it should be smtp.
+ CONFIG: send all relayed mail using confRELAY_MAILER (defaults
+ to "relay" (a variant of "smtp") if MAILER(smtp) is used,
+ else "suucp" if MAILER(uucp) is used, else "unknown");
+ this cleans up the configs somewhat. This fixes a serious
+ problem that caused route-addrs to get mistaken as relays,
+ pointed out by John Myers. WARNING: this also causes
+ the default on SMART_HOST to change from "suucp" to
+ "relay" if you have MAILER(smtp) specified.
+
+8.4/8.4 93/07/22
+ Add option `w'. If you receive a message that comes to you because
+ you are the best (lowest preference) target of an MX, and
+ you haven't explicitly recognized the source MX host in
+ your .cf file, this option will cause you to try the target
+ host directly (as if there were no MX for it at all). If
+ `w' is not set, this case is a configuration error.
+ Beware: if `w' is set, senders may get bogus errors like
+ "message timed out" or "host unknown" for problems that
+ are really configuration errors. This option is
+ disrecommended, provided only for compatibility with
+ UIUC sendmail.
+ Fix a problem that caused the incoming socket to be left open
+ when sendmail forks after the DATA command. This caused
+ calling systems to wait in FIN_WAIT_2 state until the
+ entire list was processed and the child closed -- a
+ potentially prodigious amount of time. Problem noted
+ by Neil Rickert.
+ Fix problem (created in 6.64) that caused mail sent to multiple
+ addresses, one of which was a bad address, to completely
+ suppress the sending of the message. This changes
+ handling of EF_FATALERRS somewhat, and adds an
+ EF_GLOBALERRS flag. This also fixes a potential problem
+ with duplicate error messages if there is a syntax error
+ in the header of a message that isn't noticed until late
+ in processing. Original problem pointed out by Josh Smith
+ of Harvey Mudd College. This release includes quite a bit
+ of dickering with error handling (see below).
+ Back out SMTP transaction if MAIL gets nested 501 error. This
+ will only hurt already-broken software and should help
+ humans.
+ Fix a problem that broke aliases when neither NDBM nor NEWDB were
+ compiled in. It would never read the alias file.
+ Repair unbalanced `)' and `>' (the "open" versions are already
+ repaired).
+ Logging of "done" in dropenvelope() was incorrect: it would
+ log this even when the queue file still existed. Change
+ this to only log "done" (at log level 11) when the
+ queue file is actually removed. From John Myers.
+ Log "lost connection" in server SMTP at log level 20 if there
+ is no pending transaction. Some senders just close the
+ connection rather than sending QUIT.
+ Fix a bug causing getmxrr to add a dot to the end of unqualified
+ domains that do not have MX records -- this would cause
+ the subsequent host name lookup to fail. The problem
+ only occurred if you had FEATURE(nocanonify) set.
+ Problem noted by Rick McCarty of Texas Instruments.
+ Fix invocation of setvbuf when passed a -X flag -- I had
+ unwittingly used an ANSI C extension, and this caused
+ core dumps on some machines.
+ Diagnose self-destructive alias loops on RCPT as well as EXPN.
+ Previously it just gave an empty send queue, which
+ then gave either "Need RCPT (recipient)" at the DATA
+ (confusing, since you had given an RCPT command which
+ returned 250) or just dropped the email, depending on
+ whether you were running VERBose mode. Now it usually
+ diagnoses this case as "aliasing/forwarding loop broken".
+ Unfortunately, it still doesn't adequately diagnose
+ some true error conditions.
+ Add internal concept of "warning messages" using 6xx codes.
+ These are not reported only to Postmaster. Unbalanced
+ parens, brackets, and quotes are printed as 653 codes.
+ They are always mapped to 5xx codes before use in SMTP.
+ Clean up error messages to tell both the actual address that
+ failed and the alias they arose from. This makes it
+ somewhat easier to diagnose problems. Difficulty noted
+ by Motonori Nakamura.
+ Fix a problem that inappropriately added a ctladdr to addresses
+ that shouldn't have had one during a queue run. This
+ caused error messages to be handled differently during
+ a queue run than a direct run.
+ Don't print the qf name and line number if you get errors during
+ the direct run of the queue from srvrsmtp -- this was
+ just extra stuff for users to crawl through.
+ Put command line flags on second line of pid file so you can
+ auto-restart the daemon with all appropriate arguments.
+ Use "kill `head -1 /etc/sendmail.pid`" to stop the
+ daemon, and "eval `tail -1 /etc/sendmail.pid`" to
+ restart it.
+ Remove the ``setuid(getuid())'' in main -- this caused the
+ IDENT daemon to screw up. This required that I change
+ HASSETEUID to HASSETREUID and complicate the mode
+ changing somewhat because both Ultrix and SunOS seem
+ to have a bug causing seteuid() to set the saved uid
+ as well as the effective. The program test/t_setreuid.c
+ will test to see if your implementation of setreuid(2)
+ is appropriately functional.
+ The FallBackMX (option V) handling failed to properly identify
+ fallback to yourself -- most of the code was there,
+ but it wasn't being enabled. Problem noted by Murray
+ Kucherawy of the University of Waterloo.
+ Change :include: open timeout from ETIMEDOUT to an internal
+ code EOPENTIMEOUT; this avoids adding "during SmtpPhase
+ with CurHostName" in error messages, which can be
+ confusing. Reported by Jonathan Kamens of OpenVision
+ Technologies.
+ Back out setpgrp (setpgid on POSIX systems) call to reset the
+ process group id. The original fix was to get around
+ some problems with recalcitrant MUAs, but it breaks
+ any call from a shell that creates a process group id
+ different from the process id. I could try to fix
+ this by diddling the tty owner (using tcsetpgrp or
+ equivalent) but this is too likely to break other
+ things.
+ Portability changes:
+ Support -M as equivalent to -oM on Ultrix -- apparently
+ DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs
+ instead of using standard flags. Oh joy. This
+ behaviour reported by Jon Giltner of University
+ of Colorado.
+ SGI IRIX -- this includes several changes that should
+ help other strict ANSI compilers.
+ SCO Unix -- from Murray Kucherawy of HookUp Communication
+ Corporation.
+ Solaris running the Sun C compiler (which despite the
+ documentation apparently doesn't define
+ __STDC__ by default).
+ ConvexOS from Eric Schnoebelen of Convex.
+ Sony NEWS workstations and Omron LUNA workstations from
+ Motonori Nakamura.
+ CONFIG: add confTRY_NULL_MX_LIST to set option `w'.
+ CONFIG: delete `C' and `e' from default SMTP mailers flags;
+ several people have made a good argument that this
+ creates more problems than it solves (although this
+ may prove painful in the short run).
+ CONFIG: generalize all the relays to accept a "mailer:host"
+ format.
+ CONFIG: move local processing in ruleset 0 into a new ruleset
+ 98 (8 on old sendmail). Domain literal [a.b.c.d]
+ addresses are also passed through this ruleset.
+ CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined,
+ internet-style addresses would "fall off the end" of
+ ruleset zero and be interpreted as local -- however,
+ the angle brackets confused the recursive call.
+ These are now diagnosed as "Unrecognized host name".
+ CONFIG: USENET rules weren't included in S0 because of a mistaken
+ ifdef(`_MAILER_USENET_') instead of
+ ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik
+ of SINTEF RUNIT, Oslo.
+ CONFIG: move up LOCAL_RULE_0 processing so that it happens very
+ early in ruleset 0; this allows .mc authors to bypass
+ things like the "short circuit" code for local addresses.
+ Prompted by a comment by Bill Wisner of The Well.
+ CONFIG: add confSMTP_MAILER to define the mailer used (smtp or
+ esmtp) to send SMTP mail. This allows you to default
+ to esmtp but use a mailertable or other override to
+ deal with broken servers. This logic was pointed out
+ to me by Bill Wisner. Ditto for confLOCAL_MAILER.
+ Changes to cf/sh/makeinfo.sh to make it portable to SVR4
+ environments. Ugly as sin.
