* @(#)READ_ME 8.9 (Berkeley) 1/26/94
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.
The sendmail manual pages use contemporary Berkeley troff macros. If
your system does not process these manual pages, you can pick up the
new macros in a BSD Net/2 FTP site (e.g. on FTP.UU.NET, the files
/systems/unix/bsd-sources/share/tmac/me/strip.sed and
/systems/unix/bsd-sources/share/tmac/*).
The strip.sed file is only used in installation.
After installation, edit tmac.doc and tmac.andoc to reflect the
installation path of the tmac files. Those files contain pointers to
/usr/share/tmac/, and those pointers are not changed by the `make
Rename the existing tmac.an to be tmac.an.old, and rename tmac.andoc
tmac.an will choose between tmac.an.old, your old macros, or tmac.doc,
which are the new macros, so that both the new man pages and the
existing man pages will be translated properly.
I'm also told that the groff distribution from MIT has a tmac.doc
macro set that is compatible with these macros.

There are some things that may behave somewhat differently.
For example, the rules governing when :include: files will
be read have been tightened up for security reasons.

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.
Be sure you remove ndbm.h and ndbm.o from the db distribution. These
will cause problems with sendmail because sendmail already understands
about NEWDB and NDBM coexisting.
This version of sendmail notices and reports certain kinds of SMTP
protocol violations that were ignored by older versions. If you
are running MH you may wish to install the patch in contrib/mh.patch
that will prevent these warning reports. This patch also works
with the old version of sendmail, so it's safe to go ahead and
The Makefiles in this release use the new Berkeley "make" that is
available in BSD Net/2 and 4.4BSD. If you are using this version
of make, you may notice one or two places where the Makefile includes
"../../Makefile.inc". This file is not included with the sendmail
distribution because it's not part of sendmail. However, it is,
# @(#)Makefile.inc 8.1 (Berkeley) 6/6/93
The other directories should all have Makefile.dist files that work
on the old make, albeit without all the niceties included.
You can also get a new Berkeley make from the Net2 release (available
on many public FTP archives). This version should also interpret old
Makefiles, so you could drop it in as your default make.

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
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.
src Source for the sendmail program itself.
test Some test scripts (currently only for compilation aids).
