[I sat on these for a bit, this being the fourth "final" version I've received.
Looks like this time it's for keeps. ++bsa]
Okay, here it is (finally). Patches for using Smail under SCO Xenix.
Many people have got smail running under Xenix, but their schemes usually
break Micnet mail and ignore pipe aliases as supported by the standard
Xenix mail system. My patches don't replace Xenix mail, they work with it.
And besides, they look nice. :-)
So here's the sharchive. "Shar and enjoy."
#! /bin/sh
# This is a shell archive, meaning:
# 1. Remove everything above the "#! /bin/sh" line.
# 2. Save the resulting text in a file.
# 3. Execute the file with /bin/sh (not csh) to create the files:
# X.README
# X.patches
# Makefile
# execm.c
# install_smail
# This archive created: Thu Jan 7 13:58:34 1988
export PATH; PATH=/bin:$PATH

echo 'shar: extracting "X.README" (4621 characters) '
if test -f 'X.README'
then
echo 'shar: will not overwrite existing file "X.README" '
else
sed 's/^X//' << \SHAR_EOF > 'X.README'

X
XThis file describes how to use the enclosed smail 2.5 patches for SCO Xenix
XSystem V. (They may work with non-SCO Xenix.)
X
XTo use these patches, you need either (1) Larry Wall's "patch" program, or
X(2) lots of patience while you apply these changes by hand.
X
X
XFor users of my earlier smail patches:
X
X I posted some early smail patches in comp.unix.xenix and
X alt.sources in December '87. If you are using those patches, you
X should get rid of them and USE THESE PATCHES INSTEAD.
X
X Why?
X
X 1. Cleaner mods (only important things have been changed).
X 2. Better comments.
X 3. Explicit support for Micnet/Xenix-Net.
X 4. Support for /etc/systemid file (no need to relink your
X kernel to change your machine name).
X
X
XInstallation:
X
X 1. Find your original, untouched smail 2.5 sources. Copy these
X to a new directory. (We'll call it "/usr/src/xsmail".)
X If you don't have your original sources, some (or many!)
X patches may fail, possibly introducing problems.
X
X 2. Unpack this sharchive and move the files in this sharchive into
X /usr/src/xsmail. This will overwrite the distributed Makefile,
X so you may want to rename the original Makefile first.
X
X 3. Change to /usr/src/xsmail and run "patch <X.patches". This
X does the hard work of changing source files.
X
X This step will leave ".orig" files lying around. You may
X remove these at any time, but I'd leave them until installation
X is complete just to be on the safe side. If any patches fail
X -- which should only occur if you're starting with modfied
X sources -- the failed patches will be written to ".rej" files.
X
X 4. Examine defs.h and modify it as necessary for your machine(s).
X Specifically, if you're running Micnet or Xenix-Net, you'll
X probably want to uncomment "#define MICNET". (Or you can
X include "-DMICNET" in the CFLAGS in the Makefile.)
X
X 5. Run "make" to make smail and execm, or if you prefer, run
X "make all".
X
X 6. >As root<, run "./install_smail".
X
X
XThe above steps should result in:
X
X /usr/bin/rmail moved to /usr/bin/rmail.x and never used again.
X
X Smail installed as /usr/bin/smail with a link to /usr/bin/rmail.
X
X /usr/lib/mail/execmail moved to /usr/lib/mail/execmail.x. Smail
X then uses execmail.x for delivering local mail. (If you compile
X smail with MICNET defined, then execmail.x is used for delivering
X _all_ mail, not just local mail.)
X
X The program execm.c installed as /usr/lib/mail/execmail. This
X "fake" execmail just parses its arguments and overlays itself with
X smail, which does all the work. (The /bin/mail program uses
X execmail, so we can't ignore it. I would have just linked
X /usr/bin/smail to /usr/lib/mail/execmail, but their arguments are
X different.)
X
X
XNotes on aliasing:
X
X The normal Xenix aliasing mechanism is still intact. (You know,
X /usr/lib/aliases, maliases, and faliases.) In addition, smail
X aliases using the file /usr/lib/mail/saliases. This file has a
X format which is almost, but not quite, entirely unlike the Xenix
X aliases file. See the smail "aliases.c" for some hints. The main
X difference is that you can include a name in parentheses after the
X alias:
X
X postmaster: chip (mail administrator)
X rick: rick at uunet.uu.net (Rick Adams)
X
X The nice thing about having two alias files is that smail's aliases
X can be internet-style addresses ("user at domain"), and execmail's
X aliases can be pipes ("|/usr/lib/news/uurec"). If you use Micnet,
X the network utilities will stomp on the Xenix aliases file but
X leave the saliases file untouched.
X
X
XNotes on the use of /bin/mail:
X
X If you want to use Internet-style addresses with /bin/mail, you
X have to add the line "set execmail" to /usr/lib/mail/mailrc.
X Otherwise, /bin/mail assumes that addresses without bangs must be
X valid local users. Of course, you can use the bang notation with
X domains and /bin/mail will always be happy.
X
X If you do any significant amount of mail work, forget /bin/mail and
X use Elm. It's the best thing since System V. :-)
X
X
XOne final comment:
X
X I'd like to have some idea of how widely used these patches are.
X So when you get it working -- or if you can't! -- drop me a line
X and tell me about it. (My address is ateng!chip. If you can't find
X a valid path, try going through codas or uunet.)
X
X
XObligatory quote:
X
X "INVESTIGATE your point of view, don't just dogmatize it!
X Reflect on it and re-evaluate it. You may want to change
X your mind someday."

X+ ** Modified for SCO Xenix by Chip Salzenberg (chip at ateng.UUCP).
X+ ** Released to Usenet on 01 Dec 1987.
X+ ** Further modified 23 Dec 1987.
X+ **
X+ ** Additions:
X+ **
X+ ** EXECMAIL is defined as the renamed /usr/lib/mail/execmail.
X+ ** Under Xenix, this is the local delivery agent.
X+ **
X+ ** SMARTMAILER is now automatically defined if either SENDMAIL
X+ ** or EXECMAIL is defined. This is useful for code that depends
X+ ** on properties that these programs have in common (automatic
X+ ** bouncing of failed mail, for example).
X+ **
X+ ** MICNET should be defined if Micnet or Xenix-Net is in use.
X+ ** In this case, execmail is used for _all_ mail, which allows
X+ ** the automatic routing of UUCP mail to a gateway. However,
X+ ** execmail sends one file per recipient, even if the recipients
X+ ** are all on the same (remote) machine. This is not exactly
X+ ** a bug; it just increases UUCP connect time. I personally
X+ ** leave MICNET undefined.
X+ **
X+ ** HOSTFILE is the name of a file containing the hostname.
X+ ** Under Xenix, this is "/etc/systemid". HOSTFILE overrides
X+ ** UNAME/GETHOSTNAME.

X# Shell script to install smail in a Xenix System V system.
X#
X# Written by Chip Salzenberg (chip at ateng.UUCP).
X# Released to Usenet on 01 Dec 1987.
X#
X# Note that this script renames the standard Xenix rmail and execmail
X# programs to rmail.x and execmail.x respectively. If those `.x' files
X# already exist, then no renaming takes place, so you can run this script
X# more than once without losing those renamed programs.
X#
X# BTW, be sure to test everything thoroughly; a broken mail system is
X# sure to upset any users on your system.
