[ This comes from the "Overview" file. --r$ ]

Currently on Unix, there seems to be a preponderence of line-oriented
software.  This is most unfortunate as most of the software on Unix tends
to be pretty darn hard to use!  I believe that there is more than a slight
correlation between the two, and, since I was myself having problems using
"mailx" with high-volume mail, I created a new mail system.

In the lingo of the mail guru, Elm is a "User Agent" system,  it's
designed to run with "sendmail" or "/bin/rmail" (according to what's on
your system) and is a full replacement of programs like "/bin/mail" and
"mailx".  The system is more than just a single program, however, and
includes programs like "frm" to list a 'table of contents' of your mail,
"printmail" to quickly paginate mail files (to allow 'clean' printouts),
and "autoreply", a systemwide daemon that can autoanswer mail for people
while they're on vacation without having multiple copies spawned on the
system.

XThis is the 2.3 (USENET) version of the Elm Mail System
X
XSee the NOTICE and Instruct files for further details.
X
XIt is IMPERITIVE that all users rerun newalias after installing
XElm 2.3 when upgrading from a previous version.  Elm's behavoir
Xwith aliases could be unpredictible if this step is not performed.
X
XWhere to find more info on Elm:
X   Much discussion on Elm including interim bug fixes, work arounds
Xand future plans occurs in the Usenet news group comp.mail.elm.  Also
Xa monthly status report on Elm is posted there.  This status report
Xlists the archive sites that have the patches to Elm as well as the
Xlastest version.
X
XPatches to Elm are posted to comp.mail.elm and comp.sources.bugs as
Xsoon as they are released.  They are posted to comp.sources.unix shortly
Xthereafter, to allow time for feedback of problems in the patches.
XPatches should be available from the archive sites, or from the
Xarchive server.  Mail [e-mail] for details on how to
Xuse the archive server program.  Ask it for help.
X
XLimitations/Problems you might encounter in installing Elm:
X
X    On some Unix 5.3.2 systems, if only a runtime version of the
XO/S has been installed, not all the include files exist for compiling
Xcurses.c.  The ptem.h include file contains the window sizing structure
Xon this version.  Either comment out the window sizing code, or install
Xthe remaining include files from the development system.
X
X    If you run a nonstandard configuration of Mail, such as Xenix
Xrunning smail, Configure can get confused as to where to place items.
XBe sure and check the config.sh file for the correct placement before
Xcontinuning.  If changes are necessary, rerun Configure and fix the
Xfile before exiting.
X
X    On SCO Xenix, if you are all mail is from user anonymous,
Xthis is because the mail delivery agent should be
X/usr/lib/mail/execmail instead of /usr/bin/rmail or /bin/rmail.
X
X    On some systems, especially those based on the AT&T Port to
X286's the -O flag of the compiler produces improper code causing
Xsegmentation violations.  If this happens, recompile the code without
Xthe -O flag.  This has been seen with Microport SysV/AT type systems.
X
X    The Configuration script has been known to exceed the default
Xstack size in Unix 286 sh's.  If Configure does not run correctly on
Xthis type of machine increase the stack size and rerun it.  On
XMicroport SysV/AT machines, Configure might run correctly under ksh.
XObtain ksh from Microport (available to current version owners without
Xadditional charge) and rerun Configure using it.  Xenix 286 users may
Xhave the same problem, but they can work around it by changing the
Xstack size within the shell as reported a Xenix 286 Elm user:
X> I had the same problems as everyone else is reporting on Microports *nix under
X> SCO XENIX 2.2.1.
X>
X> The solution is simple, up the stack size for /bin/sh. I used
X>
X> # mv /bin/sh /bin/sh.old
X> # cp /bin/sh.old /bin/sh
X> # fixhdr -F 8000 /bin/sh
X>
X> This may seem a bit over the top, but I put it back after!
X>
X> # mv /bin/sh /bin/sh.rm
X> # mv /bin/sh.old /bin/sh
X>
X> Then wait till nobody is using /bin/sh.rm then
X>
X> # rm /bin/sh.rm
X>
X> That way you preserve your old shell, ( ie you don't break it ), but you
X> get to use Configure without bus errors etc.
X>
X> I hope that of use

X
X    Also on Microport SysV/AT Machines, the C compiler produces
Ximproper code for one of the arithmetic calls.  To fix this problem it
Xis necessary to reduce the complexity of the statement, as reported by
Xone of our testers here is the symptom and his patch.  Being this is a
Xcompiler bug on only one system, we make the information available, but
Xnot incorporate it in the main release.  Note, this may effect other
Xareas of Elm, and in the future, Microport may even fix this problem.

X            An Overview of the Elm Mail System
X            ----------------------------------
X
XIntroduction
X
X    This file discusses the functionality of the Elm mail system
Xand explains some of the motivation behind the various features.
X
X1. What is Elm?
X
X    Currently on Unix, there seems to be a preponderence of line-oriented
Xsoftware.  This is most unfortunate as most of the software on Unix tends to
Xbe pretty darn hard to use!  I believe that there is more than a slight
Xcorrelation between the two, and, since I was myself having problems using
X"mailx" with high-volume mail, I created a new mail system.
X
X    In the lingo of the mail guru, Elm is a "User Agent" system,  it's
Xdesigned to run with "sendmail" or "/bin/rmail" (according to what's on
Xyour system) and is a full replacement of programs like "/bin/mail" and
X"mailx".  The system is more than just a single program, however, and
Xincludes programs like "frm" to list a 'table of contents' of your
Xmail, "printmail" to quickly paginate mail files (to allow 'clean'
Xprintouts), and "autoreply", a systemwide daemon that can autoanswer
Xmail for people while they're on vacation without having multiple
Xcopies spawned on the system.
X
X2. What's New about Elm?
X
X    The most significant difference between Elm and earlier mail
Xsystems is that Elm is screen-oriented.  Upon further use, however,
Xusers will find that Elm is also quite a bit easier to use, and quite
Xa bit more "intelligent" about sending mail and so on.   For example,
Xsay you're on "usenet" and receive a message from someone on the
XARPANET.  The sender also "cc'd" another person on ARPA.  With Elm
Xyou can simply G)roup reply and it will build the correct return
Xaddresses.
X
X    There are lots of subtleties like that in the program, most of
Xwhich you'll probably find when you need them.
X
X3. What systems does it work on?
X
X    Elm was originally written on HP-UX, HP's proprietary version
Xof Bell system V, with a little BSD thrown in.  Since then, it has been
Xported to Bell, Berkeley, Sun, UTS, Pyramid and Xenix and should run on
Xall these systems without any modifications (if there turn out to be
Xmodifications, please notify the author as soon as possible).
X
X4. Does it obey existing mail standards?
X
X    Yes!  That's another of the basic reasons the program was
Xoriginally written!  To ensure that the date field, the "From:" line
Xand so on were all added in the correct format.  The program is 100%
Xcorrect according to the RFC-822 electronic mail header protocol
Xguide.
X
X5. What were the main motivating factors?
X
X    The first two I've already mentioned, but here's a (somewhat
Xpartial) list;
X
X    -  To have a mail system that exploited the CRT instead of
X       assuming I'm on a teletype.
X
X    - To have a mailer that was 100% correct when dealing with
X      network mail (ie RFC-822).
X
X    - To create a system that needed no documentation for the
X      casual user, but was still powerful enough and sophisticated
X      enough for a mail expert.
X
X    - To write a "significant" piece of software as a learning
X      experience (I admit it!)
X
X    - To find out how reasonable it is to try to modify a program
X      to meet the expectations of the users, rather than vice-versa.
X
X    - To basically correct some of the dumb things that the current
X      mailers do, like letting you send mail to addresses that it
X      could trivially figure out are going to result in 'dead.letter'
X
X    - To tie in intimately with the pathalias program output, and
X      allow users to specify machine!user or user@machine and have
X      the COMPUTER do the work of figuring out addresses...
X
X6. Is it reliable?
X
X    The mailer, in various incarnations, has logged literally
Xthousands upon thousands of hours without any problems that aren't
Xnow corrected.  As new problems arise they're dealt with in as
Xrapid a manner as possible...
X
X7. Disclaimers
X
X    The author of this program will deny all liability for any
Xdamages, either real or imagined, due to the execution of this program
Xor anything related to either the software or the system.  Furthermore,
Xthe entire system and all source within, including the presentation
Xscreens and commands, are legally copyrighted by the author, and while
Xthey can be used, and abused, for public domain systems, it will be in
Xviolation of the law if used in systems or programs sold for profit.
X
X    By installing the mailer or even extracting it from the network,
Xyou are agreeing to the above disclaimer.
X
X8. Finally
X
X    I think it's a good program, and I can cite at least 75 people
Xwho would (begrudgingly, I'm sure) agree.  You should most certainly
Xinstall the program and try it!!

X                Instructions
X                ------------
X
X                Last Update: $Date: 90/04/28 22:40:43 $
X
X
X    This file contains instructions on how to create and install
Xthe entire ELM mail system.  It should be read BEFORE any attempts
Xare made at actually creating and/or installing any of the software
Xcontained herein!
X
X    There is actually really one step needed - unpack all the shar
Xfiles and then;
X
X    $ cd <where-ever you're keeping the Elm sources>
X
X    $ sh Configure
X
X    Answer the questions of that program,, then let it create the
Xlocalized Makefiles and system definition files for you.  When it's
Xdone you can double check the configuration (or customize it further)
Xby reading the Configuration Guide and then rerunning Configure.
XThere are lots of neat features that are unique to this mailer - it's
Xworth a quick perusal at least!
X
X    Once you're happy with the localized files, you then need to
Xcreate the documentation (so there's a bit of a catch-22 that you need
Xto format the Configuration guide before you are happy with the
Xlocalization but can't do that until you're happy with the
Xlocalization...oh well).
X
X    $
X
X    $ make documentation
X
X    When that's done, or even if it fails (don't worry too much about
Xit), do the following:
X
X    $ make all > MAKELOG 2>&1 &
X    $ tail -f MAKELOG
X
X    (if you're in "csh", substitute: "make all >& MAKELOG &")
X
XThis will take a fair while, so it's recommended that you go and eat
Xlunch or play a game for a while!! (alternatively, spend lots of money
Xon a really FAST machine and blink your eyes a few times...)
X
XAssuming there are no errors during compilation (we'll have to assume
Xthat for the moment) you should now be able to list the directory "bin"
Xand find the following files:
X
X  answer        checkalias     filter         messages      printmail
X  arepdaemon    elm            frm            newalias      readmsg
X  autoreply     fastmail       listalais      newmail
X
Xnext, you can install all the software on your system by;
X
X    $ make install
X
XNote: On some systems the mailer runs as setgid mail to have the ability
Xto WRITE to the mail directory (for lock files).   If you have a different
Xscheme at your site, feel free to set it up to use that instead.
X
XFinally, we're just about done!   The final checks can be made
Xby the following commands:
X
X    $ elm -z
X
Xshould say "no mail" if nothing's in your incoming mailbox or should
Xstart up the Elm program if there is, and
X
X    $ elm -f test/test.mail
X
Xshould read in EIGHT messages from various people.  While here, try to
XA)lias C)urrent message for each of the eight messages to confirm that
Xthe reply/address system is working okay.  Now Q)uit without having
Xmarked anything for deletion...answer the questions accordingly.
X
XIf you get this far you're in wonderful shape!  In fact, you're done!
X
XCongratulations!  You've just installed one of the best electronic mail
Xsystems available today on your machine (if I say so myself!)
X
XIF UPGRADING FROM AN EARLIER VERSION OF ELM, even 2.3 beta, it will
Xbe necessary for all users alias files, as well as the systems alias
Xfile, be upgraded to the new format.  Also some error checking of
Xalias files has been added.  All users should run the newalias command.
X
XHANDY HINTS:  If you want to create a print of the entire set of
Xsources, including this file, use the command:
X
X    $ make listing
X
XAlso, if you have a number of machines on a network, you can rlogin
Xto the remote machine and then do a remote install (after checking
Xto ensure that the networking copy method in the Makefile under the
Xtarget "remote-install" is correct) by typing:
X
X    $ make -f <remote Makefile> REMOTE=<remote file system> rmt-install
X
X(for example, if we had installed the system on machine "machx" and
X wanted to install it on "machy", with the Makefile in /src/Elm on
X "machx", we could type from "machy";
X     $ make -f machx:/src/Elm/Makefile REMOTE=machx: rmt-install
X to have it install the system on machine y!)
X
XThat's it!

X
XAdd BSD style screen sizing when the IOCTL calls exist.
X
XRemove direct access to the L.sys/Systems file and only use uuname.
X
XAdd -v option for Elm version and options information.
X
XAllows specifying the temp directory to be used by Elm.
X
XAllow for restricting shell escapes from Elm.  (But of course, not
Xfrom any pager or editor Elm would invoke)
X
XAdd PID type locking to the lock file.
X
XMake Elm confirm an x command if changes pending, allow X to be the
Xold non confirming x command.
X
XAllow for disabling the X-Mailer header if desired.
X
XComplete revamp of Configure using new Metaconfig modules.
X
XAdd some checking for space problems and force an emergency exit in those
Xcases.
X
XAllow the alias file to be used across heterogenous networks by
Xkeeping it in network byte order if NFS is available.
X
XAdd support for MMDF style mailboxes.
X
XAliases are now case insensitive as per survey results
X
XRecursive aliases now work again.
X
XAnd many bug fixes.
