Planed next version: Elm 2.4
Current Elm 2.4 status: In development
Expected release date: not before September 1, 1991 (Likely Fall 1991)
As of release 2.1, Elm is now being developed by a cooperative venture
of volunteers loosely being called the Elm Development Group. There are
approximately 40 developers and an additional 16 testers, participating
at various levels of activity.
Comments, bug reports, feature requests, etc. should be sent to
elm@DSI.COM. I try to ack most reports, but over 60% fail due to
invalid addresses. Note, I strip your address to name@fqdn or name@site
before replying.
New releases will be posted to comp.sources.unix, patches will be posted
to comp.sources.bugs. After patches have been proven and out for a
while, they will be posted to comp.sources.unix. Patches are available
from the archive server at DSI.COM. The complete release as of the
current patch level is available via anonymous uucp from dsinc. Also
available via anonymous uucp are postscript output files of the current
documentation. This service is provided for those sites that have
postscript but do not have di-troff. Instructions for obtaining files
via anonymous uucp from dsinc are also available from the archive
server. Elm is too large to mail, don't bother asking. Also don't
mail me asking for me to send you patches, I won't. Use the archive
server. The archive-server will not respond to users named root,
daemon, or postmaster to prevent loops. Please do not use those names
for archive requests. PLEASE do not send archive requests to elm@dsi.com.

Starting with release 2.2, the Elm Development group will attempt to
provide official patches to the release version to fix problems reported
at the same time we are working on the next release. Also starting with
release 2.2 a list of known problems will be published in this posting.
Known bugs in Elm 2.3 PL11:
The following are from the Elm 2.4 "To.Do" list that are
considered bugs, not enhancements, that have not yet been done. Items
which are enhancements are not listed here. It is our intention to
release changes to 2.3 for some, but not necessarly all of these. Some
of these will only be fixed in 2.4. (It depends on how extensive the
change is to fix it, and what else it ties into in the 2.4 work).
Items marked fixed will be deleted from the list on the next posting.
1. General bugs and configuration bugs
GB01 The ordering of some sets of configuration questions could
be improved. In some cases, the answer to a later question
renders an earlier question moot. In such cases, the latter
should proceed the former so that the former would only be
asked if need be. This occurs with many of the configura-
tion questions that deal with the domain routing and
pathalias databases, appending the hostname and internet ad-
dress style, etc.
GB02 All programs need to use the same algorithm elm(1) and
frm(1) use in establishing the user's id and the user's in-
coming mailbox.
GB03 RFC822 should be obeyed with regards to the recommended (but
not obligatory) order of message header lines. Currently
filter(1) and elm(1) put Subject: first because of a problem
with some USG versions of rmail(1). Some USG versions of
rmail(1) will put a null line before the header lines,
thereby making them text body instead of header, if either
the Subject: header line is not first or rmail(1) isn't
called with a -s flag. The set of rmail(1)'s that tolerate
the -s flag is a superset of the rmail(1)'s with this ``Sub-
ject: first'' requirement, but not all rmail(1)'s tolerate
-s. Therefore we need to find a way that Configure can
determine if the rmail(1) on the system will tolerate the -s
flag.
GB09 All addresses need to support both an escape character and
quoting the name portion to allow for illegal chars and
blanks.
GB10 [next item goes here]
2. Elm(1) bugs
EB02 Encryption is not fully implemented in ELM. In elm(1) we
have the following problems:
When `b' (bouncing) a message or `f' (forwarding) a message
without editing, an encrypted section of text in the origi-
nal message wrongly gets encrypted a second time. The func-
tion that looks for encryption delimiters needs to know to
ignore them in these situations.
When `p' (printing) or `|' (piping) a message, an encrypted
message does not get decrypted. This is because elm(1) in-
vokes readmsg(1) to pull the message out of the folder and
readmsg(1) does not deal with encryption at all. Even if we
gave readmsg(1) the ability to decrypt messages, we'd still
have problems because readmsg itself would have to prompt
for the decryption key. Now if we were printing or piping a
set of tagged messages, readmsg(1) would have to prompt for
decryption keys for each message individually. In doing
that readmsg(1) would have to indicate which message of the
set it was working on. This would be difficult since
readmsg(1) uses actual ordinal message position in the fold-
er, and that would be confusing if the user has folders
sorted in other than mailbox order: the message numbers
wouldn't match up. The solution therefore involves replac-
ing readmsg(1) with a new function in elm(1) to handle the
`p' or `|' commands, and this function would need to detect
the encryption delimiters and prompt for the decryption key.
Furthermore, readmsg(1) should get enhanced to deal with en-
crypted text, or else carry a disclaimer that it doesn't
work on encrypted text.
When including the text of an original message for a `r'
(reply) or `f' (forward), encrypted sections do not get de-
crypted first, resulting in decrypted text inside the in-
clude text. This means that the elm(1) function that in-
cludes text of an original message must detect encryption
delimiters and decrypt encrypted text before including it in
a reply or forwarded message.
EB10 There is an inconsistency in the format of the domain rout-
ing database as presented by the documentation and the
elm(1) code. Whichever is wrong needs to be corrected.
EB11 Some terminals with multipage memory do not scroll correct-
ly. It was recommended that elm(1) use termcap ti and te
values, but this bug may need to wait until we convert
elm(1) to use standard curses.
EB14 On the header editing screen, error messages that appear as
a result of user input should linger on the screen until the
user enters the next command, as happens on the index
screen. Currently they disappear too quickly to be read.
EB21 System_call() in src/syscall.c presumes that a system has
SIG_CONT because SIGTSTP is defined. On CCI systems this
may be wrong and a better check is the existence of the file
/usr/lib/libjobs.a.
EB25 If elm is replying to a message and considers From: lines
valid and resolves pathaliases, if the reply path from the
From: line could not be resolved, elm should report the er-
ror and ask the user if the "From " lines should be used in-
stead.
EB26 When using an address of the form "node!user@domain" and
having Elm convert it to an all ! address, RFC976 states
that the proper address should be domain!node!user, but Elm
translates that to node!domain!user.
EB30 Deletion of an alias with multiple alias names does not
work. The alias is not deleted.
EB31 Return addresses are not checked in the same way that manu-
ally entered addresses are checked against the pathalias da-
tabase, and this sometimes allows a bad address to be used.
EB36 When Elm is configured not to look at the password file for
full name information, it sometimes places the user name in
()s as the comment in addition to the full name.
EB40 If reading an alternate folder and all messages are marked
for deletion and a resync is performed, the folder is delet-
ed and Elm exits saying it cannot open the folder. [par-
tially fixed in PL 6]
EB41 [next item goes here]
3. Utilities bugs
UB02 Newmail(1) displays a null "From" when a message does not
contain a From: header line. It needs to be able to parse
the return path and display the "last two words" of it, just
like elm(1) does when it encounters a message without a
From:
UB07 Arepdaemon has a bad security hole because it does not check
to see if the user can read the file used for reply.
UB08 The move_left function in arepdaemon.c does not work for a
move of 1 byte. [fixed in 2.4]
UB09 Autoreply.c tries to unlink the file "/etc/autoreply.data"
when there is only one entry in it and does not check the
return value of unlink. This can have bad repercussions if
the unlink fails because the program nevertheless reports
success.
UB10 Readmsg doesn't understand continued header lines and there-
fore doesn't list all the "To" header, for example, if
presented on more than one line.
UB12 X.400 now also uses the = in its addresses, newalias was
changed from : to = due to X.400, but now even = is not
good for a delimiter. Newalias needs to have an escape
mechanism for its addresses. This needs to be coordinated
with GBxx. [fixed in 2.4]
UB13 If filter is run on a system that allows multiple delivery
agents, that can start up multiple copies of filter,
delivery of messages can get intermixed. Filter needs a
complete interlocking to prevent this.

An Overview of the Elm Mail System
----------------------------------
1. What is Elm?
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.
2. What's New about Elm?
The most significant difference between Elm and earlier mail
systems is that Elm is screen-oriented. Upon further use, however,
users will find that Elm is also quite a bit easier to use, and quite
a bit more "intelligent" about sending mail and so on.
3. What systems does it work on?
Elm was originally written on HP-UX, HP's proprietary version
of AT&T System V, with a little BSD thrown in. Since then, it has been
ported to AT&T, Berkeley, Sun, UTS, Pyramid and Xenix and should run on
all these systems without any modifications.
4. Does it obey existing mail standards?
Yes! That's another of the basic reasons the program was
originally written! To ensure that the date field, the "From:" line
and so on were all added in the correct format. The program is 100%
correct according to the RFC-822 electronic mail header protocol
guide.
