[rt-users] Sendmail error piping to RT alias

[Andrew Ludwar]

RT is up and running fine, working via SSL, and I can create tickets fine
via the web GUI.  However the problem lies in creating a ticket via email.
I've exhausted the RT wiki, the mailing list archives, and a few other unix
forums looking for an answer.

I am using RT 3.6.7, running on Solaris 10.  (SunOS HOSTNAME 5.10
Generic_127111-11 sun4u sparc SUNW,Sun-Fire-V215).  I am using Apache
1.3.27.  MySQL 5.0.51a, FastCGI 2.4.6, OpenSSL 0.9.7g, Sendmail v. 8.13.8,
and Perl 5.8.4.

I send mail via the command line:

"sendmail -v General" (General is the name of an alias in /etc/mail/aliases,
newaliases has been run also)

# sendmail -v General
Test

and the mail doesn't get piped to RT.      /var/adm/messages shows:

Aug 21 14:26:16 vpd1tst1no sm-mta[8091]: [ID 801593 mail.info]

Now I understand sendmail uses its restricted shell when an alias instructs
it to pipe to a program. Sendmail is configured to use smrsh, and I have
placed a symlink and/or copy of rt-mailgate in /var/adm/sm.bin....([ z a z z
y b o b . c o m ] FEATURE(`smrsh',
`/usr/lib/smrsh')dnl<http://www.zazzybob.com/smrsh.html>)
which is sendmail's authorized programs directory. But still the above error
occurs.

I've reconfigured sendmail.cf to use /bin/bash and /sbin/sh instead of
/usr/lib/smrsh instead, without success. Permissions on smrsh look okay as
far as I know. I still get the same result...just now with the different
shell reference:

Also, I removed all references and copies of rt-mailgate from the
/var/adm/sm.bin dir, just to see if smrsh or sh actually makes it to the
check of that dir, and it does not give me any errors relating to rejecting
rt-mailgate because its not in the proper dir.

(That error is usually: smrsh: /var/adm/sm.bin/rt-mailgate: not found)

It seems it's an error before any of that happens. I've checked my $PATH to
make sure it can find /bin/sh or /bin/bash (even though its pretty hard to
miss those).... and I'm out of ideas.  /etc/mail/aliases is configued as so:

General: "|/usr/local/rt3/bin/rt-mailgate \
          --queue General --action correspond \
          --url https://localhost/"

general-comment: "/usr/local/rt3/bin/rt-mailgate \
         --queue general --action comment |
         --url https://localhost/"

I am able to send mail locally via sendmail, but can't get it to pipe to RT
properly.  This may be a sendmail configuration problem, but I cannot tell
for sure.  All shells do infact exist in /sbin/sh, /bin/bash,
/usr/lib/smrsh.  Am I missing any system variables?

Any ideas team?  I'm absolutely stumped.

Any feedback would be greatly appreciated.  Thanks!
