[Mailman-Users] Tricky admin_immed_notify problem

[george bannerman]

Hi all--

I've got a tricky problem on my mailman server.  Right now, I have
admin_immed_notify set to yes, but I'm not getting notifications when there
are emails to approve.  I'm also not getting the once-a-day "# list
moderator request(s) waiting" either.  "Forward messages (individually) to:"
doesn't work.  They all mysteriously stopped last Friday.

I'm running Exim version 4.50 #1, Mailman 2.1.5,  Python 2.3.5, and Linux
version 2.6.16.13-xenU (Red Hat 4.0.2-8 running on Xen).

I rebooted the server ("have you tried turning it off and turning it on
again?") and the restarted the exim daemon and ran check_perms, to no avail.

I can email listname-owner (and it goes through), I can send email from the
server, and list emails go out to the lists just fine.  It only appears to
be the administrator notifications and the forward messages individually to
that are affected.

I looked at FAQ 4.73:

http://wiki.list.org/display/DOC/4.73+How+do+I+debug+smtp-failure+problems+-+delivery+to+user-example.com+failed+with+code+-1-+and+Low+level+smtp+error-

I can telnet into my SMTP port and send mail.
I looked at the MTA logs and they seem fine.  (They're below.)
I'm not running Python 2.4, so I can't do the error log trick

I looked at FAQ 6.14:

http://wiki.list.org/pages/viewpage.action?pageId=4030722

I don't get any errors when I run the two python scripts interactively as
the mailman user.

Here's what I'm getting in /var/lib/mailman/logs/smtp-failure:

Feb 25 13:54:52 2009 (1052) delivery to administrator at example.com failed

Here's what's in /var/log/exim4/mainlog:

(These are for a different message, but are representative.)

There doesn't seem to be anything in rejectlog.

I've tried changing the list administrator to a different email address by a
different provider, but that doesn't seem to change anything.

Help?

Best,

george
