[Mailman-Users] Mailman not sending mail

[Jeremy Gilbert]

I have a new Mailman server running Mailman 2.1.3 with postfix on
a Slackware 9.1 machine.  Postfix is working great.  I can send
and receive mail to any local account on the list server.

My problem is that no e-mail sent to any of the lists I've created
is forwarded, I cannot send invitation e-mails from the admin
pages and the list owners never receive messages when lists are
created.  Mailman does not send mail to either outside addresses
nor addresses on the list server.

Here is what shows up in my /var/log/maillog when it receives a
message that should  be forwarded to a list:  (I've sanitized it)

<end of /var/log/maillog>

There are no other messages that show up in this log or any other
log in /var/log.  This my first time using Mailman, so I don't
know if there are log files hidden anywhere else.

I did have a problem with Mailman choking on groups because
postfix was running as with gid "nogroup" and Mailman expected gid
"mailman."  I re-installed Mailman with the group "nogroup," but I
don't know if that caused more problems than it fixed.

Please let me know if you need more information or have any ideas
for a solution.
