[Mailman-Users] confused by group mismatch

[Chad Rebuck]

I've had a list running fine for months, but after I restored my
complete disk from backup I am getting this message when posting to
the list:


<a2-16v-list at mail.a2-16v.com>: Command died with status 2:
   "/usr/lib/mailman/mail/mailman post a2-16v-list". Command output: Group
   mismatch error.  Mailman expected the mail wrapper script to be executed as
   group "80", but the system's mail server executed the mail script as group
   "mailman".  Try tweaking the mail server to run the script as group "80",
   or re-run configure,  providing the command line option
   `--with-mail-gid=mailman'.


I've checked the faq here -
http://wiki.list.org/display/DOC/Understanding+group+mismatch+errors+-+how+mailman+implements+security

I've also searched around and I'm not really understanding why the
group "80" isn't translated to mailman?  Ideas?

mailman exists in /etc/group

mailman:x:80:

mailman exist in /etc/passwd

mailman:x:80:80:GNU Mailing List Manager:/usr/lib/mailman:/sbin/nologin


I don't understand what the problem is.  I didn't want to just re
configure mailman without first asking what else to check.  After all
this was working for many months prior to the hard drive restore.

Thank you.
