[Mailman-Users] Problem: qmail says: Failed to exec mailman wrapper: unable to determine caller's group name

[Heinrich, Maximilian]

Hi There!

After installing a Suse9.3, mailman and importing the old mailing lists
we can't use it anymore. We also tried the script that sets proper
rights to all directories and so on. Nothing helps and google doesn't
know anything about this weird message. At least to me it doesn't make
sense:

Qmail says (after being not able to do anything useful with a mail sent
to the mailing list) :

> Failed to exec mailman wrapper: unable to determine caller's group
name I'm not going to try again; 
> this message has been in the queue too long.

This is was ps says: (looks ok to me)
