[Mailman-Users] set gid didn't work?

[Amanda]

I'm trying to send messages to my test list and they're not going through. The
log is giving the following:

Jun  4 16:49:58 tux Mailman mail-wrapper: Failure to exec script. WANTED gid
12, GOT
gid 401.  (Reconfigure to take 401?)
Jun  4 16:49:58 tux qmail: 991698598.174168 delivery 5: deferral:
Failure_to_exec_script._WANTED_gid_12,_GOT_gid_401.__(Reconfigure_to_take_401?)

The kicker is, there *is* no group with gid 401. So I'm a little baffled...
What do I need to do to fix this?


Thanks,
=)
