[Mailman-Users] Problem

[Nilza Penha Silva]

I use Postfix for my MTA and when I send mail to the list I get back mail saying:

                        The Postfix program

<[EMAIL PROTECTED]>: Command died with status 2:
    "/usr/local/mailman/mail/wrapper post prodemge". Command output: Failure to
    exec script. WANTED gid 1, GOT gid 60001.  (Reconfigure to take 60001?)

What does it mean? Why does it want GID 1?
What I have to do to solve this problem?

Thanks,
