[Mailman-Users] error, message

[Ivy Wang]

I setup a maiman list. But when I try to send message to it, I got:

I'm sorry to have to inform you that the message returned
below could not be delivered to one or more destinations.

If you do so, please include this problem report. You can

			The Postfix program

<testinglist at abc.com>: Command died with status 2:
    "/home/mailman/mail/wrapper post testinglist". Command output: Failure 
to
    exec script. WANTED gid 556, GOT gid 99.  (Reconfigure to take 99?)

when I reconfigure it with-mail-gid=556, it will tell me :

<testinglist at abc.com>: Command died with status 2:
    "/home/mailman/mail/wrapper post testinglist". Command output: Failure 
to
    exec script. WANTED gid 99, GOT gid 556.  (Reconfigure to take 556?)

I'm really confused. Any help would be appreciated. Thanks.
