[Mailman-Users] Help

[Farid, Tarek]

Hello,   I have installed mailman recently on a RH 7.2 linux server with postfix as my mta. Created a test list. I can get to it fine with my web browser, except for the public archives (pipermail)! This is my first problem.   My second and main problem is that when I post to the list I get the following error:   Diagnostic-Code: X-Postfix; Command died with status 2:     "/var/mailman/mail/wrapper mailcmd test". Command output: Failure to exec     script. WANTED gid 12, GOT gid 99.  (Reconfigure to take 99?)     If anyone had seen this before, please let me know how to fix it.   Thanks…   TF
