[Mailman-Users] Error on test list: "/home/mailman/mail/wrapper post prueba" WANTED gid 12, GOT gid 99. (Reconfigure to take 99?)

[Gabriel Menini [F.I.S.]]

Hello!

I am installing the mailman software, because I love its web-based
administration tool.

When  I send an email to my first test list called 'prueba' the messages was
rejected.
I quote the message body:
BTW, I am running Postfix as my MTA.
