There are two immediate things to check:
1) I know you said it, but please verify the mailman uid and gid:
# id mailman
2) Postfix has a "feature" which is it will run the commands found in an
alias file under the identity of the alias file. What is the owner/group
of the alias file:
# ls -l path-to-mailman/data/aliases
if its group does not match what the mailman wrapper is configured for
you'll get group mismatch problems because postfix will attempt to run
the mailman alias commands under the group belonging to the alias file,
not to the mail_owner in postfix's main.cf file. I think I recall a
config variable to turn the postfix behavior off, but you should not do
that because mailman should be creating the alias file and hence it
should match the uid/gid, but if you hand created it, then all bets are
