bin/check_perms will help. I don't think mailman:mail is correct. The
user is not important, but the group should be Mailman's group (the
setting for MAILMAN_GROUP in Defaults.py. Run

bin/check_perms -f

as root. That should make group and mode correct.

See the FAQ at <http://wiki.list.org/x/tYA9>.

Where are your aliases?

The mail wrapper is compiled to to expect to be invoked by the 'mail'
group. Postfix will invoke the wrapper as the user and that user's
primary group corresponding to the owner of the aliases.db file in
which the pipe command was found. I.e., if the aliases.db file is
userx:groupy, postfix will invoke the wrapper as userx:groupx where
groupx is userx's primary group.
