Mailman expected the mail wrapper script to be executed as group "mailman", but the system's mail server executed the mail script as group "nobody". Try tweaking the mail server to run the script as group "mailman", or re-run configure, providing the command line option `--with-mail-gid=nobody'.>'

See the FAQ at <http://wiki.list.org/x/4030645>.

Note that with Postfix, the pipe to the mail wrapper will be executed as
the user that owns the aliases.db file in which the alias is found.

If you have Mailman/Postfix integration configured this will be
/path/to/mailman/data/aliases.db which chould be owned by 'mailman'.
