The normal cause of this with Postfix is having Mailman's aliases in
more than one file. When Postfix finds an alias that pipes to a
command, it runs the command with user/group equal to the ownership of
the aliases.db (or whatever it's name is) in which it found the alias.

So I'm guessing you have some Mailman aliases in Mailman's data/aliases
and data/aliases.db files which belong to group Mailman and other
Mailman aliases in /etc/postfix/aliases and /etc/postfix/aliases.db
which belong to group nobody.

The best fix is to put all Mailman's aliases in Mailman's files and
reconfigure --with-mail-gid=mailman.

Running bin/genaliases should fix all Mailman's alias files which may
actually be OK anyway, but you still will need to remove any Mailman
aliases from /etc/postfix/aliases and run postalias.
