Have you tried running Mailman's bin/check_perms?

Here's what you should have in the way of ownership and permissions.
Group should be _mailman on everything. 'owner' doesn't matter except in
the one case where I indicate _www. SETGID bits are important.

drwxrwsr-x  owner _mailman  /path/to/mailman

drwxrwsr-x  owner _mailman  /path/to/mailman/archives

drwxrwsr-x  owner _mailman  /path/to/mailman/archives/

drwxrwsr-x  owner _mailman  /path/to/mailman/archives/public
                             and only symlinks in this directory

drwxrws--x  owner _mailman  /path/to/mailman/archives/private
drwxrws---  _www  _mailman  /path/to/mailman/archives/private

If you want to protect against access to private archives by local users
of the machine, you want the latter. Otherwise the former is fine.

drwxrwsr-x  owner _mailman  /path/to/mailman/archives/private/*

And similarly for subordinate /path/to/mailman/archives/private/*/*

-rw-rw-r--  owner _mailman  for most files subordinate to

Again, SETGID bits are important.
