Can you add the uid that your MTA is running as to the group 'majordomo'?
If running sendmail, check your /etc/sendmail.cf for a DefaultUser
setting; that uid would then be added to the majordomo group.  Then
make sure that everything is set 640.

Haven't thought about this too much; anyone think of any ramifications
to this?
