[Mailman-Users] Mailman's Host Name & sendmail's Virtual Users

[Jon Carnes]

The DNS mx records for cinemastudies.org and tcf.ua.edu must both point
to your mailserver.

Your Mailserver must have both domains setup as local names
(/etc/mail/local-host-names -- or something like that).

You might also want to put the domain names in your /etc/mail/access
file with the keyword allow.

Good Luck - Jon Carnes
