Mailman either uses SMTP or sendmail to send mail to your local SMTP server, Mailman leaves it to the SMTP server to handle distributing the mail to its recipients. If you're handing incoming and outgoing mail on the same server, you need to have port 25 open both inbound and outbound. > If im hunch is right, in the firewall, I open smtp out, pop3 in, and the > server will work.

You'll need to have some way for people to post to the mailing list - it's pretty useless otherwise. I don't know what MTA you're using - so I can't offer any specific advice on MTA security. The biggest problem when running a mail server is relaying, although most reasonable MTAs are now secured against relaying out of the box. See http://mail-abuse.org/tsi/ar-fix.html This is rather OT for this mailing list - if you still need help, try posting to your distributions security mailing list, news://comp.os.linux.security, or your MTAs mailing list or newsgroup.
