Fedora Core 2 is quite obsolete, being unsupported at fedoralegacy.org
since July. Do you have a published MX record, or domain pointing at
your router?

Most mail servers expect to find the mail server on port 25.

Use tcpdump, and see what the packets are saying.

Receive mail from who? You normally receive mail via your ISP, who is
probably allowing you to get the mail from their server using POP3 or IMAP
(a program like fetchmail). If you have your own domain registered, the
Internet expects to find your mail server listening on port 25.

netstat -tupan Is it listening on the eth0 interface? (Look at the
Local and Foreign addresses)
