Eric, Not knowing what all you've got configured exactly, here's a couple of possible guesses to weed out the basics.
Can you do a reverse DNS lookup on your mail server? In other words, perform a whois on the IP address and get a legit domain name. Many servers require this in order to keep out obvious spammers. You should also triple check and make sure that you have SMTP open to come back to you from the outside world. SMTP requires open ports coming in as well as going out. Check your TCP Wrappers and whether or not IPFW or IPFilters is in the mix.
