Many people think that you need an MX record to receive mail. This is incorrect." ... "MX records serve a clear purpose: they let you specify that you want mail to a machine to be handled by another machine." ... "when there are multiple MX records, remote mail servers will first try to deliver mail to the server with the lowest preference.

The bastards at Road Runner are blocking me from sending mail to them because I have a residential IP address. Since I won't use the SBC mail server as my outgoing server, I had to call SBC and ask them to add a P record to my DNS information. The P record allows reverse lookups of my IP address to return the name "mail.pdrap.org" which should now match the domain produced from a forward DNS request. When this change propagates to the root nameservers, I'll give Road Runner a call and tell them to unblock my IP address.
