No MX records BUT having an A record gives you an implicit MX record that is essentially just the A record.
Having MX records should remove the A record completely from being considered for mail delivery. Further, I believe there really is a "standard' to publish a blank MX record at priority 0 but I think I heard about it from Jan-Pieter Cornet. Anyone know if this has a real RFC or anything?
