Keep in mind that the abscence of an MX record doesn't make a hostname
an invalid delivery address. The default (which is quite servicable in
most cases) is to attempt delivery to the A address. That said, I
believe that one of the perl modules in the ports collection will help
you with what you want, probably the DNS module.
Good luck,
