This is unsafe in general use, since very many sites will send mail
from servers which are not MXs for the sender domain. If you're only
doing it for a restricted list of domains for which you know this
doesn't apply, you can use the dnsdb lookup type... I can never
remember how that works, so someone else will have to help you with
that.
