List all the names you're an MX for in rcpthosts.  Shouldn't be difficult
to make a script to munge your zone file to produce the necessary records
and update rcpthosts if you manage your own DNS records.  If not, just
update rcpthosts whenever you tell your DNS people to add the MX records.

As I'm sure someone will tell you in more detail, you don't really want to
do a lookup for MX records pointing at you, as anyone can make such
records.
