general question about failed DNS request when looking up MXs

Okay, here's a general question for the group at large:

You are doing an MX request to resolve an address that
you need to send to.  You get back a Server Error (RCODE=2)
or an illegal return code (RCODE=6..15).  What is the best
thing to do to try and resolve this?

regards,
Jack
