SPF, DK, DKIM, Sender-ID, take your pick. Or use them all. :) You can do this either with explicit support of your MTA or by using SpamAssassin as a precursor to TMDA. In my experience, teaching TMDA to file or discard anything above a certain spam threshold offers benefits beyond this single case.
