My bad on that one.  My mind was thinking "send the spam back to the
spammer" and not "what if my server goes down?"  Then I lost power
longer than the UPS could keep up.  While I was out of town... and
outside of cell coverage (in the woods camping).  Whoops.

Now if I knew of a good target... I'd re-implement it in a heartbeat.  A
LOT of spammers do, in fact use the higher number MX record.  Not the
smarter ones, but there are enough dumb ones to make it worth while to me.
