I don't have time to report spam one by one.  We reject 1.2 million
a day and still get 2,000 spam reports a day.  I would implement
something automated.  We look up URL hostnames in SURBL, URL IP
addresses in Spamhaus, and under consideration now is looking up
PTR for the IP and scoring as possible spam if it points to yahoo.
The only question weighing how useful that test would be against
the time to do DNS lookup.
