It's certainly possible with sendmail (I used to do it there with a very
hacked up .cf file reading the settings from a 'map' [aka 'hash']).  Now
I've moved everything to postfix, and there's a patch to postfix for
that, too.

Blocking at the SMTP level is MUCH nicer than leaving it to procmail:
you don't allow the spam onto your system and senders will get a bounce
(assuming their mail configuration is correct, anyway) instead of a
silent discard.  (Procmailing out bounces is bad since lots o' spammers
use bogon return envelopes so all you end up doing is filling your
outgoing queue with junk that won't be deliverable.)
