Larry,
Best technologies (as I see them, but I am not omniscient, of course)
are those that do scoring. E.g. naving some word NN might not alone
be considered spam-signature, but it might increase score, and once
the score exceeds arbitrary treshold (lower with short messages?),
the message is considered spam, and rejected.
Some recent TEXT/PLAIN spams have been encoded in BASE64 or ingenous
QUOTED-PRINTABLE to avoid several common Perl-RE pattern using filters.
I think there are several free codes of this kind available, but my time
has been chronically over-subscribed to do radical things like taking
this kind of codes into use.
