I've written a milter... it's in early stages, and seems to be causing
authentication problems, but (as SA did), I've started with simple
static pattern matching. I'll fix the bugs and add statistical analysis,
then distribute.

The good news is that it pretty much stopped dead my virus spam problem
(killing the connection as soon as suspect strings were found) during
testing with 0 false positives.
