Bogofilter. It's fast enough to cope with the volume of spam I get
without a problem (about 2500/day at the moment), and I've had zero
false positives, zero false negatives, and I only get a handful (maybe
5 or 6) of "unsure" classifications per day. Highly recommended.

Sadly, I'm currently getting my mail via POP3 from my ISP, so the
envelope information has been lost by the time it gets to me. However,
I'm just about to start running my own MX, which will enable me to a)
make use of the envelope information, and b) reject mail early on in
the SMTP conversation.

For pretty much the ultimate spam filtering solution, see Jef Poskanzer's
mail filtering pages here:

Over a million messages a day, on a single moderate spec box over a
1.5Mb/s line. Yet another reason to be running an MTA that supports
the Milter API (which I believe is more than just sendmail these days).
