Stochastic informatics spam filter

The procmail script that uses stochastic informatics,
(information-theoretic stuff,) to reduce the amount of spam e-mail
users receive has its own web page now:


you will find that it uses the same concepts as tsinvest; the way the
procmail script reduces the chance of a false positive in spam
detection is identical to the way tsinvest allocates resources.

Interestingly, the probability that a message is spam isn't even
used-its the evaluation of risk that makes it work.


BTW, correctly set up and maintained, its about 2 sigma, (about 98%,)
effective, too-with virtually no chance of a false positive.
