Mail::SpamAssassin::Plugin::Bayes - determine spammishness using a Bayesian classifier

DESCRIPTION

This is a Bayesian-style probabilistic classifier, using an algorithm based on the one detailed in Paul Graham's A Plan For Spam paper at:

  http://www.paulgraham.com/spam.html

It also incorporates some other aspects taken from Graham Robinson's webpage on the subject at:

And the chi-square probability combiner as described here:

The results are incorporated into SpamAssassin as the BAYES_* rules.
