NAME
    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:

      http://radio.weblogs.com/0101454/stories/2002/09/16/spamDetection.html

    And the chi-square probability combiner as described here:

      http://www.linuxjournal.com/print.php?sid=6467

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