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

SYNOPSIS
DESCRIPTION
    This is a Bayesian-like form of probability-analysis classification,
    using an algorithm based on the one detailed in Paul Graham's *A Plan
    For Spam* paper at:

      http://www.paulgraham.com/

    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.
