One of the things that doesn't impress me about SpamBayes' and
SpamAssassin's statistical filter (they use the same basic design) is that
it works on the basis of presence of words, not frequency of words. This
makes them relatively easy to fool. I don't know if DSPAM is cleverer or
not -- it isn't usable here because it doesn't work with Cyrus.
