OT: Comparisons of different Bayes Engines, etc.

[Forrest Aldrich]

I'm looking for comparisons and/or reviews of the various Bayes-specific
anti-spam engines -- Spamassassin, Bogofilter, etc.  Gathering features,
performance, ability to tune, actual application in the real world
(commercial), etc.

Specifically, their application in the enterprise.

If anyone knows of such resources or has performed these, I would
appreciate hearing.


Thanks.
