With SpamAssassin 2.6x and Bayesian autolearning enabled (the default, I
think), we're way below 5% false positives and false negatives, both for
each individual recipient and organization-wide (~50 recipients).  That's
with zero manual Bayesian training.  From what I've heard, our results
aren't unique or hard to reproduce.  YMMV..
