Bayes_50 means that Bayes doesn't know if the message is ham or spam, since it
hasn't seen enough tokens yet to determine. So it would be wrong to consider a
bayes_50 (or bayes_49 or Bayes_51) to be either ham OR spam. It is an "I don't
know!" case.
This is not a case of bayes scoring too high, but if anything it is scoring too
low. "High" scores for bayes are 00 or 99, and "low" is 50.
Offhand I can't think of anything that would cause Bayes to score all messages
with bayes_50, other than a very corrupted bayes database. In fact, I'm a
little surprised that bayes_50 is even showing up. Since that is the "oh
nevermind" case I thought that (at least in 2.6x) it didn't even bother
sticking that result in the message.
