Nothing has changed in the latest version in terms of how
SpamBayes decides what is spam and what isn't. However, if you just
retrained then you have changed the information that SpamBayes has available to
base its decisions on.
Training on "several thousand recent spam and good"
messages is not recommended. Some detailed discussions of training
strategies are available on the SpamBayes wiki:
One problem that we often see when people retrain SpamBayes
on a large number of existing messages is that they have far more spam messages
than they do good messages. This produces an imbalance that can,
particularly in extreme cases, have a significant negative effect on
accuracy.
If you could post the clues from a spam message that was
left in your Inbox (get the clues before training the message, please), that
would be extremely helpful in diagnosing your problem.

Subject: [Spambayes] Spambayes not working as well as it used to
I just upgraded
spambayes to the latest version (1.0.1) and rebuilt my spam database using
several thousand recent spam and good messages. I've continued to train
spambayes daily for several days, but I'm still getting tons of spam in my inbox
and more "spam suspects" than I used to. I think something got screwed up in the
latest version because it is not working as well for me. I used to have to sort
only 5-10 messages by hand each day, now I have dozens and dozens that get
through. Are there any known issues with the latest
build?
