[Spambayes] lots of unsures, heavily biased towards spam

[David Abrahams]

I'm getting what the title says.  I very rarely see ham classified as
unsure, and I get a few hundred unsures per day.  I keep training on
the unsures, which means my database accumulates lots more spam than
ham over time.  Is there anything I can do to help reduce the number
of messages classified as unsure without hurting Spambayes' ability to
correctly recognize ham?

Thanks,
