It might be time to retrain from scratch, for a couple reasons I can think
of:

    * your training database has some mistakes in it

    * as spam evolves, your old training database reflects current trends
      less accurately.

If you have your ham and spam training databases arranged by date, perhaps
you can just lop off the oldest 20% or so of your messages, train on a
handful of the new-style spam and be on your merry way.
