Well, you're probably going to have to re-train from scratch.

Review every message in your training corpora to ensure they are properly 

Add a bunch of new ham and, if you have any, new spam.

Very old spam (say, >5 years) may not be too useful, and probably should 
be omitted, unless you have a very small spam corpus.

Turn off autolearn. I'm in a similar situation and hand-training on the 
rare misses works great for me.

Also, given your low volume, I would recommend quarantining all spam, and 
not having a discard threshold score over which spams are thrown out 
unseen. Any that do get delivered can be reviewed and added to your 
spam training corpus.

Zap your Bayes database, re-train and see how it goes.
