Following a hard drive crash I am rebuilding my small home server on a

One of the casualties of the HD crash was my spam corpus. I had a (very

that to sa-learn.
All my messages hit BAYES_00.
Well, you're probably going to have to re-train from scratch.
Review every message in your training corpora to ensure they are properly
classified.
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.
