I don't know if this will help, but we have a fairly well-trained 
spamassassin token database that we use on our mail server. We train it 
with all our spam, and occasionally we download the content of our gmail 
spam boxes and train it with that as well. It catches about 90% of our 
spam. Not sure how you'd use it with spambayes though, I don't know 
spambayes at all.

I could also make available the content of our spam mailboxes if you'd 
like to train your spam checker with that?

It all depends whether your spam is the same as ours I suppose. At the 
moment we get about 700 of these fake newsletter things per day.
