It's forgotten what spam looks like!

Hi,
I’ve only recently started using SpamSieve, and everything was going great. But now it seems to have forgotten how to spot even basic spam. The statistics are below, and although it looks like it’s doing everything right. The number of false positives seems wrong. I’ve marked dozens of spam messages to be trained as spam. But it’s missing things like mail that comes in with SPAM* in the subject line, email in Chinese, offers of meds, and other very obvious spam that I’m sure it was dealing with just fine until recently.

It is finding some spam, but it’s hit rate has decreased considerably.

Any ideas?

The false positives are the good messages in the Spam mailbox. Messages in the inbox that you train as spam are false negatives.
