I'm using sb_imapfilter.py, no sb_mboxtrain. sb_imapfilter.py does 
not have an -f switch. I removed spambayes.messageinfo.db before 
running the training database. That should do the same thing as -f, 
right?

Here are the commands I use to reproduce this:

[tony ~]$ rm hammie.db spambayes.messageinfo.db
[tony ~]$ /usr/bin/sb_imapfilter.py -t
[tony ~]$ /usr/bin/sb_imapfilter.py -c

I found something else that is interesting. When I train again, it 
trains 4 more messages, which should have been trained already. Here 
I train twice in a row and it trains 8 more messages each time:

I'll try to figure out why sp_imapfilter.py is retraining those messages.
