Differences in the counts can also be caused by manual training.  13126 is
the number of spams *trained* while 7131 is the number of spams *processed*
by SpamBayes, so they're counting different things.  If you've ever used the
"Train on a message, mbox file or dbx file" option to train on additional
spam messages, those messages will be included in the trained count but not
in the processed count.
