I am using it as well since some days. Works quite amazing, even with the 
provided short but reasonable wordlist.

One fine thing also is, that you can tune it not to scan mails which already 
got a spamassassin score over a certain treshold. So you won't have to do an 
OCR on mails with images spamassassin already marked as spam :-)
