After reading this bit I had though about maybe using ocr when these types of messages are
A (not-so) quick experiment using netpbm and gocr on a linux machine here produces some
ASCII output from one of these gif images.
The question is: how can I get MailScanner / SpamAssassin to use this method?
The command line I am using is:
giftopnm test.gif | gocr -
which then produces the text on stdout.
