If you have a beast for filtering, there is 2 options:
* FuzzyOCR
http://users.own-hero.net/~decoder/fuzzyocr/
Basically, it OCR's the image and then spamassassin can use the content
to filter (based on presence of STOCK, TICKER ....
* ImageInfo
http://www.rulesemporium.com/plugins.htm
ImageInfo is based on number and size of images in the message.
ImageInfo will (may) be included in the next release of spamassassin.
I didn't tried it though, I dont have the ressouces to do that on a
gateway transiting 10.000+ messages a day.
