What can DCC do for image spam?

Just use DCC as a part of SpamAssassin, with Razor, Pyzor and FuzzyOCR.

Heck, throw postgrey and blacklists in postfix with it! 

I've had this exact setup since january, and most of it since june 2004. Since postgrey and FuzzyOCR were installed, spam getting in dropped by about 90%, and spam getting through is less than 1/10000.

Good luck :)

Objet : What can DCC do for image spam?

I've been reading Ironport's advertizing.  They claim good success
rates on blocking image spam.  In addition to analysis of the message
body, they use OCR techniques to extract the text from the image, as
well as examining the composition of the image for features typical of
current spam.  Could DCC do anything of this sort for image attachments?
