An image is just content - much like text or HTML. How useful DCC/RAZOR/etc. would be depends highly on how they are used and on how sophisticated the spammer is. What I suggested is not the end-it-all solution for spam detection but another tool to add to the spamassassin toolbox. Also, generating new images potentially is computationally expensive enough that most spammers wouldn't try it. Over 50% of my false negatives this week would have been properly identified by IDing the image. YMMV. Tim
