After all the blacklist checks and the server rules, the majority of the spam that gets through is simply that messages that contain nothing but an image. No text exists in the body except that which appear in the image. Rules obviously cannot filter that. Has anyone had any success blcoking these kinds of messages. If I could get rid of these, I’d be in good shape.Thanks,

Jamie,
no.Spam.domino has a rule logic which looks at the ‘invisibility ratio’ of a message… i.e the ratio of visible stuff like text in the message source to invisible stuff like images… that will sucessfully catch such messages. http://www.drcc.com/nospamdomino
