Apparently our users use email quite a bit to share pictures. These emails typically contain no subject and no body, just the image. This hits all sorts of rules (perhaps correctly), and was just looking for input on how it should be handled. There are a few rules that seem to overlap in these instances: * 2.3 EMPTY_MESSAGE Message appears to have no textual parts and no * Subject: text * 1.8 MISSING_SUBJECT Missing Subject: header * 1.0 FSL_EMPTY_BODY Message has completely empty body Those three are enough to qualify the email as spam alone, pending any points deducted for bayes
educate your users, otherwise spammers pretty fast would switch to put their complete payload into a large image with a link on it - it happens already and hence the rules exists
but if you open that door spammers would say "thank you"
