That may guarantee no false positives, but I don't think it guarantees no false negatives (i.e. don't rely on it to catch all of them). All but one of these I've seen came through mail lists (sans payload), so the Date: header wouldn't be as originally sent. But I have one that came direct and has a "normal" Date: header that is not lower case. ---------------------------------------------------------------------------- This list is provided by the SecurityFocus ARIS analyzer service.
