AngryDad writes "HexView has proposed a method to deal with spam without scanning actual message bodies. The method is based solely on traffic ****ysis. They call it STP (Source Trust Prediction). A server, like a Real-time Spam Black list, collects SMTP session source and destination addresses from participating Mail Transfer Agents (MTAs) and applies statistics to identify spam-like traffic patterns. A credibility score is returned to the MTA, so it can throttle down or drop possibly unwanted traffic. While I find it questionable, the method might be useful when combined with traditional keyword ****ysis." What do you think? Is this snake oil, or is there something to this?
