More Tools to Combat Spam

"As reported from the New Scientist, researchers from IBM and Cornell University developed a new algorithm for detecting spam in e-mails called SMTP Path Analysis. The algorithm works by examining the path information (probably by looking at the Received headers) and detects patterns that are likely to be the route of a spammer. Though the algorithm is not meticulous enough to catch spam on its own efficiently, it works well when combined with content filtering tools. Engineers at ActivSoftware recently announced their new algorithm called "slow start outbound connection ramping." This new technology attempts to avoid becoming flagged as spam by automatically monitoring delivery success and failure rates and adjusting simultaneous connections to an e-mail service provider based upon those parameters."
