|Heuristics anti-spam technology analyzes patterns of content in large numbers of messages, using that information to screen out new threats. The technology is considered more flexible and effective than so-called "signature-based" anti-spam products, which identify spam messages by matching them to copies of the same messages which have already been received.
The new anti-spam feature, which Microsoft is calling the Exchange Intelligent Message Filter (IMF), uses heuristics technology developed internally at Microsoft, according to the information.
Information from Microsoft's Hotmail free Web-based e-mail service will be used to keep the Microsoft heuristics database up-to-date on the most recent spam trends.
