Cloudmark combating spam

Cloudmark added a new feature to its Cloudmark Authority 2.0 security tool to help Internet service providers reduce spam. <A HREF="http://www.eweek.com/article2/0,1895,2086717,00.asp?kc=EWINFEMNL012407EOAD">Cloudmark's Active Scan</A> is able to block the vast majority of unwanted email by allowing service providers to filter unread messages against up-to-the-minute lists of known attacks. Every minute, Authority 2.0 updates local caches of message fingerprints, allowing a simple but sophisticated rescan to be performed locally by checking header information against these caches.
