Cloudmark taps p-to-p to fight spam

Cloudmark has introduced SpamNet, a Microsoft Outlook add-in tool designed to block spam from reaching users' e-mail inboxes.

SpamNet uses a peer-to-peer architecture. Instead of deleting e-mail messages, SpamNet moves unwanted e-mail to a spam folder. Every time a user uses the one-click block feature to remove spam from their inbox, they also notify the SpamNet community at large. The notification then automatically blocks spam for all other SpamNet community members. Company officials claim the product can stop 75% of spam automatically.

Cloudmark does not share files, unlike p-to-p based file sharing systems such as Napster.

"The add-in runs inside Outlook so there is absolutely no file access whatsoever," Jacob said.

In addition, SpamNet provides unique identifiers for each message it receives from users.

Although this product launch targets consumers, the company plans to launch an enterprise solution in the next two to three months. The beta version of SpamNet is available now, free of charge from the Cloudmark Web site.
