Everyone.net, an e-mail provider, has released its Total Protection 2.0, an e-mail protection service with an encryption technology that stamps a unique signature for every message that is sent out. It focuses on bounce 'storms,' an event in which e-mail users who have had their e-mail addresses stolen by e-mail worms or spammers receive a huge amount of returned spam messages. Total Protection uses Email Fingerprint technology. This technology ascribes an extension header, which is created with a symmetric encryption key and uses information such as the e-mail user's identification, the time stamp of the e-mail, and so on, to each e-mail message that is sent out. When the external e-mail servers return the header, it now includes a new fingerprint extension and usually a portion of the original e-mail. This setup lets Everyone.net search bounced messages for the unique signatures to see if the messages came from an Everyone.net user. It detects bogus bounce messages that were sent by spammers. This service keeps Everyone.net customers from being overwhelmed with rejection notifications for e-mail messages that were never sent.
