Anti-Spam System Approved

The Internet Engineering Task Force has approved a new tool to fight spam.
Called DomainKeys Identified Mail (DKIM) uses encrypted digital signatures to prove a message's origin.

Because it incorporates a digital signature, "it allows a piece of e-mail to be identified definitively as somebody's rather than as an e-mail coming from an IP address that could used by multiple people or a spam bot," according to Dave Crocker, an IT consultant and contributor to the DKIM project.
