Internet Engineering Task Force approves the DomainKeys Identified Mail standard as a proposed standard. DKIM allows email senders to “sign” each email to verify that it comes from their domain. If the receiving domain handles an email that does not contain the signature, it can raise a red flag to warn the recipient that the message might be a fake. The new standard won’t stop spam, but if it is widely adopted it could force spammers to stop sending messages from bogus email domains. Yahoo! and Cisco say they have already deployed DKIM to help protect messages sent from their own domains.”]
