Anti-spam reaches standard status
The Internet Engineering Task Force (IETF) has granted preliminary approval to the DomainKeys Identified Mail (DKIM).
The industry standard promises to curb spam email by preventing spammers spoofing, the practice of forging the sender's email address to make it appear like the message originated from a reputable company instead of some shady offshore spammer.
DomainKeys attaches an encrypted digital signature unique to the sender to each e-mail message when it is sent. A message where the sender's address doesn't match the signature can be discarded as spam.
