A key Internet standards body gave preliminary approval on Tuesday to a powerful technology designed to detect and block fake e-mail messages. It's called DomainKeys Identified Mail, and it promises to give Internet users the best chance so far of stanching the seemingly endless flow of fraudulent junk e-mail.
Yahoo, Cisco Systems, Sendmail and PGP Corporation are behind the push for DomainKeys, which the companies said in a joint statement will provide "businesses with heightened brand protection by providing message authentication, verification and traceability to help determine whether a message is legitimate."
The draft standard that the Internet Engineering Task Force adopted is more promising than most other anti-spam and antiphishing technologies because it harnesses the power of cryptographically secure digital signatures to thwart online miscreants.
