IETF questions SenderID

Published on .

Microsoft Corp.’s SenderID authentication protocol suffered a setback when the Internet Engineering Task Force, a group of technologists, indicated concern about adopting a standard backed by the dominant software marketer, which holds patents for the authentication technology. Last week, America Online, which had been in the process of implementing SenderID, said it had withdrawn its earlier support of the protocol because of the IETF’s concerns. AOL said it will continue to employ the Sender Policy Framework protocol. SenderID was the moniker adopted for a combined anti-spam authentication proposal with Microsoft’s solution and Sender Policy Framework, another authentication protocol promoted as an open source solution.
