Bill Nussey writes on CircleID: [snip] At The Email Authentication Implementation Summit in New York City last week, several major ISPs surprised attendees with their announcement that they are jointly backing a single authentication standard. Yahoo!, Cisco, EarthLink, AOL, and Microsoft got together and announced they are submitting a new authentication solution, DomainKeys Identified Mail to the Internet Engineering Task Force for approval as a standard. This is big news. To date, these groups have been at odds over authentication, with each promoting their own authentication techniques. While it is likely that each will continue to support its own standard for now (Microsoft with Sender ID, AOL with SPF and Yahoo! with the original DomainKeys), we can expect that they all will begin to use this common standard over the coming years if it is adopted by the IETF.
