CircleID: News from the E-mail Authentication Summit in NYC
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.

How do you say "that was an email authentication for dummies" session without actually saying so? Here's how (my followup on circleid) By Suresh Ramasubramanian | Posted on Jul 21, 2005 @ 7:08 PM PST In the interests of setting several records straight, and making a few points clearer. "AOL's spf" is just plain wrong. SPF is by meng weng wong of pobox.com (http://spf.pobox.com). The most that AOL has done is to use it in a way that is way out of spec for what it is designed for .. tells large sites who ask it for a whitelist to consider publishing spf records, to automate the updation / maintenance of their whitelist (so if they add or remove netblocks for their sending of email, the changes can be picked up from the spf record). Even that is not necessary - all people have to do if they dont want spf is to open a ticket with aol's postmaster staff if they want their whitelist updated. Domainkeys and Cisco's IIM merged as they were fairly similar and reasonably complementary proposals - with the added advantage that the considerable experience that Cisco distinguished engineers like Jim Fenton (the author of IIM) has with IETF operations is brought to bear in polishing the joint spec. A balanced set of use cases of spf and sender id, that also documents the potential gotchas and pitfalls that exist (and show themselves quite often particularly when people publish restrictive -all spf records, and even more when sites treat spf failures as a blanket reason to immediately reject email) - http://www.maawg.org/about/whitepapers/spf_sendID/ More on the blind use of spf here - something I wrote a few months back on circleid. http://www.circleid.com/article/1039_0_1_0_C/ The email authentication summit did not go beyond fairly general issues, and can be treated as a general introduction / update to the authentication issue for people who have not been following it very closely. You may want to attend MAAWG and IETF meetings - that is where you will see a clearer picture.
