Sender authentication moving ahead

A lot of things happened this week: MAAWG meeting took place, Yahoo submitted DomainKeys to the IETF and a Microsoft submitted Caller ID draft to the IETF and SPF is merging with Caller ID via an addition of an ESMTP parameter for MAIL FROM. Architechurally speaking, I liked the idea of using ESMTP for a long time, so it looks like they are moving in the right direction (to me at least). Of course the question of what you do once authentication is used will rear its ugly head very soon, which is where reputation and trust questions will need to be addressed.

At this point, I finally feel that I personally made a difference by helping with all of these various proposals in the ASRG, and the IRTF/IETF transfer process. With CID and DomainKeys finally published, SPF and CID participating in the IETF, and the ASRG’s reputation somewhat gotten better than it was when I joined, I feel a certain sense of accomplishment about my work in the ASRG. I am hoping that my small contributions made a difference in the long term future of the Internet, and will somewhat help reduce the overall spam problem.
