The IESG has received a request from an individual participant to make

- RFC5617 from Proposed Standard to Historic
The supporting document for this request can be found here:

I support this change, for the reasons articulated in the request and in this thread.
I am the lead developer and maintainer of OpenDKIM, an open source implementation of DKIM and related standards, including VBR, ADSP, the recent REPUTE work, and some others. It is widely deployed, including use at a few of the largest operators. An informal survey was done on one of the mailing lists where this package is supported, asking which operators do ADSP queries and which act upon the results. I have so far only received a half dozen answers to this, but the consensus among them is clear: All of the respondents either do not check ADSP, or check it but do nothing with the results. One operator puts disposition of messages based on ADSP results into the hands of its users, but no statistics were offered about how many of these users have ADSP-based filtering enabled. That same operator intends to remove that capability once this status change goes into effect.
