Ballot Text

Technical Summary

  DKIM deliberately makes no binding between the DNS domain of the signer of a
  message and any other identity found in the message.  Despite this, there is an
  automatic human perception that an author domain signature (one for which the
  RFC5322.From domain matches the DNS domain of the signer) is more valuable or
  trustworthy than any other.  There is currently no protocol by which an ADMD can
  announce that DKIM signatures on its mail added by other ADMDs should also be
  considered trustworthy by verifiers.  This presents an experimental mechanism
  for doing so.

Working Group Summary

  This is an individual submission, but was discussed with the former DKIM
  participants, on the DKIM mailing list.  Note that there is NOT general
  agreement that this protocol is important, or even useful.  There is good
  consensus that experimentation is needed to determine utility, and this document
  sets up that experiment by proposing a protocol for it.

Document Quality

  ATPS has been prototyped, in preparation for this experiment, and is available
  in an open-source implementation.  Other implementations are expected as
  the experiment proceeds.


  Barry Leiba is the Document Shepherd.
  Sean Turner is the responsible Area Director.


  The new registry should be nested under DKIM Parameters.
