Perhaps, but a stable base for future enhancements that will actually have some utility is not, I would think, something useful. Unless the output of this putative group would at least enable a receiver to reject a 'bad' message or have more confidence in a 'good' message there is no incentive for either senders or receivers to deploy. It would seem to me that there is a necessary tie between the identity being signed, some e-mail identity that end uses actually see, and some type of sender policy declaration that would allow receivers to have some idea how to interpret the presence, absence, and validity of signatures. Unless we can get to at least that, then I don't think we've accomplished anything useful. Scott Kitterman _______________________________________________ ietf-dkim mailing list <http://dkim.org>
