Indeed. We gave this issue at least two clear consensus calls, and it's very clear that the rough consensus considers the kind of validation that Doug is asking for to be a good idea, but outside the scope of the DKIM protocol. That is, the validation ought to be done in another part of the software system. The document does actually advise that, and that advice is all that working group consensus was behind. Consensus also is that Doug is severely overstating the problem. This has been decided and re-decided. > And I find the tactic of taking a lost battle from a working group to the > IETF as > a whole to be akin to the "Mom said no, I'll go ask Dad!" strategy that I > outgrew > by the time I was a teenager... I, too, have a problem with how IETF last call is sometimes being used by working group participants to rehash issues. But that's a subject for a separate conversation, and not for here.
