     DKIM Sender Signing Practices  (draft-ietf-dkim-ssp-01)

Wow, thanks for a very thorough review.

The biggest problem with this draft is that it goes way beyond
defining a protocol.

Part of it describes the way that senders publish statements about
their sending practices and the way that receivers can look for those
statements, which is fine, but the rest attempts to tell receivers
what to do with mail they have received, which is not.

It really needs to back up and define how a sender publishes its
policy, how a recipient can look up a policy if it wants to do so,
then stop.  That's all they need to interoperate.

While senders certainly can't dictate receiver policy, giving an indication of 
what they expect to have happen is perfectly reasonable and reduces 
uncertainty.
