In article <6755d0cef49e465bbf2bd170dbdc6aa3@bayviewphysicians.com> you write:

Not really. DKIM was deliberately designed not to be tied to any
visible part of the message. ADSP was a poorly designed hack that was
never implemented other than small experiments, and that I don't think
many people understood. I got a lot of grief for making the most
strict policy "discardable" even though that's obviously what it was.

R's,
