  Sorry... I must have missed that comment of Vernon's in the midst of
his diatribes, inventions, and ad hominem attacks.

  That question can be trivially answered by reading the RMX I-D.
Quoting from Hadmut's -00 draft:

   8.1.5.  Unforged Spam

   This proposal does not prevent Spam ...


  I think that's the crux of the confusion surrounding the opposition
to RMX: the misunderstanding of it's intent and operation.

  He continues:


   However, the RMX approach is rendered ineffective, if the sender
   doesn't forge. If the sender uses just a normal address of it's own
   domain, this is just a plain, normal e-mail, which needs to be let
   through. Since it is up to the human's taste whether this is Spam
   or not, there's no technical way to reliably identify this as Spam.
   But since the sender domain is known, this domain can be
   blacklisted or legal steps can be gone into.


  Which deals with the limitations of the proposal.
