- The draft does not mention alias-style forwarding done by an MTA;
  perhaps it could?  A 1-1 alias would seems to be easily covered,
  but 1-to-many (mail-exploder) aliases may need more thought.

- I assume that mailing-list forwarding is not intended to be covered.
  Perhaps that should be explicit.
