Maybe I didn't quite see if this is "implied" in SUBMITTER

o Suggestion to improve SUBMITTER proposal: Persistent User
Account (PUA)
[snip]
Solution:
A SUBMITTER compliant server *MUST* use the ISP user
account's persistent user address (PUA) for the SUBMITTER
address when the return path is not part of the ISP domain.
In principal, I think this is a good idea, and in fact the spec already
provides an example (5.3 - Mobile User) which illustrates how this could
be done. I will add some wording to this example to the effect that
ISPs may want to do this generally whenever the MAIL FROM is not an
account on their network.
The -02 revision actually makes SUBMITTER mandatory whenever the PRA
differs from MAIL FROM (in -01, it's a SHOULD). I think that covers
part of the requirement you've stated above. Beyond that, I do not want
to prescribe _which_ account the ISP should use in SUBMITTER. That's a
matter for ISP policy.
Thanks
