Yes. I had previously suggested (though I'm sure it's not a new idea) that
the user can "register" any other addresses (or entire domains) by
receiving a challenge message and clicking the link, or replying (similar
to joining a mailing list.) A challenge message to "postmaster" might
serve to authorize the whole domain.
That's still not incompatible with the sender_agents way of showing
permissions in extra bits of the output.
A user at an ISP could work through the ISP to convince them that he had
permission to send mail as otheruser(_at_)example(_dot_)com(_dot_)
Alternatively,
example.com could publish records saying that user(_at_)ISP could send as
otheruser(_at_)example(_dot_)com(_dot_)
I don't think the two methods are in conflict with one another, so we
could push for both and see which works better. :-)
