Another anti-spoof RFC proposal
http://serverauthority.net/draft-lorenzen-marid-mxout-00.txt
BTW I'm not that keen on it at first sight, but need more time to

Seems most, if not all of it is covered by SPF, though it requires

Also getting admins to configure mail servers to existing RFC's is
bad enough.
