As both you and John L point out, this is a big issue. That's why I was
thinking about it being something in DNS related to the policy record so
that it would be at least slightly harder to lie about it. It's also why
I started with IF... I recognized that if it can be trivially spoofed,
then there's no reason to do it.
We can accomplish that much without any changes to SMTP:
- SMTP conversation happens as per usual
- receiver looks up MAIL FROM domain, checks SSP
- receiver decides whether to accept the message and check the
signature, or reject based on non-DKIM-related criteria
Or am I missing something?
That's the lines I'd been thinking along.
