SMTP requires that those fields be world-readable. Or do you propose that SMTP servers somehow route email to the appropriate recipient without being able to read who the recipient is?!
No, what I propose is that we start using a protocol other than SMTP for email. I don't think such a protocol exists yet, and I don't know much about how it would look, but I think AC #49126801, right above, has some good ideas.
