We really need a "Trust on First Use"(TOFU) system for messaging, that can be verifified, or pre-trusted offline, face to face. It'd be awfully nice for your bank to give you some thing that you can later verify that any communication from them (web site, online banking, text message, email, etc) are legit and verified.

Or if we can't trust users to handle TOFU, then some token/unique address/whatever that we can exchange face to face to enable trusted communication.
