How does that add accountability?

I feel like it's still subject to address harvesting.

e.g.

        b...@example.com -> filtered to spam
        bob+megac...@example.com -> delivered to inbox

Unfortunately too many MegaCorps balk at the "+" in the email address. Or at least WAY TOO MANY web forms do.

If non-MegaCorp email arrives at bob+MegaCorp, the damage can be contained by filtering bob+MegaCorp and issuing a new token to MegaCorp.

You can achieve the same result with different email addresses too. This avoids the "+" character issue.

Or did you mean some sort of (loose) authentication ~> authorization by tying the from address to the receiving address?

I like this idea, and have used a form of it. But it has a weakness of MegaCorp outsourcing things to 3rd parties that send email legitimately on MegaCorp's behalf to you from an email address not associated to the receiving address.
