So a key fingerprint? >Hopefully there would be forward secrecy this time. I for one would not want to delete all my email on receipt. Otherwise there is no point, the attacker gets the stored email when they get the private key if the email is still available to the user. Normally people keep their email indefinitely. I hope this is not a proposal to store email insecurely. Having said that, I have sometimes thought that it might be cool and maybe even useful to have a "Mission Impossible" style email type that would entirely delete itself after reading. I think this part of the proposal needs much work. A good first step would be to study the details of current encrypted email technical culture.
