What would it take to remove DNS from the mix with ethmail addresses, and replace with ENS?
I guess it would take some substantial work to rebuild SMTP / POP / IMAP to use ENS, and might require a green-field mail routing network (or would it?), but one which could be bootstrapped with the right incentives…
But I think it would be cool to make progress towards a world where I can send emails to firstname.lastname@example.org
Or are we still too early for this? What do you think?
