npub...@nostr.mail ?

I mean technically speaking, if we could find a way to:

- Have a dumb SMTP server listen on p25

- that sends each email to a script,

- the script figures out who this went to (npub),

- converts it into a DM, assigns it an nsec ("address book"),

- and sends it to the related npub.

... insert clamav or other antispam stuff in there, for good meassure. Buut probably possible. I faintly remember seing an SMTP server hostable as a library in NodeJS that can technically do that.
