Can we implement nostr-based email?
Discussion
it would essentially act as email but I dont see the reason for reproducing it exactly. At least allowing opt in email integration you're reaching the outside world (outside of nostr)
Nostr DMs practically are email. They should expire on the server though.
Expiry dates on events would be a great thing for assisting in managing the volume of data to eliminate stuff that users don't need to have relayed any more.
Maybe relays can advertise their expiry timeframes or is that controlled elsewhere?
I already thought a lot about this while designing a gossip protocol for Indra. Not having expiry for ephemeral data makes managing the purging of caches complicated, much simpler to put a reasonable time window on it.
As far as this nostr protocol goes, quite frankly, it's amateur hour in protocol design, and the supposed designer of it amply demonstrates on a regular basis how little he understands about security, distributed systems or even the most basic things like why bitcoin doesn't benefit from being anchored to shitcoin chains.
