Thanks for the breakdown! Is Inbox supposed to be used for the inbox-outbox model on supported clients?
Discussion
Yes, but even more specifically as it’s only for private messages. Amethyst lets you select what relays to write a DM to, for example. If both you and your recipient had inbox and only wrote DMs there (kind 4 or giftwraps) the metadata would never leak (except to the relay operator).
Inbox also lets you delete private messages where you were the recipient (like an actual email inbox) using kind 1984 reports as well as messages you’ve authored (with traditional kind 5 events).
I have to try it then!
Have to say those specialized DM/giftwrap relays are looking more and more like SimpleX's SMP servers 🙃
Since I have it here, wen tor onion addresses for your relays? Let's get wine on this list: https://github.com/0xtrr/onion-service-nostr-relays
