Know of https://github.com/nogringo/nostr-relay Specifically built by for the specific purpose of mails, he also wrote the NIP for mails.

Yep that's kind of the point! It works if you want it to, simply by removing other relays and adding your own! And it reuses your own DM relays, so you can set them from any nip-17 compatible app.

Emails are gift wrapped., non read protected relays will leak the fact that you got an email around the "2-day window", luckily you can set both, we are going to have our own read protected relay dedicated for this up soon as well.

MAILSTR PRIVACY UPDATE: When we released mailstr the most consistent feedback we got was, that people did not like that the mails were transparent during transit . WE TOOK IT TO HEART! We've been working non-stop to make sure this doesn't happen anymore and incorporated the solution for interoperable email encryption: WKD ! so now your mails are encrypted by default whenever communicating with a WKD supported provider eg: proton mail! For non-WKD providers (Gmail boo!) we are working on adding password encryption, which will be released soon! Also not to mention, we also fixed a lot of UI and reliability bugs you've been reporting! CHANGELOG FOR OUR LATEST UPDATE: Changelog — since v0.1.0 New - End-to-end encrypted email (OpenPGP). Compose encrypted, signed mail and read it back with verified signatures. Your private key syncs encrypted with your account and never touches a server in clear. - Automatic key discovery. The app finds recipients' public keys for you — via WKD (a recipient's own mail domain) and keys.openpgp.org — so encryption works without manual key exchanges. - Per-alias keys. Each address gets its own keypair, so your aliases stay unlinkable in public. Encryption settings. Generate or import keys per address, manage your contacts' public keys, see fingerprints. - Export and rotate! — generate or import a key per alias, download the private key as a standard .asc file (as-is or re-wrapped with a new passphrase), and republish your public key to WKD on demand. - Composer now shows encryption at a glance — a green lock when the message is encrypted, red when it isn't. Tapping a red lock explains why and links to setup. - Mail is encrypted by default whenever it's possible. - Full-screen composer on mobile — no more cramped bottom sheet. Fixed - Dark-mode emails render correctly — HTML mail authored for a white page no longer disappears. - Messages that arrived blank now show their content (with a fallback so nothing is silently lost). Maintenance - Bridge watchdog reliability, hooks-order crash, Zapstore config, sidebar icon, and assorted internal cleanup.

Not yet, and it would not be so straightforward since things are giftwrap to your pubkey, an easier option could be to give you an option to move your alias to another npub, do you think thatwould solve your usecase?

Agreed but thats not the problem statement we've given ourselves , totally different priority set for us.

wnet through it, it's a very interesting, but out of band protocol, not sure if it's on our roadmap anytime soon, would recommend using a bunker login if you want a segregated storage for your keys, but i understand that it would not be cold storage, like the client offers. Key delegation is a very evolving space and we would want to wait until implementations mature before we chose a path to build on..

Hello, , there were some reliability issues with outbound emails on mailstr, our bridge was losing connections to the relays and hence was sometimes not receiving outgoing mail. Have since fixed this, Outbound mail delivery should now be good. We are working on more resiliency efforts to make sure mailstr.app works for you reliably always. Apologies for any inconvenience, keep being awesome!
