If you ask for my email, you also get my npub "@uid.ovh "

I enabled DNSec for both domains. About the emails that were never reaching the inbox, I fixed it today. Github was connecting to the bridge but my bridge was refusing the email because the from address was too long (above 64 characters before the "@"). Typically, the issue occurred when using the base36 hex or npub format as your address.

Nice spec from https://openspecs.uid.ovh/spec//image-proxy-list

I created it because no others relays care about DM privacy. I updated NIP 59 yesterday to fix a privacy issue. And implemented the updated spec today inside the relay. https://openspecs.uid.ovh/spec//nip-59

Not at the protocol level. I see 2 solutions: Remote signer, run a bunker on your key and give the other npub a connection scoped to nip44_decrypt only. They read your mail, they never hold your nsec, and you can revoke the connection any time. Closest thing to real read delegation today. Auto-forward. Your client or a script decrypts and re-wraps incoming mail to their npub. Works with any client on their side, but the copy is signed by you, so the original sender proof is lost.

No I didn't know.
