DeltaChat has just made its long-awaited Wireguard-esque multi-relay release.

You can add multiple relays (chatmail/email accounts) to your profile. Your account now survives server outages, censorship, or even government seizures. Your identity is not tied to a single email address anymore.

Change to another relay, message your contacts/groups, and they'll immediately learn the new address they can reach you at and will respond using that address now.

Just like how Wireguard gets a valid encrypted packet from a peer at a new IP address and automatically starts using it.
