@smallcircles @silverpill @fedify that's probably an interesting discussion to have. As far as https://chatmail.at efforts are concerned, we are using SMTP in very dumbed down manner because it's all about relaying E2EE messages with no metadata. All logic is in the client, where however https://github.com/chatmail/core/blob/main/standards.md and https://github.com/chatmail/core/blob/main/spec.md come into play. Bot or client are recommended to use the "deltachat-rpc-server" which implements the spec and ietf standards, simplifying coordination.
