Show HN: mnm, an open source project to replace email and SMTP

The mnm project is building a legitimate* replacement for email: a client, a server, and a simple protocol between them.

The project is seeking contributors and patrons. It has been in progress since 2017, wholly self-funded. This is the first announcement to a wide audience.

[*] Legitimate, meaning decentralized, store-and-forward, open protocol, open source.
