A professional, production-grade SMTP server! No it's not. This demo project implements a very simple temporary e-mail, capable of receiving e-mails and storing them in libSQL (locally), sqld, or Turso.

Tutorial: Write your own email server in Rust

Example deployment: https://sorry.idont.date/

In order to get it to work, run it on a machine with public IP, port 25 exposed, and add all appropriate DNS entries - an MX entry and its corresponding A entry that points to the IP address where edgemail is deployed.

If you start edgemail with --api-port <port>, it also serves a JSON API on that port.

• GET /inbox?inbox=<email@domain>&page=<n> returns { mail, has_more_pages }, where mail contains up to 10 messages with date, recipients, sender, subject, and id; page defaults to 1
• GET /inbox/<id> returns a single message with id, date, recipients, sender, subject, and body
• after 100 API requests have been served, later requests return 503 Service Unavailable
• API requests time out after 30 seconds and return 504 Gateway Timeout

edgemail has a client you can run as a static webpage. Find all the files in client/ directory. The only thing that needs to be changed is the database URL and the readonly_token used to authenticate for read-only access.
