mailroom

Self-hosted email for the masses

Mailroom is an email server designed for simplicity and quick setup. It's still a work in progress, but I intend to see it to production readiness.

Mailroom is written in Rust, using tokio as the async backend and sea-orm as the orm.

Why?

I began working on mailroom because I wanted to learn how email works. No amount of reading can replace learning by doing.

Design Philosophy

The #1 design goal for mailroom is to be extremely simple to set up and administrate. Going from registering a domain to hosting your own email server should take less than 20 minutes.

In scope features:

• Automatic TLS certificate management. The user should never need to worry about acquiring or renewing certificates unless they opt into more advanced configuration options. Additionally, TLS must be enabled by default.
• Simple configuration. Defaults should be sensible and work out of the box. No configuration changes required to get a fully functioning email server.

Out of scope features: (may come into scope as the project matures)

• Web administration interface. Designing a web-based interface for administrating mailroom would increase complexity and project scope beyond what I want to undertake.
• Email client. Mailroom is only an email server, not a client. To read and send emails through mailroom, users must use a separate email client such as Thunderbird.
