Your email stack, your choices.
Pick what runs on your box. Docker or bare metal. The rest configures itself.
A modern fork of Mail-in-a-Box. One command to start. No cloud dependency. No vendor lock-in. No PHP unless you want it. Works however you need it to.
Features
PHP-free by default
Rav is Rust, FileBrowser is Go, Radicale is Python. The whole non-mail stack, rebuilt without it.
Auth your way
Password, TOTP, or hardware passkeys - your choice. All supported natively, nothing extra to configure.
Flexible deployment
Docker or bare metal - your call. Isolated containers when you want them, a single machine when you don't.
Rebuilt admin panel
Built from scratch with Vue 3 and TypeScript. Dark mode, full REST API, no legacy baggage.
Auto-configured DNS
SPF, DKIM, DMARC, DNSSEC, DANE, and MTA-STS set automatically on first run. No manual zone editing.
Modern IMAP stack
Full Dovecot 2.4 support with correct plugin config, sieve scripting, and updated TLS defaults.
Deploy
Full stack. One script.
Fresh Ubuntu LTS, a domain you control, and five minutes. Everything validated before going live. Safe to re-run at any time.
