No third parties. No per-seat fees. Just your mail, on your server.

SMTP & IMAP

Full sending and receiving with STARTTLS, implicit TLS on ports 25, 587, 465, 143, and 993.

Web client

Clean browser-based interface for reading, composing, and managing mail. No desktop app needed.

Spam & phishing guard

Bayesian content analysis, RBL lookups, SPF/DKIM verification, and phishing detection built in.

DKIM / SPF / DMARC

Auto-generated keys and DNS records. The admin panel gives you copy-paste values for your registrar.

Admin panel

Manage users, view DNS configuration, and monitor the server from one dashboard.

Docker deploy

One docker-compose up and you're live. Works on ARM64 and x86. CI-ready.

Up and running in three steps

Deploy

Spin up the Docker stack on any Linux VPS. Nginx and Let's Encrypt handle TLS.

Configure DNS

Copy the generated MX, SPF, DKIM, and DMARC records from the admin panel into your DNS provider.
