About Mox

Mox is a full-featured email server that handles SMTP, IMAP, and submission protocols. It automatically provisions TLS certificates via ACME and includes a built-in DMARC reporting system. The server supports international email, Unicode username local parts, and implements the latest email standards like SMTP MTA-STS and TLS reporting.

Mox uses a message store in the maildir format and includes a webmail interface. It comes with automatic spam filtering using rspamd integration and provides a comprehensive web admin interface for managing domains, accounts, and settings. The software is designed to be easy to deploy with a single binary and minimal configuration.

Mox is developed by mjl and is licensed under the MIT license. It is written entirely in Go, making it cross-platform but primarily targeting Linux and BSD systems. The project is currently in beta, with active development focusing on stability and feature completeness.
