A one-click email server setup tool that turns a fresh Ubuntu machine into a fully functional mail server with webmail, DNS, and spam filtering.
About Mail-in-a-Box
Mail-in-a-Box is an open source project that automates the deployment of a complete email server on a Ubuntu system. It installs and configures Postfix, Dovecot, Roundcube, Z-Push for ActiveSync, SpamAssassin, and other components. The setup script handles DNS records, SSL certificates via Let's Encrypt, and provides a web-based control panel for managing domains, users, and aliases. Everything runs on a single machine with no external dependencies. It is designed for individuals and small organizations who want to host their own email without the complexity of manual configuration. The project is maintained by a community of contributors and uses the MIT license. Mail-in-a-Box works best on a clean Ubuntu 18.04, 20.04, or 22.04 installation and requires a domain name pointing to the server's IP address. Notable features include automatic backups, greylisting, and a firewall. It is a practical choice for anyone seeking a self-hosted email solution with minimal overhead.
