modoboa/modoboa

Modoboa is a mail hosting and management platform that provides a modern web interface for administering email services and accessing webmail, calendar, and address book functionality.

The platform solves the complexity of managing mail servers by integrating with established mail software like Postfix and Dovecot, using a SQL database as a central communication point between components. Rather than replacing these tools, Modoboa layers administration and user-facing features on top of them, allowing operators to manage domains, users, and email traffic through a unified interface. The system is built with modularity in mind, with all current features implemented as extensions that can be customized or replaced.

Modoboa suits organizations that want to self-host email infrastructure without the operational burden of managing mail servers through command-line tools. It works well for small to medium deployments where a simplified administration panel and webmail access are priorities. The platform includes reputation protection features such as DNSBL checks and DMARC reporting, per-user Sieve filters, autoreply messages, and graphical statistics about email traffic. An official installer is available to simplify initial setup, and a demo installation allows prospective users to evaluate the system before committing to deployment.

The project maintains active test coverage tracking and automated workflow checks. Development follows a modular architecture where extensions can be developed independently, and the codebase is organized to make expansion straightforward for developers wanting to add custom functionality.
