Mailcow-dockerized is an open-source email hosting platform that provides a complete, self-hosted infrastructure suite. It bundles message transfer, storage, and security protocols into a modular, containerized environment designed for deployment on private infrastructure.
The platform distinguishes itself by integrating a centralized management interface for configuring mail domains and user accounts alongside collaborative tools like shared calendars and contact lists. It includes automated security features such as integrated spam and malware filtering gateways, as well as automated certificate management to ensure encrypted communication across all hosted domains.
The system covers a broad range of administrative and operational capabilities, including automated mailbox migration from external providers and performance monitoring tools to track service health. It utilizes a reverse-proxy-based architecture to manage traffic routing and persistent storage volumes to maintain data integrity across container updates. The project is distributed as a containerized suite with configuration-driven provisioning to support consistent deployments.
