Modoboa

Modoboa is an open source platform for hosting and managing email. It combines mail hosting and management functions in one system, with a modern, simplified web interface for accessing both. Through this interface, users can work with the platform’s core features and manage the same mail services that it hosts. The interface provides a clear way to access these functions without separating mail hosting from mail management. Modoboa is for people or organizations that want to host and manage mail services through a single web interface. It can replace Gmail as an email platform, but it is not the same kind of product. Gmail is a paid email product, while Modoboa is specifically a platform for mail hosting and management. Its stated capabilities focus on bringing those core functions together; no broader set of Gmail-equivalent features is specified.
