Modoboa

Modoboa is an open-source email server that aims to democratize email hosting, allowing anyone to set up their own secure and private mail infrastructure. It addresses the limitations of both commercial email providers (cost, customization) and free services (data usage, limited features) by offering a robust, self-hosted alternative. The platform integrates various best-of-breed open-source components into a unified web interface, simplifying what is traditionally a complex setup process.

The core value proposition of Modoboa lies in its ability to provide a full-featured email server with minimal effort, thanks to its automated installer. Users gain complete control over their data, choosing where it's stored and how it's managed. Beyond basic email, it includes features like webmail, calendar and address book management, filtering rules, and auto-responders. Security is a priority, with default TLS encryption and support for critical email authentication protocols like SPF, DKIM, and DMARC to protect against spoofing and enhance deliverability. Modoboa fosters a community around its project while also offering professional services for those who require expert assistance with installation, troubleshooting, or maintenance.
