Modoboa
Open source email server with a web administration interface
Modoboa is an open source email server that installs and configures a complete mail system, paired with a web-based administration panel. It addresses the setup complexity of running your own mail infrastructure by bundling components into a single installer that handles most of the work, leaving DNS configuration to the user.
The platform includes built-in webmail, calendar and address book management, filtering rules, and an auto-responder, alongside unlimited domains, mailboxes, and aliases. An administration panel manages these resources, with built-in monitoring for traffic statistics and a migration tool. Communications are encrypted by default via TLS with a Let's Encrypt certificate, and SPF, DKIM, and DMARC protocols are supported for sender reputation.
Modoboa is aimed at individuals and organizations seeking to host their own email rather than rely on external providers. The core software is open source and freely available. Installation, issue-specific assistance, and annual maintenance are offered as separate paid services.
