Postorius
A modern Django-based web UI for managing Mailman 3 mailing lists with REST API integration.
About Postorius
Postorius is the official web interface for Mailman 3, the open source mailing list manager. It replaces the older Pipermail and Mailman 2 admin interfaces with a clean, modern Django frontend. You can create and manage mailing lists, moderate messages, handle bounce processing, and configure subscription policies all from a browser.
The tool integrates directly with Mailman 3's REST API and HyperKitty, the archiver. It supports Django authentication backends, LDAP, and OAuth, making it easy to plug into existing user directories. Postorius runs on any platform that supports Python and Django, typically deployed alongside Mailman 3 core, a database, and an archiver on Linux servers.
It is open source under the GPLv3 license, maintained by the Mailman project through the Free Software Foundation. Ideal for organizations that want self-hosted mailing list management without proprietary dependencies. Postorius is the recommended admin panel for all new Mailman 3 installations.
