Django-based web interface for GNU Mailman 3 mailing lists

Postorius screenshot

Postorius is a Django application that provides a web-based user interface for GNU Mailman 3. It lets list owners and administrators manage mailing lists and helps users manage their subscriptions through a browser.

Key Features

  • Web-based administration of Mailman 3 mailing lists
  • User self-service for subscriptions and list preferences
  • Integrates with GNU Mailman Core via its REST API (through the Mailman client)
  • Django-based architecture suitable for deployment behind common web servers

Use Cases

  • Hosting and administering community or organizational mailing lists with a browser UI
  • Providing list members a self-service portal to manage subscription settings
  • Operating the GNU Mailman 3 “suite” alongside other components such as HyperKitty

Limitations and Considerations

  • Requires a running GNU Mailman Core (Mailman 3) instance to be functional
  • Designed primarily for Mailman 3 and not intended to manage other mailing list systems

Postorius is a core component of the Mailman 3 ecosystem, adding a practical web interface on top of Mailman Core’s list management capabilities. It is best suited for operators who want browser-based administration and member self-service for Mailman-hosted mailing lists.
