Postorius
Django-based web interface for GNU Mailman 3 mailing lists

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.
