About Postorius
Postorius is the Django-based web user interface for GNU Mailman 3, the long-running free mailing list manager. It gives list owners, moderators, and subscribers a browser interface for managing lists, memberships, and settings instead of working only through email commands or the shell. Postorius is free software from the Free Software Foundation and deploys alongside a running Mailman 3 installation.
