There are inconsistencies throughout this documentation in examples which invoke the Django management commands. The actual invocation depends on how Django and Mailman 3 are installed. It may be

  • mailman-web …
  • python …
  • django-admin …

or something else. When reading these docs, you may need to translate one of the above into what works in your installation.
