Mailman - The GNU Mailing List Management System

Copyright (C) 1998-2017 by the Free Software Foundation, Inc.

This is GNU Mailman, a mailing list management system distributed under the terms of the GNU General Public License (GPL) version 3 or later. The name of this software is spelled “Mailman” with a leading capital ‘M’ but with a lower case second ‘m’. Any other spelling is incorrect.

Technically speaking, you are reading the documentation for Mailman Core. The full Mailman 3 suite includes a web user interface called Postorius, a web archiver called HyperKitty, and a few other components. If you’re looking for instructions on installing the full suite, read that documentation.

Mailman is written in Python which is available for all platforms that Mailman is supported on, including GNU/Linux and most other Unix-like operating systems (e.g. Solaris, *BSD, MacOSX, etc.). Mailman is not supported on Windows, although web and mail clients on any platform should be able to interact with Mailman just fine.
