mailman-bundler | Install GNU Mailman with Postorius and HyperKitty

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. Mailman requires at least Python 3.4, which may or may not be shipped by your operating system. If only earlier versions of Python are available, you must install Python 3.4 (or later) before following this tutorial. To do that, follow the procedure in the `Python documentation`_. You must also have Pip for Python 3.4 installed. If you’re using your distribution’s package manager, it probably comes in a python3-pip package (or python3.4-pip, or something similar). Otherwise you’ll have to `download it from PyPI <http://pypi.python.org/pypi/pip>`_. Even if Mailman 3 runs on Python 3, the web interfaces and the commands in this procedure run on Python 2.7, so make sure your system Python version is 2.7. To use Mailman, you must install and configure a Mail Transfer Agent (MTA) supported by Mailman. To this day, `Postfix`_ and `Exim`_ are supported. Installing and configuring an MTA is beyond the scope of this documentation; for assistance please refer to your specific operating system and preferred MTA. This package only provides Mailman configuration examples for Postfix. For a production setup, you first need to change the deployment parameter to production in buildout.cfg and run buildout again. It will regenerate the scripts in bin and the contents of the deployment directory. In the bundler directory, open the mailman_web/production.py file, look for the SECRET_KEY parameter and set something random. If you want to use a webserver module to serve Postorius and HyperKitty (like Apache’s mod_wsgi), make sure your current directory is accessible by its user. On some distributions, user directories in /home are not accessible by the Apache user.

the STATIC_ROOT variable, pointing to a directory where static files will be collected to be served directly by your frontend webserver, must be owned by your current user
the HAYSTACK_CONNECTIONS.default.PATH variable, pointing to a directory where the fulltext search engine files will be stored, must be readable and writable by your webserver user.
