Mailman has a large number of site-wide configuration options which you should
now review and change according to your needs. Some of the options control
how Mailman interacts with your environment, and other options select defaults
for newly created lists5.
There are system tuning parameters and integration options.
The full set of site-wide defaults lives in the
$prefix/Mailman/Defaults.py file, however you should
never modify this file! Instead, change the mm_cfg.py file in
that same directory. You only need to add values to mm_cfg.py that are
different than the defaults in Defaults.py, and future Mailman upgrades
are guaranteed never to touch your mm_cfg.py file.
The Defaults.py file is documented extensively, so the options are not
described here. The Defaults.py and mm_cfg.py are both
Python files so valid Python syntax must be
maintained or your Mailman installation will break.
Note:
Do not change the HOME_DIR or MAILMAN_DIR variables.
These are set automatically by the configure script, and you will
break your Mailman installation by if you change these.
You should make any changes to mm_cfg.py using the account you
installed Mailman under in the 14 section.
In general, changing the list defaults
described in this section will not affect any already created lists. To make
changes after a list has been created, use the web interface or the command
line scripts, such as bin/withlist and bin/config_list.
