Some of the options control how Mailman interacts with your environment, and other options select defaults for newly created lists<a name="tex2html5" href="#foot746"><sup>5</sup></a>. There are system tuning parameters and integration options. <p> The full set of site-wide defaults lives in the <span class="file"><var>$prefix</var>/Mailman/Defaults.py</span> file, however you should <strong>never</strong> modify this file! Instead, change the <span class="file">mm_cfg.py</span> file in that same directory. You only need to add values to <span class="file">mm_cfg.py</span> that are different than the defaults in <span class="file">Defaults.py</span>, and future Mailman upgrades are guaranteed never to touch your <span class="file">mm_cfg.py</span> file. <p> The <span class="file">Defaults.py</span> file is documented extensively, so the options are not described here. The <span class="file">Defaults.py</span> and <span class="file">mm_cfg.py</span> are both <a class="ulink" href="http://www.python.org" >Python</a> files so valid Python syntax must be maintained or your Mailman installation will break. <p> <div class="note"><b class="label">Note:</b> Do <strong>not</strong> change the <var>HOME_DIR</var> or <var>MAILMAN_DIR</var> variables. These are set automatically by the <b class="program">configure</b> script, and you will break your Mailman installation by if you change these. </div> <p> You should make any changes to <span class="file">mm_cfg.py</span> using the account you installed Mailman under in the <a href="troubleshooting.html#building">14</a> section. <p> <br><hr><h4>Footnotes</h4> <dl> <dt><a name="foot746">... lists</a><A href="customizing.html#tex2html5"><sup>5</sup></a></dt> <dd>In general, changing the list defaults described in this section will not affect any already created lists.
