6 Set up your mail server
</h1>
<p>
This section describes some of the things you need to do to connect Mailman's
email interface to your mail server. The instructions here are different for
each mail server; if your mail server is not described in the following
subsections, try to generalize from the existing documentation, and consider
contributing documentation updates to the Mailman developers.
<p>
<div class="Note"><b class="label"></b>
Under rare circumstances or due to mis-configuration, mail to the owner(s) of
the 'mailman' site-list (see section <a href="site-list.html#site-list">8</a>) can bounce. In order to
prevent a mail loop this mail is sent with envelope from mailman-loop which
is normally aliased as
<p>
<div class="verbatim"><pre>
mailman-loop: $varprefix/data/owner-bounces.mbox
</pre></div>
but which can be aliased to any, always deliverable, local address or file.
If you are using the Postfix MTA integrated as described in section
<a href="postfix-integration.html#postfix-integration">6.1</a>, this alias will be generated automatically. In
all other cases, you should install this alias along with your normal system
aliases.
