It has been tested with various Postfix versions up to and including Postfix 2.1.5. <p> In order to support Mailman's optional VERP delivery, you will want to disable <code>luser_relay</code> (the default) and you will want to set <code>recipient_delimiter</code> for extended address semantics. You should comment out any <code>luser_relay</code> value in your <span class="file">main.cf</span> and just go with the defaults. Also, add this to your <span class="file">main.cf</span> file: <p> <div class="verbatim"><pre> recipient_delimiter = + </pre></div> <p> Using "<tt class="samp">+</tt>" as the delimiter works well with the default values for <var>VERP_FORMAT</var> and <var>VERP_REGEXP</var> in <span class="file">Defaults.py</span>. <p> When attempting to deliver a message to a non-existent local address, Postfix may return a 450 error code. Since this is a transient error code, Mailman will continue to attempt to deliver the message for <var>DELIVERY_RETRY_PERIOD</var> - 5 days by default. You might want to set Postfix up so that it returns permanent error codes for non-existent local users by adding the following to your <span class="file">main.cf</span> file: <p> <div class="verbatim"><pre> unknown_local_recipient_reject_code = 550 </pre></div> <p> Finally, if you are using Postfix-style virtual domains, read the section on virtual domain support below. <p> <p><br /></p><hr class='online-navigation' /> <div class='online-navigation'> <!--Table of Child-Links--> <a name="CHILD_LINKS"><strong>Subsections</strong></a> <ul class="ChildLinks"> <li><a href="node13.html">6.1.1 Integrating Postfix and Mailman</a> <li><a href="postfix-virtual.html">6.1.2 Virtual domains</a> <li><a href="node15.html">6.1.3 An alternative approach</a> </ul> <!--End of Table of Child-Links--> </div> <div class="navigation"> <div class='online-navigation'> <p></p><hr /> <table align="center" width="100%" cellpadding="0" cellspacing="2"> <tr> <td class='online-navigation'><a rel="prev" title="6 set up your" href="mail-server.html"><img src='previous.png' border='0' height='32' alt='Previous Page' width='32' /></a></td> <td class='online-navigation'><a rel="parent" title="6 set up your" href="mail-server.html"><img src='up.png' border='0' height='32' alt='Up one Level' width='32' /></a></td> <td class='online-navigation'><a rel="next" title="6.1.1 integrating Postfix and" href="node13.html"><img src='next.png' border='0' height='32' alt='Next Page' width='32' /></a></td> <td align="center" width="100%">GNU Mailman - Installation Manual</td> <td class='online-navigation'><img src='blank.png' border='0' height='32' alt='' width='32' /></td> <td class='online-navigation'><img src='blank.png' border='0' height='32' alt='' width='32' /></td> <td class='online-navigation'><img src='blank.png' border='0' height='32' alt='' width='32' /></td> </tr></table> <div class='online-navigation'> <b class="navlabel">Previous:</b> <a class="sectref" rel="prev" href="mail-server.html">6 Set up your</a> <b class="navlabel">Up:</b> <a class="sectref" rel="parent" href="mail-server.html">6 Set up your</a> <b class="navlabel">Next:</b> <a class="sectref" rel="next" href="node13.html">6.1.1 Integrating Postfix and</a> </div> </div> <hr /> <span class="release-info">Release 2.1, documentation updated on December 14, 2009.</span> </div> <!--End of Navigation Panel--> </body> </html>
