You need to explicitly allow Mailman's wrapper program to be used with smrsh or Mailman will not work. If mail is not getting delivered to Mailman's wrapper program and you're getting an ``operating system error'' in your mail syslog, this could be your problem. <p> One good way of enabling this is: <p> <ul> <li>Find out where your Sendmail executes its smrsh wrapper <p> <div class="verbatim"><pre> % grep smrsh /etc/mail/sendmail.cf </pre></div> <p> </li> <li>Figure out where smrsh expects symlinks for allowable mail programs. At the very beginning of the following output you will see a full path to some directory, e.g. <span class="file">/var/adm/sm.bin</span> or similar: <p> <div class="verbatim"><pre> % strings $path_to_smrsh | less </pre></div> <p> </li> <li>cd into <span class="file">/var/adm/sm.bin</span>, or where ever it happens to reside on your system - alternatives include <span class="file">/etc/smrsh</span>, <span class="file">/var/smrsh</span> and <span class="file">/usr/local/smrsh</span>. <p> <div class="verbatim"><pre> % cd /var/adm/sm.bin </pre></div> <p> </li> <li>Create a symbolic link to Mailman's wrapper program: <p> <div class="verbatim"><pre> % ln -s /usr/local/mailman/mail/mailman mailman </pre></div> </li> </ul> <p> <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="6.3 using the Sendmail" href="node31.html"><img src='previous.png' border='0' height='32' alt='Previous Page' width='32' /></a></td> <td class='online-navigation'><a rel="parent" title="6.3 using the Sendmail" href="node31.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="6.3.2 integrating Sendmail and" href="node33.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="node31.html">6.3 Using the Sendmail</a> <b class="navlabel">Up:</b> <a class="sectref" rel="parent" href="node31.html">6.3 Using the Sendmail</a> <b class="navlabel">Next:</b> <a class="sectref" rel="next" href="node33.html">6.3.2 Integrating Sendmail 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>
