This section contains the modeation controls for postings from both members and non-members. <p> <dl> <dt><strong>default_member_moderation</strong></dt> <dd>Member postings are held for moderation if their <em>moderation flag</em> is turned on. Note that only the list administrators can change the value of a member's moderation flag. <p> You can control whether new members get their moderation flag turned on or off by default when they subscribe to the list. By turning this flag off by default, postings by members will be allowed without further intervention (barring other restrictions such as size or implicit recipient lists - see below). By turning the flag on, you can quarantine new member postings to make sure that they meet your criteria for netiquette, topicality, etc. Once you determine that the new member understands the community's posting rules, you can turn off their moderation flag and let their postings go through unstopped. <p> E-newsletter style lists can also be set up by using the moderation flag. By setting the <code>member_moderation_action</code> to <em>Reject</em>, and by turning off the moderation flag for just the few approved senders, your list will operate in essentially a one-way direction. Note that you'd also need to reject or discard postings from non-members. <p> </dd> <dt><strong>member_moderation_action</strong></dt> <dd>This is the action to take for postings from a member who's moderation flag is set. For typical discussion lists, you'll likely set this to <em>Hold</em> so that the list moderator will get a chance to manually approve, reject, or discard the message. For e-newsletter and announcement lists, you might want to set this to <em>Reject</em> or <em>Discard</em>. <p> Note that when a moderated member posts to your list, and the <code>member_moderation_action</code> is set to <em>Hold</em>, the message will appear on the administrative requests page. When you dispose of the message, you will be given an opportunity to clear the moderation flag at the same time. If you're quarantining new posts, this makes it very convenient to both approve a new member's post and de-moderate them at the same time. <p> </dd> <dt><strong>member_moderation_notice</strong></dt> <dd>When a member's moderation flag is turned on and <code>member_moderation_action</code> is <em>Reject</em>, this variable contains the text sent in the rejection notice. </dd> </dl> <p> The next batch of variables controls what happens when non-members post messages to the list. Each of these accepts one email address per line; regular expressions are allowed if the line starts with the (caret) character. These address lists are always consulted in the order in which they're presented on this page (i.e. accepts first, followed by holds, rejections, and discards). <p> <dl> <dt><strong>accept_these_nonmembers</strong></dt> <dd>Postings from non-members whose addresses match this list are accepted, barring other list restrictions due to size, implicit recipients, etc. You might want to add alternative addresses of approved posters to this list. <p> </dd> <dt><strong>hold_these_nonmembers</strong></dt> <dd>Postings from non-members whose addresses match this list are held for moderator approval. <p> </dd> <dt><strong>reject_these_nonmembers</strong></dt> <dd>Postings from non-members whose addresses match this list are rejected, i.e. bounced back to the original sender. There currently is no way to add additional text to the rejection message. <p> </dd> <dt><strong>discard_these_nonmembers</strong></dt> <dd>Postings from non-members whose addresses match this list are discarded, with no bounce back message. You might want to add the addresses of known spammers to this list. <p> </dd> <dt><strong>generic_nonmember_action</strong></dt> <dd>This variable controls what happens to non-member posts when the address of the sender doesn't match any of the above four lists. If you set this to <em>Hold</em>, the posting will appear on the administrative requests page, and you will be given an opportunity to add the non-member to one of the above four lists at the same time you dispose of the held message. <p> </dd> <dt><strong>forward_auto_discards</strong></dt> <dd>When messages from non-members are discarded, either because the sender address matched <code>discard_these_nonmembers</code>, or because <code>generic_nonmember_action</code> is <em>Discard</em>, you can choose whether such messages are forwarded to the lsit administrators or not. </dd> </dl> <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="2.7.1 subscription rules" href="node21.html"><img src='previous.png' border='0' height='32' alt='Previous Page' width='32' /></a></td> <td class='online-navigation'><a rel="parent" title="2.7 the Privacy Options" href="node20.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="2.7.3 recipient Filters" href="node23.html"><img src='next.png' border='0' height='32' alt='Next Page' width='32' /></a></td> <td align="center" width="100%">GNU Mailman - List Administration Manual</td> <td class='online-navigation'><a rel="contents" title="Table of Contents" href="contents.html"><img src='contents.png' border='0' height='32' alt='Contents' width='32' /></a></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="node21.html">2.7.1 Subscription rules</a> <b class="navlabel">Up:</b> <a class="sectref" rel="parent" href="node20.html">2.7 The Privacy Options</a> <b class="navlabel">Next:</b> <a class="sectref" rel="next" href="node23.html">2.7.3 Recipient Filters</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>
