Here's an overview of how it works: + +<P> +When a bounce is received, Mailman tries to extract two pieces of +information from the message: the address of the member the message +was intended for, and the severity of the problem causing the bounce. +The severity can be either <em>hard</em> for fatal errors, or +<em>soft</em> for transient errors. When in doubt, a hard severity is +used. + +<P> +If no member address can be extracted from the bounce, then the bounce +message is usually discarded. Every member has a <em>bounce score</em>, +initialized at zero, and every time we encounter a bounce from a +member we increment that member's score. Hard bounces increment by 1 +while soft bounces increment by 0.5. We only increment the bounce +score once per day, so even if we receive ten hard bounces from a +member per day, their score will increase by only 1 for that day. + +<P> +When a member's bounce score is greater than the <em>bounce score +threshold</em> (see below), the member's subscription is disabled. Once +disabled, the member will not receive any postings from the list until +their membership is explicitly re-enabled, either by the list +administrator or the user. However, they will receive occasional +reminders that their membership has been disabled, and these reminders +will include information about how to re-enable their membership. You +can control both the number of reminders the member will receive and +the frequency with which these reminders are sent. + +<P> +There is one other important configuration variable; after a certain +period of time - during which no bounces from the member are received +- the bounce information is considered stale and discarded. Thus by +adjusting this value, and the score threshold, you can control how +quickly bouncing members are disabled. You should tune both of these +to the frequency and traffic volume of your list. <P> <DL> -<DT><STRONG>bounce_matching_headers</STRONG></DT> -<DD>This variable contains header regular expressions, one per line, - and if any of a message's headers matches one of these patterns, - it will be held for moderation. The format is a colon separated - header and value, where the header is case insensitive and the - value is any valid Python regular expression. Lines that start - with # are ignored. +<DT><STRONG>bounce_processing</STRONG></DT> +<DD>Specifies whether or not this list should do automatic bounce + processing. <P> -This variable can be used to catch known spammers by writing - regexps that match against <span class="mailheader">To:</span> or <span class="mailheader">Cc:</span> - lines, or known-bad <span class="mailheader">Message-ID:</span>s. Perhaps more useful - though are patterns that match headers added by spam detection - tools higher up in the tool chain. For example, you might - configure SpamAssassin to add an <span class="mailheader">X-Spam-Score:</span> header - with between zero and 5 stars depending on the spam score. Then - you can add a line to this variable like: +</DD> +<DT><STRONG>bounce_score_threshold</STRONG></DT> +<DD>This is the bounce score above which a member's subscription will + be automatically disabled. When the subscription is re-enabled, + their bounce score will be reset to zero. This value can be a + floating point number. <P> -<dl><dd><pre class="verbatim"> - X-Spam-Score: [*]{3,5} -</pre></dl> +</DD> +<DT><STRONG>bounce_info_stale_after</STRONG></DT> +<DD>Thenumber of days after which a member's bounce information is + considered stale. If no new bounces have been received in the + interrim, the bounce score is reset to zero. This value must be + an integer. <P> -This line will match from 3 to 5 stars in the value of this - field. +</DD> +<DT><STRONG>bounce_you_are_disabled_warnings</STRONG></DT> +<DD>The number of notices a disabled member will receive before their + address is removed from the mailing list's roster. Set this to 0 + to immediately remove an address from the list once their bounce + score exceeds the threshold. This value must be an integer. + +<P> +</DD> +<DT><STRONG>bounce_you_are_disabled_warnings_interval</STRONG></DT> +<DD>The number of days between each disabled notification. + +<P> +</DD> +<DT><STRONG>bounce_unrecognized_goes_to_list_owner</STRONG></DT> +<DD>This variable controls whether unrecognized bounces are discarded, + or forwarded on the list administrator. The bounce detector isn't + perfect, although personalization can make it much more accurate. + The list owner may want to receive unrecognized bounces so that + they can manually disable or remove such members. + +<P> +</DD> +<DT><STRONG>bounce_notify_owner_on_disable</STRONG></DT> +<DD>This option controls whether or not the list owner is notified + when a member's subscription is automatically disabled due to + their bounce threshold being reached. + +<P> +</DD> +<DT><STRONG>bounce_notify_owner_on_removal</STRONG></DT> +<DD>This option controls whether or not the list owner is notified + when a member is removed from the list after their disabled + notifications have been exhausted. </DD> </DL> <P> <DIV CLASS="navigation"> -<p><hr> +<div class='online-navigation'> +<p></p><hr /> <table align="center" width="100%" cellpadding="0" cellspacing="2"> <tr> -<td><A HREF="node24.html"><img src="../icons/previous.gif" - border="0" height="32" - alt="Previous Page" width="32"></A></td> -<td><A HREF="node21.html"><img src="../icons/up.gif" - border="0" height="32" - alt="Up One Level" width="32"></A></td> -<td><A HREF="node26.html"><img src="../icons/next.gif" - border="0" height="32" - alt="Next Page" width="32"></A></td> +<td class='online-navigation'><a rel="prev" title="2.7.4 Spam Filters" + href="node24.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 The List Configuration" + href="node8.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="2.9 The Archiving Options" + href="node26.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><A href="contents.html"><img src="../icons/contents.gif" - border="0" height="32" - alt="Contents" width="32"></A></td> -<td><img src="../icons/blank.gif" - border="0" height="32" - alt="" width="32"></td> -<td><img src="../icons/blank.gif" - border="0" height="32" - alt="" width="32"></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> -<b class="navlabel">Previous:</b> <a class="sectref" HREF="node24.html">3.7.3 Recipient Filters</A> -<b class="navlabel">Up:</b> <a class="sectref" HREF="node21.html">3.7 The Privacy Options</A> -<b class="navlabel">Next:</b> <a class="sectref" HREF="node26.html">3.8 The Bounce Processing</A> -<hr> -<span class="release-info">Release 2.1, documentation updated on October 2, 2004.</span> +<div class='online-navigation'> +<b class="navlabel">Previous:</b> +<a class="sectref" rel="prev" href="node24.html">2.7.4 Spam Filters</A> +<b class="navlabel">Up:</b> +<a class="sectref" rel="parent" href="node8.html">2 The List Configuration</A> +<b class="navlabel">Next:</b> +<a class="sectref" rel="next" href="node26.html">2.9 The Archiving Options</A> +</div> +</div> +<hr /> +<span class="release-info">Release 2.1, documentation updated on December 13, 2004.</span> </DIV> <!--End of Navigation Panel--> |
