While Mailman's bounce detector is fairly robust, it's
impossible to detect every bounce format in the world. You
should keep this variable set to <em>Yes</em> for two reasons: 1)
If this really is a permanent bounce from one of your members,
you should probably manually remove them from your list, and 2)
you might want to send the message on to the Mailman developers
so that this new format can be added to its known set.
<p>If you really can't be bothered, then set this variable to
<em>No</em> and all non-detected bounces will be discarded
without further processing.
<p><b>Note:</b> This setting will also affect all messages sent
to your list's -admin address. This address is deprecated and
should never be used, but some people may still send mail to this
address. If this happens, and this variable is set to
<em>No</em> those messages too will get discarded. You may want
to set up an
<a href="?VARHELP=autoreply/autoresponse_admin_text">autoresponse
message</a> for email to the -owner and -admin address.
