<h3><a name="SECTION002273000000000000000">
2.7.3 Recipient Filters</a>
</h3>

<p>
The variables in this section control various filters based on the
recipient of the message.

<p>
<dl>
<dt><strong>require_explicit_destination</strong></dt>
<dd>This controls whether the mailing list posting address must be
    explicitly named in the <span class="mailheader">To:</span> or <span class="mailheader">Cc:</span>
    recipient lists.  The main reason why it wouldn't is if the
    message was blind-carbon-copied (i.e. <span class="mailheader">Bcc:</span>'d) to the
    list.  Spammers like to do this, but sometimes legitimate messages
    are forwarded to the list this way.

<p>
If the list is not explicitly addressed and this setting is turned
    on, the message will be held for moderator approval.

<p>
</dd>
<dt><strong>acceptable_aliases</strong></dt>
<dd>This is the list of alternative addresses that are acceptable as a
    list posting address when <code>require_explicit_destination</code> is
    enabled.  This is useful for when there aliases for the main
    posting address (e.g. <code>help@example.com</code> may be an alias for
    <code>help-list@example.com</code>).

<p>
</dd>
<dt><strong>max_num_recipients</strong></dt>
<dd>This is the maximum number of explicit recipients that are allowed
    on the posted message.  Spammers sometimes send messages with lots
    of explicit recipients, so setting this number to a reasonable
    value may cut down on spam.
</dd>
