This setting determines the moderation policy of the
newsgroup and its interaction with the moderation policy of the
mailing list. This only applies to the newsgroup that you are
gatewaying <em>to</em>, so if you are only gatewaying from
Usenet, or the newsgroup you are gatewaying to is not moderated,
set this option to <em>None</em>.
<p>If the newsgroup is moderated, you can set this mailing list
up to be the moderation address for the newsgroup. By selecting
<em>Moderated</em>, an additional posting hold will be placed in
the approval process. All messages posted to the mailing list
will have to be approved before being sent on to the newsgroup,
or to the mailing list membership.
<p><em>Note that if the message has an <tt>Approved</tt> header
with the list's administrative password in it, this hold test
will be bypassed, allowing privileged posters to send messages
directly to the list and the newsgroup.</em>
<p>Finally, if the newsgroup is moderated, but you want to have
an open posting policy anyway, you should select <em>Open list,
moderated group</em>. The effect of this is to use the normal
Mailman moderation facilities, but to add an <tt>Approved</tt>
header to all messages that are gatewayed to Usenet.
