If it is all postmaster@ then it is NDR spam, which will be cleared by using he link above to my web site. <br />
If you want to clear the queues, then see my spam cleanup article: <a href="http://www.amset.info/exchange/spam-cleanup.asp" rel="ugc">http://www.amset.info/exchange/spam-cleanup.asp</a><br />

<div class="content wysiwyg-content">
When I click on the Queues node in ESM, in the right-hand pane I see tens of<br />
listings which read: &quot;Internet Mail (SMTP) Connector (&lt;server_name&gt;) - &lt;some strange websites&gt; (SMTP Connector)&quot;<br />
The in the Message Tracking Center I see hundreds of Delivery Status Notification (Failure) messages.<br />
So I assume that this is spam: all those websites are trying to send me messages that are not delivered, so my postmaster is notifying them of NDR.<br />
How can I stop them from even hitting my server?
