		<description><![CDATA[This morning at approximately 7am central time, our MF2 gateway began to experience issues. Although the gateway was up and responding to network requests, it was not responding to SMTP requests. After investigating the issue it appears that the gateway was hit with an extremely heavy dictionary attack, essentially to the point of a denial [...]]]></description>

		<description><![CDATA[We moved our DNS servers several weeks ago, but apparently one of the OpenDNS servers had the wrong information cached. This was rectified a couple of days ago, which is why we are seeing these problems today.  Now, there are several senders that still have bad DNS information cached.  If you are not receiving messages [...]]]></description>
