		<description><![CDATA[MF2 is currently undergoing emergency user database maintenance to help improve performance on the gateway.  During this time mail services are stopped and mail will queue on sending servers, to be delivered normally within 4 hours based upon retry settings at the sender.
Emergency maintenance is expected to take approximately 30 minutes.

Mail being temporarily deferred means that the gateway is responding to SMTP requests, but rather than accepting messages is responding with a 451 error to the sending [...]]]></description>
