Issue receiveing emails from certain mail servers. eg Office365 & Outlook.com
I am having issues with emails sent to one of my customers (SBS2003 / Exchange 2003 (Version: 6.5.7638.1).
I have asked for any NDR's to be sent to me and this is what they are saying:
XXXX@XXXX.com
9/6/2015 12:32:24 PM - Remote Server at mail1.XXXX.com (XXXX) returned '550 4.4.7 QUEUE.Expired; message expired'
9/6/2015 12:12:19 PM - Remote Server at mail1.XXXX.com (XXXX) returned '451 4.4.0 SMTPSEND.SuspiciousRemoteS
Original message headers:
Received: from DB5PR04MB1301.eurprd04.pro
DB5PR04MB1303.eurprd04.pro
Server (TLS) id 15.1.262.15; Fri, 4 Sep 2015 12:29:47 +0000
Received: from DB5PR04MB1301.eurprd04.pro
DB5PR04MB1301.eurprd04.pro
15.01.0262.011; Fri, 4 Sep 2015 12:29:47 +0000
I applied Hotfix 948963 (https://support.microsoft.com/en-us/kb/948963) last night but this stopped emails being received from my Exchange 2007 Server. I have since removed this and emails are being delivered again.
Any help would be appreciated.
Many thanks.

I'm suspecting you're using a third party filter/firewall software/hardware solution? In that case, you have to check the rules if there's anything you can whitelist MS servers.

Thank you for your comment. I have no third party filters running. The firewalls don't seem to be an issue either.
Does that mean whitelisting all MS 3rd party Servers manually? Is there a list of the ones used?
Thanks again.
