Your best source of information in a situation like this is the SMPT log. You have to enable it then do some more test messages.

However, when I check the settings IPv6 has been enabled. Is there some place else I need to check to make sure it is enabled?

Smith Consultant and Exchange MVP http://TheEssentialExchange.com From: King's Kid [mailto:kingskid1002...@yahoo.com] Sent: Tuesday, November 30, 2010 9:41 AM To: MS-Exchange Admin Issues Subject: Email delayed going to one specific domain Hi all, Yesterday our Exchange server stopped sending email to one specific domain (our consultant). The only change that was made to the server was I put in a rule regarding the Deleted items folder for our users which I have since deleted. All other emails are being sent correctly and our consultant is receiving emails from other clients. We recently upgraded to this version of Exchange and I'm still learning all the ends and outs. I googled the issue and didn't come up with anything. Any help would be appreciated. We running Exchange 2k7 on Small Business Server 2k8.
