Ask your recipient how many emails an hour they’re receiving from your domain. They may be throttling you due to an excessive number of emails.
We just had this happen, where we were the ones not receiving. It turned out that the domain we had to throttle was sending us over 250 emails per hour which was above our threshold. 98% of the emails trying to come to us had no recipient defined. The issue was at the sender end. I have not been advised what they did to correct. Our concern was that they had a compromised PC that was sending many emails, likely via telnet since there was no recipient defined.

From: King's Kid [mailto:kingskid1002...@yahoo..com] Sent: November-30-10 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.
