In an Windows 2008 r2 domain with Exchange 2007, all email to clients from SBCGlobal.com are being delayed.
Here is the message being received by most employees:
Delivery is delayed to these recipients or distribution lists:
This message has not yet been delivered. Microsoft Exchange will continue to try delivering the message on your behalf.
Delivery of this message will be attempted until 11/12/2015 11:54:32 AM (GMT-06:00) Central Time (US & Canada). Microsoft Exchange will notify you if the message can't be delivered by that time.
No error messages are received. The Exchange queue is backed up for SBCGlobal only, no problem with any other domain
Has anyone else begun receiving this delay?
