Delivery is delayed to these recipients or groups
Posted on 2012-03-12
We are trying to email some of our customers and after a long period of time we get an email from OUR exchange server that says Delivery is delayed to these recipients or groups.
We host our our Exchange 2010 server. About a week ago we switched our ISPs from Windstream to Time Warner Cable Business Class. However, we don't filter our outgoing email for spam or anything else. Why would we all of a sudden be getting these messages from our Exchange server?
