I have an Exchange Server 2003 server. I have a person outside the organization with an AOL account who is trying to email into our email server. When they email in with a new message they get the following error:
This is an automatically generated Delivery Status Notification.
Delivery to the following recipients failed.
They say that is all it says.
However, they can reply to any message we send with no problem. I am not sue what the issue is. Any help would be apprecaited.
