I am wondering, everytime someone from within our organization attempts to send something to someone with an address that ends in @att.net, it ends up in the Queue, and the user gets a:
Subject: Delivery Status Notification (Delay)
This is an automatically generated Delivery Status Notification.
THIS IS A WARNING MESSAGE ONLY.
YOU DO NOT NEED TO RESEND YOUR MESSAGE.
Delivery to the following recipients has been delayed.
What could be causing this??? I’ve been looking at other posts but havent really found anything that might remedy this. Every other domain that is sent to seems to go through fine. This att.net one always hangs up. Is this something that an SMTP connector may help resolve? I have been reading about them, but cant seem to grasp exactly what they do, and whether or not one can be setup to just deal with mail to that att.net domain.
