I am running Exchange 2003. I have a sender that when he sends an email to the President it bounces back But he can send to anyone else in our domain and it goes through.
The message he receives back is: Unable to deliver message to the following recipients, due to being unable to connect successfully to the destination mail server.
In the details.txt file attachment this is the message:
Arrival-Date: Tue, 4 Oct 2011 14:40:52 -0500
X-Display-Name: Shawn Smith
Have checked his Outlook for blocked sender. Checked spam filter settings
Checked Message Tracking Center
SMTP: Message Delivered locally to Shawn@mydomain.com
SMTP: Message Scheduled to Retry Local Delivery
And this just keeps repeating. If someone else is copied on it, they receive it in our domain
I'm scratching my head, anyone have any ideas?
