One of my users is trying to send an e-mail to the following domain" tranquility.net" in response we received the following error message "The message cannot be delivered due to a configuration error on the server. Please contact your Administrator.
< tranq1.tranquility.net #5.3.0 X-Unix; 73>
we don't use any unix servers in my company, we have an Exchange 2003 server and my user is using Outlook 2007 Pro. My question is "is the problem on my end or on the recipients end? if the problem is on my side how can I fix it?
I will aprreciate any suggestions.
