When I try to send mail from my Exchange 2003 server I get the following error message.
'email@example.com' on 12/6/2007 3:59 PM
There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.
<ADSEMAINDC2.adsemain.com #5.5.0 smtp;550 No such domain at this location (firstname.lastname@example.org)>
I have logged onto our exchange server and gone to the command prompt and was able to look up the mx record for doremusfp.com. I was also able to also establish and smtp session through the command prompt to their mail server.
The question is why am I getting the error saying it can not find the domain?
