We are running Exchange 2007 with a barracuda Spam Filter. I added the domain as a white list but when we try to send them an email with a PDF attachment, we get this diagnostic information. (please note, the email server and addresses have been changed for security purposes).
Is this error on my end or on theirs? How is this determined. The Generating server (mail.blank.lan) is on my end...
What could be causing this and how do I resolve?
Diagnostic information for administrators:
