We are using Exchange 2010 to relay messages out to the Internet, and there are no local mailboxes, or accepted domains configured.
Mailflow works correctly, and we have a custom routing agent.dll installed.
We need to track a message sent from domain1.com to microsoft.com using SMTP. Since neither of these domains exist as an accepted domain, how do I track a message with this criteria?
The message tracking website in OWA requires me to select a mailbox.
