In Exchange 2003, how can I determine why specific emails were rejected (NDR)?
I have attached three screenshots of email message history where I am trying to determine why these three emails were rejected.
Do I need to enable more detailed (verbose) logging or something?
If so, please describe in detail how I can enable this more detailed (verbose) logging.
In the future, I need to be able to determine exactly why emails are rejected and aren't delivered to their recipients.
