Does anyone know a way that I can setup notification for emails that are undeliverable due to a Blacklist entry response from the receipient's SMTP server?
I have a customer that get's blacklisted and it would be nice if I was proactive and knew when the emails fail before they call me!!!
I usually have to manually telnet from my Exchange server to the receipients mail server before I know why the emails do not route properly and I immediately see a response of "Connection failed due to Blacklist on server....."
Thanks in advance
