My Exchange Server is Blacklisted I think.
Some people cant send email to me.
My Server is only a week old and 2 or 3 domains so far cant send email to me they get the message below. (I have checked and I am not Blacklisted but the IP address I am using was Backlisted approx. 2 years ago) if that makes any sense.
