So, instead of fixing the problem, you do not want the problem to be found. Well, sorry to tell you, but if there is a way to relay through that server, you can bet that spammers will find it. Tell him to get off his but, find out why he is listed, and take corrective action. ORDB.org serves a great purpose and is helpful. If you do not understand why, then try posting the actual domain and mail server in question, and we can help.
