Hi Edward, please do not top-post. Unfortunately you still provide insufficient information to be able to provide you best help. Did you read the complete list of information I asked in my last mail? You just go on and repeat a snipplet of sendmail.mc we already have seen multiple times. If your mail server IP is already blacklisted in cbl.abuseat.org, then this is a difficult starting point and a bad base for running mail services. Why are you listed? Alexander
