Hi, I would start by finding out why your server is blacklistet. Did you configure it as an open relay? You can test for open relay here http://mxtoolbox.com/ When you have closed the open relay you will be able to be removed from the blacklists. If you think that it is an internal client you need to find that client and find the issue with the client. Leif

hi, First check whether you are opening relay. >>>Because in my system some user used email spam email Use transport rule to remove all messages that sent from these users or depend on some key words to delete the spam mail. Find out why do they send spam mail? May be some virus. hope can help you thanks,CastinLu TechNet Community Support
