jnyr Posted March 31, 2006 Share Posted March 31, 2006 Hi everyone. I manage an Exchange 2003 server for 3 users and this box keeps getting on various blacklists. I did every single test for open relaying and everything looks fine. I also configured Exchange for no NDRs and auto-reposnders; out of office, etc. Finally, I followed the MS article for SBS to clean up queues, etc. After delisting the server everything was fine for about 2 weeks. Then the server got re-listed. This server especially gets listed on CBL. I have no idea what else to look for. During the first listing, Yahoo also blocked my server. I contacted Yahoo and they "tested" my IP and confirmed that all problems have been resolved and that my server has been unblocked. Any help would be greatly appreciated. IP Address is 18.104.22.168.
