Hi,
My global IP address is blacklisted. I checked with mxtoolbox and whatsmyipaddress, Iam only listed on 9 lists. I checked my network, installed antivirus on all PC's on the network, stopped port 25 on all PC's and use SSL on outlook. I have an exchange server 2013 by the way. I tried removing the IP from these lists many times, but it comes back on saying my IP is sending spam. Please help.

Are all the PC's on your network and the Exchange server sharing the same public IP address? What is that IP address?
