I setup a client's Exchange server to use my Iworx server as a SmartHost. I've setup the tcprules to allow their static IP to relay through my server, but they got on a blacklist that my server blocks and it's not letting their emails out.
Is there a way to also whitelist their IP from the blacklist at a global level?
