The tests seem normal..no open relays as well. But my IP is still blacklisted on two lists, SORBS-SPAM and UCEPROTECTL1. SORBS-SPAM is even asking money for them to remove us from their list. I'm unable to determine now if what's still wrong or if there's still really a problem with my server. I'm completely lost now on what to do next. Hope you guys can help me on this.
I'm now considering changing the IP of my mail server if it will solve it. But if there is still a way to solve this, I will rather cross that path. Thanks guys.
