Sorry to hear that you are having blacklist troubles. You can follow the links to the Blacklist websites (via the "details" link or the Blacklist name) and request delisting directly from them.
I also want to provide you with a link to a very handy article we posted on our blog - What Blacklists Are and How MxToolbox Helps!
The article will explain a lot about how our services eliminate the problems blacklists cause and how they are oftentimes recurring and hard to permanently fix.
If you can't get resolution to the problems, don't hesitate to call or e-mail me and we can discuss the problems further. Thank you!!
