if all happend as you told, you did the right react, and there isnt much more you can do, additional perhaps search advanced aggressive users which are customers at this isp and inform about dropping mail to them, not longer getting your newsletter etc , usally companies react better when they get asked by people from which they want money, in heavy cases this might be work for lawers whatever your story isnt rare as might you think, there are some big mail isp out there ,which postmaster support is a desaster -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria
