The best way to avoid being put on a black hole list is to be vigilant about any abuse or misuse of your internal email system(s), to monitor any messages (including messages on the various anti-spam message boards) that may mention your company or its trademarks, and by establishing and maintaining an incident response capability (which includes, of course, advice from legal counsel) to help respond both to fictitious spam and to potential black holes.
