Andy, Problem isn't white/grey/black listings, its that they accepted the email with a valid return code but it never made it to the destination box. It only seems to be happened on a few recipients. Basically, in short, the destination ISP (in this case ATT) is making some type of decision as to what email you are receiving. Buying additional technology won't exactly solve this problem.
