I do agree completely. However as is made clear by this exact case, there are enough inbound mail servers still left on this planet that do not follow that rule so as to make it worthwhile for spammers to continue to go to great lengths... even hijacking old & abandoned legacy IPv4 blocks... to get "fresh" IP addresses, even if they can't set up any reverse DNS for those. In a way, this case shows just how desperate spammers have become in their search for "fresh" IP addres space. Regards, rfg
