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.
