John,
What we did is we setup like you are talking about, and got as many of
the IP classes as we could, then we added the others as we got calls in. We
explained it as we were getting outside interference from un-ethical mailers
and were creating a setup that would halt this and make mail service faster.
No lying here, just explaining it in a positive way.
The other thing that you could do is try to get his IP and put it in the
kill list or if he is on a dynamic IP then kill his whole class.
Typed like this 90.0.0.0 255.255.255.0 this kills all 254 usable
addresses. This also can be used in the smtp access list to let in a whole
class but deny others.
