Unless he does away with the entire domain (de-list his DNS servers
from the server list for that domain, stop serving monkeys.com
entirely).  The problem there, of course, is that he may still be
wanting to use the non relays.monkeys.com parts of the domain.  But the
only way I really see he can stop the problem is to remove his DNS
servers from the domain registration for monkeys.com.
