  For a guy like this, I like having iptables stop him.
  waste less of your resources, stops him early, why
  let sendmail process his garbage.

iptables -A INPUT -p tcp -s ***.***.76.53 --dport 25 -j REJECT
or
iptables -A INPUT -p tcp -s ***.***.76.53 --dport 25 -j DROP
might be better, as he won't know what happened!
