I find iptables excellent for getting rid of this kind of problem.
e.g.
iptables -I INPUT 1 -s 1.2.3.4 -j DROP
You cease to exist for that ip address (1.2.3.4) on all ports (not
just smtp).
You can get rid of entire ip blocks, too
iptables -I INPUT 1 -s 207.71.8.0/24 -j DROP
Goodbye rackspace (well, some of rackspace). I don't recommend using
iptables in place of regular blacklists, but it's great for getting
rid of persistent jerks.
