Instead of using localhost how about you set the NS record to
'baddns.vix.com' and have an A record pointing to some of your dead
IP space. That way the RBL client on the mail server will wait for a
while attempting to connect to a dead machine. This will create a
log jam at the inbound SMTP daemon, spinning off lots of processes,
hopefully jacking up the load on the box and tweaking somebody's
interested. Maybe even a tarpit type machine that can string the RBL
client along long enough to cause enough delay/processes on the
server to mean something. It is probably safe to assume if they are
still using the domain after 8 years they probably don't have
timeouts set for the RBL client lookups. Route the dead IP to a
bogus LAN so you don't ARP yourself to death.
