Not as much as you might think. I didn't mention that MTA's/IP's that
are automatically whitelisted have an expiry time. Statically whitelisted
ips/hosts/netblocks dont expire.

1000 successfull triplets get hosts automatically whitelisted
for N days. That value is all dependant on the size of the
site you admin. Small sites will go for about 10 -> 50..
