On the other hand, checking the PTR and A records for an inbound connection
for sanity often reveals a DNS hack attempt. Or that's the theory anyhow.
Personally, I treat a PTR check as a clue-meter for the ISP involved - if
they have a broken DNS, they're probably lame enough to also be infested with
hackers, spammers, and other low-lifes....
Let the flaming commence ;)
