Code to determine if RDNS name is a dialup/dsl

We use this code on our systems to determine if a machine is a dialup/dsl host
(eg more dodgy and subject to more checks like greylisting, enumeration
detection, etc). Empirically, it seems to be pretty accurate these days
assuming that the machine has any rdns at all. If not, we assume it's on the
dodgy list.
