It used to be that lots of things depended on this, but, with the advent
of the clueless internet, people have had to turn off this test.  I remember
when ftp.uu.net required you to have matching forward and inverse DNS.

Long gone are those days.  

Yes, _some_ things still require you to have working DNS, but the inability
for providers to get simple things working _right_ has brought the network
to a state of extreme apathy.

When the response by the ISP in the wrong is "well, you are one of very few
people that my clients can't talk to, so you must be broken", and that is
the line that they are feeding their clients, what are you to do?
