You know, we just had this problem, and I think I solved it (for us, 
anyway).  Apparently, some services want your reverse DNS to match your 
forward DNS.  So, if I log in with 10.0.0.1, they reverse to 
somehost.mydomain.com, then the forward for somehost.mydomain.com should 
exist too.  We were having users who couldn't get onto IRC with this, 
claiming there was a reverse DNS problem, which I could verifiably do 
reverse DNS from any random DNS server.  We added the forward references, 
and our problems disappeared.

Strange, huh?
