A lot of the big commercial services like AOL are also blocking mail that 
comes from IP addresses that are defined as Dynamic.  Frequently these aren't 
even checked by DNS, they're compared to some service that lists known blocks 
of dynamic addresses used by ISP's around the world.  I've had a number of 
mail services bounce messages from my server because it's in a RoadRunner 
address block.

Again, if this is for personal use there are ways around it, if it's for 
commercial use you need to get a commercial account which will come with a 
fixed IP address and legitimate reverse-DNS.
