Those who do so should be doing one of the following.
a) Since you must be using dedicated IP space, have proper DNS setup.
Pacbell for example will change your reverse DNS for free to match the forward
name you assign to your server. (thus solving two problems at once)
b) Set your server to relay mail via your IP providors server or some other
server.
