Make sure under connections that all except below is checked and that nothing exists in the box. Under relay only the list below should be selected and the list should be empty unless you have a machine that has to talk to port 25 it needs be listed. Generally it will be empty. Also make sure that the allow all aunthenticated box is checked.

Does any one have any idea what could be going on? Currently I have the public IP in the Access>Relay tab granted permission to relay mail. I also have the private IP granted access to relay mail. Any thoughts or help would be grateful.
