I've have a client who has a ton of mobile users that need to be able to send email out wherever they are. I have set up relaying in the past for other clients in the same situation. Basicly the client provides a user with a pop email account we cant use RPC over HTTP because we dont have control of the user's email client. What I want to do is open up the Exchange 2003 server SP2 to allow relaying from authenticated users.
This should be really simple, except it isnt working. I have gone through all the the instructions on how to do this and it still will not allow me to relay as an authenticated user. I can relay if I put in a specific IP address but that doesnt help me. Is there something new with SP2 that completely turns off this feature??
The environment is simple.. One Server, AD and Exchange providing POP email.
Any help or hints??
