Need help with ALLOWING users to relay in Exchange 2003

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??

You have set the client to authenticate when sending email?
What are you using for a username for authentication when sending email?

username?
username@domain.com?
domain\username?

Something else?

Relay when authenticated is enabled by default.

However, this still will not guarantee that the users can send email. Many ISPs block access to remote SMTP servers and instead want you to send email via their servers.

tried all of the above.. it works fine on an exchange 2000 server I've got doing the same thing for another client.. This setup is almost identical. I know that some isp's block outgoing port 25 to try and stop viruses and spam and it drives me crazy. But I've got mobile users, in and out of hotels and on the road all the time. I need a better soltuion that everytiem they travel them call up my and tellign me they can send email. I guess I could just have them all use OWA. but that's cumbersome and they want to be able to use the fullly featured outlook.

maybe I'm just banging my head against the wall here and I need to lay down some rules.. so this might not be a technical question so much as a request for suggestions..

I really would like to know if they changed something in 2003 though or get this fixed.. It makes me mad I could setup a little 2000 exchange box that all it did was relay for me without a problem.

Have you configured the users who can authenticate? I always set specific users to be allowed to relay.

It certainly must be easy as spammers are constantly attacking SMTP servers to try and break the administrator password so that they can relay through the server.

For guaranteed delivery the best option is RPC over HTTPS. You are licensed to use Outlook 2003 with the Exchange 2003 CAL, so you could get the users to install Outlook 2003.
