Restricting some external addresses with wildcards?

[Flashgordon]

Hi

I have Exchange 2003 and I have some users that have an external SMTP address which we use for sending messages to an SMS text messaging service via the internet. Unfortunately, this means they can also send and receive external e-mails. I want to be able to stop them from sending/receiving messages from any address other than from a particular domain, i.e. the one where the text messages go to. In the users account, you can set message restrictions to accept messages only from a specific list, but I wonder can you use a wildcard in this list so that you can enter a whole domain in one entry?

Also, this option only restricts incoming messages, I haven't seen a way of restricting outgoing messages yet.

Any pointers?

Thanks

Andy.

I found this article regarding Exchange 2003. Not sure if it will help ...

Thanks for the reply but that option disallows ALL internet mail. What I want to do is allow traffic to/from a specific domain but disallow all other mail. Which is why I thought a wildcard might be needed.

I think this may be possible using SMTP connectors. It looks like you should be able to specify a connector thich routes all mail, and another that routes only the domains I want selected users to use, and give different access to these 2 connectors. I'm unsure about how to do it, though, anyone help?
