Outbound Exchange 5.5

I'm afraid it's all or nothing choice. Disabling mail relaying would disable relaying all mail outside your office.

Perhaps you could try grouping users that you don't want to send outside mail on one server and apply this restriction on that server.

In the Exchange Admin Connections container Double click the IMS or click and hit the properties button, Then click on the Delivery Restrictions tab. If you add users to the Accept messages from list these people can send external mail, and if you add users to the Reject messages from list these people can't. You can have users in the list at the same time and you can use a DL

You can use the Routing tab in the Internet Mail connector properties to do this. Note, however, that this is done by workstation IP address, not by user, so that if someone moves from one workstation to another, you would have to change this table.

1. Open Exchange Admin, go to Connections and open the Internet Mail Service connector.
2. Click the Routing tab and then select the radio button for "Reroute income SMTP mail".
3. In the box you should see your domain name listed in the "Sent to" column and listed in the "Route to" column. If you don't, click the Add button and type in your domain name. Click the "Should be accepted as inbound" radio button and click OK.
4. Click the Routing Restrictions tab.
5. Clickthe check box for "Hosts and clients that successfully authenticate". This will allow all your authenticated clients to send mail except any that are otherwise excluded.
6. ALSO click the check box for "Specify the hosts and clients that can NEVERroute mail". Then you can specify the IP addresses of those clients that you don't want to allow to relay.

Hope this helps!

Answer 1 and 3 are wrong. Answer 2 is right. If you want also to disable incoming email (form outside your office) to that user, you can do that by deleting the SMTP mail address for that user (Exchnage only needs that for Internet Email and not forinternal email). To do that in Exchange Admin in the properties of that user go to the email address tab and delete the SMTP address.
If however you only want to disable outgoing you will have to do what Answer 2 says.
