You need to create an SMTP Connector and set the Delivery Restriction on that, Sender Blocking is for people trying to send to you.

We have a static IP for our domain. By default the user accounts which I create are having a facility to send e-mails onto internet. I need to block a user from sending e-mails to internet.. I did create enable sender blocking feature on exchange 2003. But it does not work. I also changed setting in SMTP Relay in which I said deny relay for this user account, but no luck. When I map the user's mailbox and test I'm able to send the e-mails to internet. Await your reply.
