⟩ How can I prevent a user from sending and receiving Internet mail?
Follow the steps outlined below:
1. Create a group called InternalOnly.
2. Create a recipient policy that gives them a fake SMTP address. i.e. @fake.domain. Leave the X400 address alone so they can receive internal mail.
3. Drill down through Routing Groups > Group Name > Connectors > SMTP internet connector(s), choose its properties. Choose the Delivery Restrictions tab, and under “reject”, add this group. Do this for each connector.
4. Follow the steps in KB277872, regarding Connector Restrictions.
[Now they ca not use the SMTP connector(s) to send external mail]
