Alrighty, we have about 300 users who will need to send inter office mail. I only have 30 users I want to use internet email. I have deleted the smtp address for the 270 users, so they cannot recieve internet email. what do I have to do to prevent them from sending internet email without interfering with the internet email for the 30 people that need it?

Using Exchange Admin console, open the properties for the Internet Mail Service in the \Connections folder. Using the Delivery Restrictions tab you can customize the IMS to deliver mail based on the restrictions you set. Since your list of internet mail users is much smaller than that of your non-internet mail users, you may want to modify the "Accept messages from" list instead of the "Reject mesages from" list. You might also consider making a distribution list that only contains allof your internet mail users, and then add that distribution list to the "Accept.." list. When you modify the DL, your IMS restrictions are automatically updated.

Hope this helps, -Ewing

To prevent a user from sending outbound internet mail, set a delivery restriction on the Internet Mail Service to reject all messages from that user:

On the Internet Mail Service Properties page, click the Delivery Restrictions tab.

Under Reject Messages From, click List.

Click Modify, and click the mailbox you want to restrict.

The Internet Mail Service will now reject any outbound messages that it receives from that mailbox.
