In order to restrict users from sending Internet based mail, you will need to create an SMTP connector, you cannot place this restriction on the SMTP Virtual Server.<br />
<br />
1. &nbsp; &nbsp; &nbsp; Create a Mail-Enabled Group and give it a meaningful name, I am going to call ours “No Internet Mail”, make sure you Mail-Enable this group.<br />
<br />
2. &nbsp; &nbsp; &nbsp; Add the users who will not have the ability to send Internet based mail into this group.<br />

I have a user who appears to be abusing the email to write a friend outside the org. &nbsp;The manager has asked me if I could limit this user send mail only to recipients within the organization. &nbsp;This is on Exchange 2003, and Oulook 20003.<br />
Thank you.
