Prevent users from sending mail using SMTP Connector Exchange

[markmcelhone]

Hi,

running Small Business Server 2003. All mail comes in over SMTP and works perfectly. Now I have created a second SMTP connector where emails to a certain domain are all sent through. This too works perfectly. What i want to do is prevent certain users using this connector, is there something i need to configure within the new SMTP connector? I have tried, within the SMTP Connector properties > Delivery Restrictions > Reject Messages from, adding users so they cant send them through it but still goes. The Address Space on both has the cost set at 1, would this have an effect?

If you need anymore info please just state
