Juz a quick check on the Exchange 2003 SMTP connector. If we forward all the messages to the smarthost instead of the DNS, will the SMTP restriction like Reject message from still can be applied.
Coz i have tested out this to try to restrict certain user to send internet email. But the user is still able to send out the email. I believe it the restriction wont apply in this case. Pls correct me if i'm wrong.
