We have exchange 2003 server standard edition and for some users I don't want to give them option to send out emails directly to SMTP.
I mean what ever emails they are sending from their account will go to a particular email id and he will check it and send it later.
For eg. if what ever emails sending out from user 'X' will go to user 'Y' only, But I want to do this only for external email address. those emails he is sending local users can be delivered.
Please advise how to do in exchange
