* Assuming you are using Exchange Server 2003 and also that if user2@abc.com would be one of the default recipients for emails sent by user1@abc.com, then you could enable email forwarding using Active Directory Users and Computers console<br />
<br />
* In ADUC, select the user properties of user2@abc.com and in the Exchange General Tab, under Delivery Options button, you could set a forwarder to the user4@abc.com mailbox.<br />
<br />
* And if it is Exchange 2007 Server, then as mikainz quoted, you could use the Exchange Transport Rules on the Hub Transport server and accomplish this task as a piece of cake<br />
<br />
Good Luck (^_^)
