Hi,
Assuming your are talking about Microsoft Exchange Server, the answer is YES, er... partially yes.
You must install exchange on 2 servers, same installation. In the first server you simple disable the service IMAP or POP (depending on what you want), and on the other you disable SMTP. So one server recive and the other send. Of course you must configure your clients in order to send / receive from / to the right server.
Regarding the email copy, I think is not possible, you could write a new rule for each mail sent... but I think you can only forward to a mailbox...
