I would like Exchange to copy/forward all incoming emails to a test email server which is on our network. I am testing a second email system running on Linux and would like this test server to receive the same emails that the Exchange server is receiving, whether it's comming from local Exchange users or from the Internet. Regular users still get their emails from the Exchange server. Sending from the test server is not required - I just need to populate the test server with the incoming mail.
How can I configure this in Exchange ?
