I suppose that Postfix is between the Internet and Exchange? Then I suggest using a virtual _mailbox_ domain for all the users (including the Exchange users that will be delivered elsewhere), with a transport mapping to deliver some of those users to the Exchange server. This way Postfix would never accept mail for bad email addresses. http://www.postfix.org/postconf.5.html#virtual_mailbox_domains http://www.postfix.org/postconf.5.html#virtual_mailbox_maps http://www.postfix.org/transport.5.html http://www.postfix.org/VIRTUAL_README.html Before going into configuration details I'll wait for other responses.
