KISS.
Virtual users on Exim
Submission with TLS on port 587, optionally a few 'custom' ports if firewalling
even that one is an issue.
Sync the Exchange userlist and auth creds as well, just in case (LDAP export?)
Road well-traveled, (Linux or Unix) and copious examples in docs and archives
here, including several folks who 'do' Exchange integration. To the extent one
can do, anyway.
