Hi, > I'd argue with your interpretation of this licensing spec.

Well I just got off the phone with my Microsoft Licensing rep (a MS employee, not a local distributer or partner) and after a detailed discussion, he agrees with the above interpretation, i.e. all forwarded users would definitely need CALs just like any other user, because the email is indeed hitting the Exchange server and using it's resources.
