What is an ideal architecture for OWA?

Management wants to deploy Outlook Web Access (OWA) a.k.a. webmail.

There is a "debate" among the colleagues to place the front-end of the OWA
in the DMZ, which in turn talk to the Exchange Server in the internal
network, or to deploy ISA, as a reverse proxy server, in the DMZ.

Your thought is much appreciated.

Thanks,

DF
