Ugly and complex, but, oh well.

So why not just take MSexChange out of the picture? Set up direct
authentication to gmail. SASL_README.html#client_sasl just as you
did, setting it up to authenticate to MSexChange.
Have your .forward invoke sendmail(1) with your gmail address as the
sender. Then maybe a transport_maps entry to force your gmail address
to use the gmail submission service.
