Wiser minds may say otherwise but on the face of it I would say you
cannot do it.

I have to ask- why do you wish to do that? It may help if you explain
the reason behind this request or any constraints.

One suggestion would be to set up recipient policies for
"" rather than "".  That way, a DNS lookup
for "" will determine that the mail should be sent to the
UNIX server (depending upon how your DNS is set up, of course).  This
may not be what you want though, hence my question- why do you want to
do this?

Or, is it that you wish the staff to be able to send mail out as
"user@xxxxxxxxxxxx".  If so, you may need to remove the recipient policy
and then set up a POP3/SMTP account in Outlook to send mail as that
email address.

Anyway, that is just a suggestion.
