Firstly, are there any reasons, other than email, for which you need
"" configured within your network/AD?

If not then my suggesion is to:
- remove the recipient policy for "" from your Exchange
- all mail (from the internet and from the local staff) to
will go to the unix box
- when you decide that your staff really need to start using the
exchange server for then set the recipient policy
accordingly and change the MX records in your zonefiles and the ISP's
zonefiles to point to the exchange server. 

For a short while email from the internet will be sent to both the unix
server and the exchange server, at least until everyone's DNS records
are updated.  At the same time, your staff now send internally only.
Just ensure that your staff collect email from the unix box (POP3).

Hoep that helps,
