It probably would help other people so I don't think most people will 
object to continuing here.

So postfix is serving what purpose to the internal users?  Only intranet 
email?

I'm not sure what your entire network looks like.  Until knowing that, 
we can only speculate.  Are they using the postfix server for general 
use or are they using a mail client on their workstations to communicate 
with some external email server?

You could have users send mail through the postfix server.  (Set your 
postfix server as the smtp server on each client).  If you need to send 
to outside servers, you can identify an smtp relay server in the main.cf 
file.  You _may_ have to insert a line in your /etc/hosts file on the 
postfix server to show that fax.yourdomain.com is your postfix box, but 
I don't think that's necessary.
