This may be a silly question, but why do you want to do this?  For most
legitimate purposes one SMTP server is as good as any other.  If your
staff's home computers are already configured for their ISP, why go to
the trouble of reconfiguring them all?  It won't matter from your ISPs
server's perspective whether their email address is
something at your.org.au or something at isp.com.au.  There are probably
situations where you do *need* to do what you're trying to do but there
are also plenty of situations where you don't.
