Its asuming its local users, you could do this in a different way. Put in
a entry in the mailertable. (/etc/mail/mailertable)

Like this:

bgp-expert.com                          smtp:[mail.bgp-expert.com]

If you put in your domain, and the hostname of your exchange box it should
go a little better i think. The linux box forwards all mail for the
mentioned domain to mail.<something>

Thats depending on some other settings. Did you accidently add for
example the domain you relay for in the /etc/mail/local-hostnames ?

Bye,
Raymond.
