CDO mail gets routed incorrectly... A DNS issue?

| Hi there.
I have a site with CDO mail that needs to send email to the internal
address of a mail server. The advertised MX record is a DNS name, and
this resolves to an external address.
I put an entry in the hosts file after which an smtp telnet to the
internal address works great from a dos prompt, however the CDO mail
still routes out to the external address.
Is there something odd in the way CDO or DNS works that I don't know
about just at the moment. It seems it isn't using the hosts file to
resolve the DNS name of the MX record.
TIA

Googleboy,
Open the IIS admin and select the default smtp virtual server and expand it.
Next
select the domains and right click selecting new domain and select remote, you
will be selected to enter the domain name. This should be the domain you are
trying
to send to Internally. You will now need to right click the domain and
select properties. Under the route domain section select "forward all mail to
smart host
and enter the IP address of the Internal mail server between
[xxx.xxx.xxx.xxx] or
it will not route the mail. Next stop and start the IIS ADmin service and
this Domain
should be routing to the correct server.
