We have an Exchange 2003 server handling internal and external mail, using one Exchange Organisation. There is no problem setting the connector to route external mail to the smarthost, but internal mail (from email@example.com to firstname.lastname@example.org etc) is just sent without being checked by the smarthost. SMTP is set to route all mail to the smarthost, but how do we get the internal mail to do the same? Internal mail is just moving about in the same domain, and is almost more important to monitor than that being received and sent externally. Ideas?
