We have a routing group from one site to another site. Some email from other site is coming through this routing group to our Exchange 2003 server but some is coming from the internet. They want us to find and report which messages are routing properly through the routing group vs coming from the internet. Can exchange natively be configured to monitor the headers and copy a user and/or archive messages based on header content? I think not but please sugges a third-party tool for this if not. Thanks!
