Trying to run the Server Internal vs External Activity report and zeros are displaying for external messages sent and external volume sent. Looking for a report that will display external traffic that comes into the bridgehead server and then routes to all other servers in the ORG. The report would be something like Bridgehead server traffic to mail server in the ORG.
All of the Server Activity reports display information that it actually transfers, and it does not know where the message will eventually end up. MessageStats does not have a report that says what were the number (and the associated volume) of messages that will eventually be external messages. This has been logged as a Feature Request and will be consider after the release of v5.0.
