With access to Delivery Manager Message Traffic Graphs, it is easy to determine what traffic is flowing through the message security service:
In the Administration Console, select the appropriate email server from the pull-down list or the Show Hierarchy window.
Click the Inbound Servers tab, then the Delivery Manager link. View the Message Traffic Graph:
The graph will show whether or not traffic is flowing through the message security service. Each gray bar represents one minute.
The Current Activity box in the upper right-hand corner of the Delivery Manager overview page also shows statistics for the current email server config.
