Chapter 2 Using Email Security Monitor
The incoming mail page shows incoming connections, the total number of incoming messages, the
average message size, and the total incoming message size. You can limit the results to the time range
that you specify. It is important to have an understanding of the trends of normal message volume and
spikes in your environment. You can use the incoming mail page to help track volume growth over time
and plan for system capacity. You might also want to compare the Incoming Mail data with the Sender
Profile data to view the trends in volumes of emails that are being sent from specific domains to your
network.
Note an increased number of incoming connections may not necessarily affect system load.
