Concurrent Mail Session
Scanning
The darker shaded part of the bar shows how much of the ZyWALL/USG’s total
spam checking capability is currently being used.
The lighter shaded part of the bar and the pop-up show the historical high.
The first number to the right of the bar is how many e-mail sessions the ZyWALL/
USG is presently checking for spam. The second number is the maximum number
of e-mail sessions that the ZyWALL/USG can check at once. An e-mail session is
when an e-mail client and e-mail server (or two e-mail servers) connect through
the ZyWALL/USG.
