Action taken when mail
sessions threshold is
reached
The anti-spam feature limits the number of concurrent e-mail sessions. An e-
mail session is when an e-mail client and e-mail server (or two e-mail
servers) connect through the device. Use this section to configure what the
device does when the number of concurrent e-mail sessions goes over the
threshold (see the appendix of product specifications for the threshold).
Select Forward to have the device allow the excess e-mail sessions without
any spam filtering.
Select Block to have the device drop mail connections to stop the excess e-
mail sessions. The e-mail client or server will have to attempt to send or
receive e-mail later when the number of e-mail sessions is under the
threshold.
Apply Click Apply to save your changes back to the device.
Reset Click Reset to begin configuring this screen afresh.
