DESCRIPTION
Enter a message or label (up to 16 ASCII characters) to add to the
mail subject of e-mails that the anti-spam external database
classifies as phishing.
Note: You must register for and enable the anti-spam external
database feature in order for the device to use this tag
(see the chapter on registration for details).
Enter a message or label (up to 16 ASCII characters) to add to the
mail subject of e-mails that the device classifies as spam.
Select this radio button to have the device forward spam e-mail
with the tag that you define.
Even if you plan to use the discard option, you may want to use
this initially as a test to check how accurate your anti-spam
settings are. Check the e-mail the device forwards to you to make
sure that unwanted e-mail is marked as spam and legitimate e-
mail is not marked as spam.
Select this radio button to have the device discard spam SMTP e-
mail. The device will still forward spam POP3 e-mail with the tag
that you define.
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.
Click this to save your changes back to the device.
