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 email is not marked as spam. Select this radio button to have the device discard spam SMTP email. 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. Apply Reset 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.
