This feature may not be available on all platforms. Please check your system's actual page if your device delivers this feature.

The system is designed with an Antispam function, which enables user to identify and filter mails transmitted by SMTP and POP3 protocol through the cloud server, timely discover the mail threats, such as spam, phishing and worm mail, and then process the found spam according to the configuration, so as to protect the user's mail client or mail server.

 The Antispam function will not work unless an Antispam license has been installed on a StoneOS that supports Antisspam.
