Mail transport protection
SMTP server-level filtering is secured by a specialized plugin that provides protection with antivirus, antispam, anti-phishing and user-defined rules.
|
Mail transport protection is applied to Inbound messages and Outbound messages are scanned on the Database level. |
When a message arrives through the SMTP, the following actions are taken in the scanning sequence:
1.The message is scanned using the Greylisting technique (if enabled). For more information, refer to the chapter antispam protection.
2.The message is then scanned by the user-defined rules. Refer to the chapter rules for more information on how they work.
3.The message is scanned by the antispam module.
4.The message is scanned by the antivirus module.
Appropriate action is taken if the message is infected or recognized as spam. If the message is clean, it will be delivered to the recipient.
