Configures the block policy rule based on the IP address of the sender.
The appliance immediately marks an email for quarantine if it includes the sender IP address that you defined. A blocked list supports IPv4 and IPv6 addresses. All the recipients will receive a copy of the original malicious email with a different subject. In the Email Security — Server Web UI, an email can either be deleted or released from the eQuarantine page. For details about how to configure a blocked list, refer to the "Rule Configuration on Allowed and Blocked Lists" chapter of the Email Security — Server User Guide.
Note
You can use a regular expression within the sender IP address. Use a backslash (\) to escape special regular expression characters.
