Configures the block policy rule based on the domain of the sender.
The Email Security — Server appliance immediately marks an email for quarantine if it includes the sender domain that you defined. 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 domain. Use a backslash (\) to escape special regular expression characters.
