Chapter 2 Configuring Routing and Delivery Features
The partial domain syntax is used to block all recipients destined for
a particular domain and all its subdomains.
10.1.28.12 IP address
The IP address syntax is used to block all recipients destined for a
particular IP address. This syntax can be useful if a single IP address
is hosting multiple domains. The syntax consists of a common dotted
octet IP address.
In this example, the address user@example.net is added to the Global Unsubscribe list, and the feature
is configured to hard bounce messages. Messages sent to this address will be bounced; the appliance will
bounce the message immediately prior to delivery.
