Adding a Global Unsubscribe Address Using The CLI
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.
@.example.com
Partial Domain
The partial domain syntax is used to block all 
recipients destined for a particular domain and all its 
subdomains.

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.
