Cisco Cisco Email Security Appliance C160 Mode D'Emploi

Use Global Unsubscribe to ensure that specific recipients, recipient domains, or IP addresses never 
receive messages from the Cisco appliance. If Global Unsubscribe is enabled, the system will check all 
recipient addresses against a list of “globally unsubscribed” users, domains, email addresses, and IP 
Addresses. Matching emails are not sent.

For more information, see “Using Global Unsubscribe” in the “Configuring Routing and Delivery 
Features” chapter of the Cisco IronPort AsyncOS for Email Advanced Configuration Guide.

You use the Network > Bounce Profiles page (or the 

bounceconfig

 command) to configure how Cisco 

AsyncOS handles hard and soft conversational bounces for each listener you create. You create bounce 
profiles and then apply profiles to each listener using the Network > Listeners page (or the 

listenerconfig

 command). You can also assign bounce profiles to specific messages using message 

filters.

For more information about bounce profiles, see “Directing Bounced Email” in the “Configuring 
Routing and Delivery Features” chapter of the Cisco IronPort AsyncOS for Email Advanced 
Configuration Guide.
