Chapter 4      Understanding the Email Pipeline
Domain-Based Routing
Use the Network > SMTP Routes page (or the 
smtproutes
 command) to redirect 
all email for a particular domain to a specific mail exchange (MX) host, without 
rewriting the envelope recipient.
For more information, see “Routing Email for Local Domains” in the 
“Configuring Routing and Delivery Features” chapter of the Cisco IronPort 
AsyncOS for Email Advanced Configuration Guide
.
Global Unsubscribe
Use Global Unsubscribe to ensure that specific recipients, recipient domains, or 
IP addresses never receive messages from the Cisco IronPort 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
.
Bounce Limits
You use the Network > Bounce Profiles page (or the 
bounceconfig
 command) to 
configure how Cisco IronPort 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
