Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

This chapter explains the features that affect routing and delivery of email traveling through the Cisco 
IronPort appliance. After you have configured the gateway to receive email with listeners, you can 
further tailor the configuration of the routing and delivery that the appliance performs, for both inbound 
(receiving email from the Internet) and outbound (sending email from your internal systems) processing.

In 

 you customized private and public listeners to service SMTP 

connections for an Enterprise Gateway configuration. Those listeners were customized to handle specific 
connections (via HAT modification) and receive mail for specific domains (via RAT modification of 
public listeners). 

The Cisco IronPort appliance routes mail to local domains to hosts specified via the Network > SMTP 
Routes page (or the 

smtproutes

 command). This feature is similar to the sendmail 

mailertable

 feature.

If you have completed the GUI’s System Setup Wizard (or the Command Line Interface 

systemsetup

 

command) as described in the “Setup and Installation” chapter of the Cisco IronPort AsyncOS for Email 
Configuration Guide and committed the changes, you defined the first SMTP route entries on the 
appliance for each RAT entry you entered at that time.
