When you create a new listener via the System Setup Wizard, AsyncOS creates 
the listener with default values. However, when you create a listener manually, 
AsyncOS does not use these default SBRS values.

Use the Listeners page (Network > Listeners) or the 

listenerconfig

 command 

to configure listeners that run over available IP interfaces on the Cisco IronPort 
appliance. For more information about creating and configuring listeners, see the 
“Customizing Listeners” chapter in the Cisco IronPort AsyncOS for Email 
Advanced Configuration Guide. In “Using Virtual Gateway™ Technology” in the 
Cisco IronPort AsyncOS for Email Advanced Configuration Guide, the Cisco 
IronPort Virtual Gateway technology is explained, in which you can further 
define and group IP interfaces over one or many IP addresses, or groups of IP 
addresses.

In this configuration, the Enterprise Gateway configuration accepts email from 
the Internet and relays email to groupware servers, POP/IMAP servers, or other 
MTAs. At the same time, the enterprise gateway accepts SMTP messages from 
groupware servers and other email servers for relay to recipients on the Internet.
