Cisco Cisco Email Security Appliance C170 사용자 가이드

This section describes Cisco IronPort Virtual Gateway™ technology and its benefits, how to set up a 
Virtual Gateway address, and how to monitor and manage Virtual Gateway addresses.

The Cisco IronPort Virtual Gateway technology allows you to configure enterprise mail gateways for all 
domains you host — with distinct IP addresses, hostname and domains — and create separate corporate 
email policy enforcement and anti-spam strategies for those domains, while hosted within the same 
physical appliance.
