Cisco Cisco Email Security Appliance C160 Mode D'Emploi

Masquerading is a feature that rewrites the Envelope Sender (also known as the sender, or 

MAIL FROM

) 

and the To:, From:, and/or CC: headers on email processed by a listener according to a table that you 
construct. A typical example implementation of this feature is “Virtual Domains,” which allows you to 
host multiple domains from a single site. Another typical implementation is “hiding” your network 
infrastructure by “stripping” the subdomains from strings in email headers. The Masquerading feature 
is available for both private and public listeners. 

The Alias Table feature was 
configured to create the following 
aliases: 

admin: 

administrator@example.com

[ example.com ]

customercare: bob@example.com, 

frank@example.com,

sally@example.com

Note that alias tables apply to all 
email traveling through (received by) 
the appliance, from both private and 
public listeners.
