Cisco Cisco Email Security Appliance C160 Mode D'Emploi

You can configure a “domain map” for listeners. For each listener you configure, you can construct a 
domain map table which rewrites the Envelope Recipient for each recipient in a message that matches a 
domain in the domain map table. This feature is similar to the sendmail “Domain Table” or Postfix 
“Virtual Table” feature. Only the Envelope Recipient is affected; the “To:” headers are not re-written by 
this feature.

Two entries were added to the 
masquerading table for this 
private listener. The first entry 
masks all subdomains of a 
network (e.g. 

exchange.example.com

 is 

rewritten as 

example.com

). The 

second entry rewrites the bare 
address 

joe

 as 

joe@example.com

.
