Cisco Cisco Email Security Appliance C160 Mode D'Emploi

For more information, see “SMTP Address Parsing Options” in the “Customizing 
Listeners” chapter of the Cisco IronPort AsyncOS for Email Advanced 
Configuration Guide.

Outgoing mail is tagged with a special key, and so if that mail is sent back as a 
bounce, the tag is recognized and the mail is delivered. For more information, see 
“IronPort Bounce Verification” in the “Configuring Routing and Delivery 
Features” chapter of the Cisco IronPort AsyncOS for Email Advanced 
Configuration Guide.

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. For example, joe@old.com -> joe@new.com

For more information, see “The Domain Map Feature” in the “Configuring 
Routing and Delivery Features” chapter of the Cisco IronPort AsyncOS for Email 
Advanced Configuration Guide.

For inbound email only, the RAT allows you to specify a list of all local domains 
for which the Cisco IronPort appliance will accept mail.

Alias tables provide a mechanism to redirect messages to one or more recipients. 
Aliases are stored in a mapping table. When the envelope recipient (also known 
as the Envelope To, or 

RCPT TO

) of an email matches an alias as defined in an alias 

table, the envelope recipient address of the email will be rewritten.
