Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

Generally, the masquerading feature rewrites the Envelope Sender, and any 
subsequent actions to be performed on the message will be “triggered” from the 
masqueraded address. However, when you run the 

altscrchost

 command from 

the CLI, the altsrchost mappings are triggered from the original address (and not 
the modified, masqueraded address).

For more information, see 

 and 

. 

You configure the static masquerading table of mappings by using the 

edit -> 

masquerade

 subcommand of the 

listenerconfig

 command. Alternatively, you 

can import a file containing the mappings. See 

. The subcommand creates and maintains a table that maps input 

addresses, usernames, and domains to new addresses and domains. See 

 for more information on LDAP masquerading queries. 

When messages are injected into the system, the table is consulted, and the 
message is rewritten if a match in the header is found. 

A domain masquerading table is constructed as follows:

The following table lists valid entries in the masquerading table:

a list of one or more 
usernames and/or domains to 
match 

whitespace (space 
or tab character)

the rewritten username 
and/or domain

username@domain

This entry specifies a username to match. Incoming email messages matching a 
username on the left-hand side are matched and rewritten with the address on the 
right-hand size. The right-hand side must be a full address. 

username@domain
