Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

A traditional sendmail 

/etc/mail/genericstable 

file can be imported. To import a 

genericstable

 file, 

first see 

 to ensure that you can access the appliance. 

Place the 

genericstable

 file in the configuration directory, and then use the 

import

 subcommand of the 

masquerade

 subcommand to upload the file. Use the commands in this order: 

listenerconfig

 -> 

edit

 -> listener_number -> 

masquerade

 ->

 import

Alternatively, you can use the 

export

 subcommand to download the existing configuration. A file 

(whose name you specify) will be written to the configuration directory. You can modify this file outside 
of the CLI and then import it again.

When you use the 

import

 subcommand, ensure that the file contains only valid entries. If there is an 

invalid entry (for example, a left-hand side with no right-hand side), the CLI reports syntax errors when 
you import the file. If there is a syntax error during import, no mappings in the entire file are imported. 

Remember to issue the 

commit

 command after you import a 

genericstable

 file so that the configuration 

changes for the listener take effect. 

In this example, the 

masquerade

 subcommand of 

listenerconfig

 is used to construct a domain 

masquerading table for the private listener named “OutboundMail” on the PrivateNet interface. 

First, the option to use LDAP for masquerading is declined. (For information on configuring LDAP 
masquerading queries, see See 

 for more information on LDAP 

masquerading queries.) 

Then, a partial domain notation of 

is mapped to 

 so that any email sent 

from any machine in the subdomain of 

.example.com

 will be mapped to 

example.com

. Then, the 

username 

 is mapped to the domain 

. The domain masquerading table is then 

printed to confirm both entries, and then exported to a file named 

masquerade.txt

. The 

config

 

subcommand is used to disable re-writing addresses in the CC: field, and finally, the changes are 
committed.
