Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

The following example of creating a listener applies to C170 appliances only. 

In this example portion of the 

systemsetup

 command, a listener named MailInterface is configured to 

run on the MailNet IP interface. Then, it is configured to accept all email for the domain 

example.com

. 

An initial SMTP route to the mail exchange 

exchange.example.com

 is configured. Then, the same 

listener is configured to relay all email for all hosts within the domain 

example.com

. (Note the dot at the 

beginning of the entry: 

.example.com

)

Rate limiting is enabled, and the maximum value of 450 recipients per hour from a single host is 
specified for the public listener. 

The value you enter for maximum recipients per hour you are willing to receive from a remote host is a 
completely arbitrary value, one that is usually relative to the size of the enterprise for which you are 
administering email. For example, a sender who sends 200 messages in an hour might be considered a 
“spammer” (sender of unsolicited bulk email), but if you are configuring the appliance to handle all 
email for a 10,000 person company, 200 messages per hour from a remote host may be a reasonable 
value. Conversely, in a 50-person company, someone sending 200 messages in an hour to you may be an
