Руководство Пользователя для Cisco Cisco Email Security Appliance C170

This chapter guides you through the process of configuring your Cisco IronPort C- or X-Series appliance 
for email delivery using the System Setup Wizard. If you are configuring an Cisco IronPort M-Series 
appliance, please see 

When you have completed this chapter, the Cisco IronPort appliance will be able to send SMTP email 
over the Internet or within your network. 

To configure your system as an Enterprise Gateway (accepting email from the Internet), complete this 
chapter first, and then see 

 for more information.

 

You can install your Cisco IronPort appliance into your existing network infrastructure in several ways. 
This section addresses several options available to you as you plan your installation. 

Please note that your Cisco IronPort appliance is designed to serve as your SMTP gateway, also known 
as a mail exchanger or “MX.” In addition to the “hardened” operating system dedicated for Internet 
messaging, many of the newest features in the AsyncOS operating system function optimally when the 
appliance is situated at the first machine with an IP address that is directly accessible to the Internet (that 
is, it is an external IP address) for sending and receiving email. For example: 

The per-recipient reputation filtering, anti-spam, anti-virus, and Virus Outbreak Filter features (see 

, 

, 

, and 

) are designed to work with a direct flow of 

messages from the Internet and from your internal network. You can configure the Cisco IronPort 
appliance for policy enforcement (

) for all email traffic to and from your enterprise.
