Cisco Cisco Email Security Appliance C190 Guia Do Utilizador

Mark the checkbox for Accept Incoming Mail to configure the interface to accept 
mail. Enter the name of the domain for which to accept mail.

Enter the Destination. This is the SMTP Route or name of the machine(s) where 
you would like to route email for the domains specified.

This is the first SMTP Routes entry. The SMTP Routes table allows you to 
redirect all email for each domain (also known as a Recipient Access Table (RAT) 
entry) you enter to a specific mail exchange (MX) host. In typical installations, 
the SMTP Routes table defines the specific groupware (for example, Microsoft 
Exchange) server or the “next hop” in the email delivery for your infrastructure. 

For example, you can define a route that specifies that mail accepted for the 
domain 

example.com

 and all of its subdomains 

.example.com

 is routed the to the 

groupware server 

exchange.example.com

.

You can enter multiple domains and destinations. Click Add Row to add another 
domain. Click the trash can icon to remove a row.

Configuring SMTP Routes in this step is optional. If no SMTP routes are defined, 
the system will use DNS to lookup and determine the delivery host for the 
incoming mail received by the listener. (See “Routing Email for Local Domains” 
in the Cisco IronPort AsyncOS for Email Advanced Configuration Guide for more 
information.)

You must add at least one domain to the Recipient Access Table. Enter a domain 
—

example.com

, for example. To ensure that mail destined for any subdomain of 

example.net

 will match in the Recipient Access Table, enter 

.example.net

 as 

well as the domain name. For more information, see 

. 

When configuring your interfaces to relay mail, you define the systems allowed 
to relay email through the appliance.

These are entries in the RELAYLIST of the Host Access Table for a listener. See 

 for more information.

Mark the check box for Relay Outgoing Mail to configure the interface to relay 
mail. Enter the hosts that may relay mail through the appliance.
