Figure 5-3 Public and Private Listeners for an Enterprise Gateway 5-4 IronPort Email Security appliance Groupware client B Groupware server (Exchange, Domino, Groupwise) A Cisco IronPort AsyncOS 7.6 for Email Configuration Guide Large Small corporations corporations SMTP Firewall POP/IMAP server Internet Chapter 5 Configuring the Gateway to Receive Email POP/IMAP client In Figure 3-3, one public listener (A) and one private listener (B) are configured on the appliance in this Enterprise Gateway configuration. Figure 3-4 further illustrates the differences between the default settings of public and private listeners. A public listener is intended to receive email from the internet. The public listener receives connections from many hosts and directs messages to a limited number of recipients. Conversely, a private listener is intended to receive email from your internal network. The private listener receives connections from a limited (known) number of hosts and directs messages to many recipients. C10/100 customers: By default, the System Setup Wizard walks you through configuring one public listener for both receiving mail from the Internet and for relaying email from your internal network. That is, one listener can perform both functions. Later in the chapter, these differences will be demonstrated in the Host Access Table and Recipient Access Table for each type of listener.

Two listeners are created: a public listener to serve inbound connections on one interface and a private listener to serve outbound connections on a second IP interface. Figure 5-6 illustrates a typical Email Gateway configuration created by the System Setup Wizard (or CLI systemsetup command) on an Cisco IronPort C150/160 appliance. One public listener on a single IP interface is created to serve both inbound and outbound connections. Cisco IronPort AsyncOS 7.6 for Email Configuration Guide 5-5
