Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

Content dictionaries, disclaimers, and notification templates must be created 
before they can be referenced by content filters. For more information, see 

Two policy tables are defined in the Email Security Manager: one table for 
messages from sending hosts that are stipulated by HAT policies with the 
“Accept” behavior, the other table for sending hosts qualified as having HAT 
“Relay” behavior. The former table is the incoming policy table, the latter is the 
outgoing policy table. 

Incoming messages are messages received from connections that match an 
ACCEPT HAT policy in any listener. 

Outgoing messages are messages from connections that match a RELAY HAT 
policy in any listener. This includes any connection that was authenticated 
with SMTP AUTH.

In certain installations, “internal” mail being routed through the IronPort 
appliance will be considered outgoing, even if all the recipients are addressed to 
internal addresses. For example, by default for IronPort C10/100 customers, the 
system setup wizard will configure only one physical Ethernet port with one 
listener for receiving inbound email and relaying outbound email. 

For many configurations, you can think of the incoming table as Public, while the 
Outgoing table is Private, although both could be used by a single listener. The 
policy table used on a particular message is not dependant on the direction of the 
message, with respect to sender or recipient addresses, out to the internet or in to 
an intranet.

You manage these tables using the Mail Policies > Incoming Mail Policies or 
Outgoing Mail Policies pages in the GUI, or the 

policyconfig

 command in the 

CLI.
