Cisco Cisco Email Security Appliance C160 Mode D'Emploi

Once you create the domain-based query, you need to associate it with a 
public or private listener.

Submit and commit your changes.

A chain query is a series of LDAP queries that the IronPort appliance attempts to 
run in succession. The IronPort appliance attempts to run each query in the 
“chain” until the LDAP server returns a positive response (or the final query in the 
“chain” returns a negative response or fails). Chain queries can be useful if entries 
in your LDAP directory use different attributes to store similar (or the same) 
values. For example, you might have used the attributes 

maillocaladdress

 and 

mail 

to store user email addresses. To ensure that your queries run against both 

these attributes, you can use chain queries. 

To configure chain queries, complete the following steps:

Create server profiles for each of the queries you want to use in the chain queries. 
For each of the server profiles, configure the queries you want to use for a chain 
query. For more information, see 

Create the chain query. For more information, see 

.

Enable the chain query on the public or private listener. For more information 
about configuring listeners, see “Configuring the Gateway to Receive Mail” in the 
Cisco IronPort AsyncOS for Email Configuration Guide.

You can also enable domain-based queries for LDAP end-user access or spam 
notifications for the IronPort Spam Quarantine. For more information, see 
“Configuring the IronPort Spam Quarantines Feature” in the Cisco IronPort 
AsyncOS for Email Daily Management Guide.
