Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

Domain-based queries are LDAP queries grouped by type, associated with a 
domain, and assigned to a particular listener. You might want to use domain-based 
queries if you have different LDAP servers associated with different domains but 
you want to run queries for all your LDAP servers on the same listener. For 
example, the company “Bigfish” purchases company “Redfish” and company 
“Bluefish.” Bigfish maintains its domain, Bigfish.com as well as domains for 
Redfish.com and Bluefish.com, and it maintains a different LDAP server for 
employees associated with each domain. To accept mail for all three of these 
domains, Bigfish creates domain-based queries. This allows Bigfish to accept 
emails for Bigfish.com, Redfish.com, and Bluefish.com on the same listener. 

To configure domain-based queries, complete the following steps:

Create a server profile for each of the domains you want to use in the 
domain-based queries. For each of the server profiles, configure the queries you 
want to use for a domain-based query (acceptance, routing, etc.). For more 
information, see 

.

Create the domain-based query. When you create the domain-based query, you 
select queries from each server profile, and enable the IronPort appliance to 
determine which query to run based on the domain in the Envelope To field. For 
more information about creating the query, see 

Enable the domain-based 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.
