You then enable this query on a listener so that when a message is received by the listener, the group 
query is triggered.

To skip virus and spam filtering for members of the IT group, you create the following message filter to 
check incoming messages against LDAP groups. 

The rcpt-to-group in this message filter reflects the DN entered as the group name: cn=IT, ou=groups, 
o=sample.com. Verify that you use the correct group name in the message filter to ensure that your filter 
matches the name in your LDAP directory.

Messages accepted by the listener trigger a query to the LDAP server to determine group membership. 
If the message recipient is a member of the IT group, the message filter skips both virus and spam 
checking and delivers the message to the recipient. To enable the filter to check the results of the LDAP 
query, you must create the LDAP query on the LDAP server and enable the LDAP query on a listener. 

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 “MyCompany” purchases company “HisCompany” and company 
“HerCompany” MyCompany maintains its domain, MyCompany.example.com as well as domains for 
HisCompany.example.com and HerCompany.example.com, and it maintains a different LDAP server for 
employees associated with each domain. To accept mail for all three of these domains, MyCompany
