Direct LDAP Lookup

The MTA looks up the information directly from the LDAP server. The direct lookup provides a scalable, fast, and configurable relationship between the MTA and the LDAP server. The results of the LDAP queries are cached in the process, with configurable size and time, so performance is tunable. See the Sun Java System Messaging Server 6.3 Administration Guide for more information.
