MXtreme integrates with LDAP (Lightweight Directory Access Protocol) directory services such as Active Directory, OpenLDAP, and iPlanet, allowing you to perform the following:
MXtreme can check for the existence of an internal user via LDAP before delivering a message. This feature allows you to reject mail to unknown addresses in relay domains, reducing the number of attempted deliveries of spam messages for non-existent local addresses. This check can be performed directly to an LDAP server or to a cached directory stored locally on MXtreme.
Group/User Imports
An LDAP lookup will determine the group membership of a user when applying policy-based controls. LDAP users can also be imported and mirrored on MXtreme to be used for services such as the Spam Quarantine.
SMTP Relay Authentication
LDAP can be used for authenticating clients for SMTP Relay.
Mail Routing
LDAP can be used to lookup Mail Routes for a domain to deliver mail to its destination server.
Authentication
LDAP can be used for authenticating IMAP access, user mailbox, and WebMail logins.
