LDAP Database Setup

An LDAP database may be used to store mail account information. LDAP is useful for consolidating mail server account information with an existing account database that handles mail or other applications.

The mail server may be setup to use LDAP account information locally or for remote account verification. See External LDAP Database for more complete information about LDAP database support and data formats.

LDAP Account Database

When LDAP is configured as the account database, the mail server uses LDAP to access account information for all local domains. The database may be populated with extensive account data, including anti-spam filter information.

LDAP for Remote Verification

When LDAP is configured as the remote verification database, the mail server uses LDAP to acces account information for relayed domains. This improves message filtering since the mail server can reject messages for invalid accounts.
