Postfix LDAP Howto

LDAP Support in Postfix

Postfix can use an LDAP directory as a source for any of its lookups: aliases(5), virtual(5), canonical(5), etc. This allows you to keep information for your mail service in a replicated network database with fine-grained access controls. By not storing it locally on the mail server, the administrators can maintain it from anywhere, and the users can control whatever bits of it you think appropriate. You can have multiple mail servers using the same information, without the hassle and delay of having to copy it to each.
