Postfix with LDAP backend
Although there is a lot of documentation regarding Postfix and OpenLDAP I could not find a complete example. A good starting point when looking for the integration is the LDAP_README of postfix which gives at least some basic information. In this post I'll show how I managed to combine Postfix with OpenLDAP. I had the following requirements for my setups: Host multiple Domains Each user can have one or more addresses, not limited to a single Domain Each user does only have one Login and Mailbox.
