The user authentication is done by Courier Authdaemon. The following diagram shows this process.Anatomy of PostfixComponentsThe following figure shows the main Postfix system components, and the main information flows between them. Yellow ellipsoids are mail programs. Yellow boxes are mail queues or files. Blue boxes are lookup tables.

Programs in the large box run under control by the Postfix resident master daemon. Data in the large box is property of the Postfix mail system.Receiving MailWhen a message enters the Postfix mail system, the first stop is the incoming queue. The figure below shows the main components that are involved with new mail.Mail is posted locally.
