authpostfix adds every user that log in with the courier imap or pop3 server to a user defined database.
It must be loaded as the last authentication module for both the imap or pop3 server. Refer to the included documentation for more information about it (/usr/share/doc/courier-authpostfix).
Added users are then allowed to relay mail with Postfix until they are removed from the indicated database.
authcleanup is usually run from a cron job and it is used to remove users that logged in more than timeout minutes ago.
The second parameter is used to locate the database that authcleanup has to clean up. If no database is provided, authcleanup will look for an environment variable named LOGINDB. If none can be found, a default is tried.
