+
+postfix_mailqueue - Plugin to monitor postfix mail spools
+
+=head1 ABOUT
+
+A guide to postfix mail queue manageent can be found at
+L<http://www.postfix.org/QSHAPE_README.html#queues>
+
+A summary:
+
+=over 4
+
+=item maildrop
+
+Messages that have been submitted via the Postfix sendmail(1) command,
+but not yet brought into the main Postfix queue by the pickup(8)
+service.
+
+=item hold
+
+Messages placed in the "hold" queue stay there until the administrator
+intervenes
+
+=item incoming
+
+Inbound mail from the network, or mail picked up by the local
+pickup(8) daemon from the maildrop directory.
+
+=item active
+
+Messages that the queue manager has opened for delivery. Only a limited number
+of messages is allowed to enter the active queue (leaky bucket strategy, for a
+fixed delivery rate).
+
+=item deferred
+
+Mail that could not be delivered upon the first attempt. The queue manager
+implements exponential backoff by doubling the time between delivery attempts.
+
+=item corrupt
+
+Unreadable or damaged queue files are moved here for inspection.
+

+
+=head1 CONFIGURATION
+
+By default "postconf -h queue_directory" is used to determine the
+spool directory.  Is postconf is not available in the $PATH then
+/var/spool/postfix is assumed.  This can be overridden by the
+"spooldir" environment variable like so:
+
+ [postfix_mailqueue]
+    env.spooldir /var/spool/postfix
