=head1 NAME
postfix_mailqueue_ - Plugin to monitor postfix mail spools per running postfix
=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.
=back
=head1 CONFIGURATION
Uses the last part of the symlink name to get the postfix queue directory for the config file.
It then extract the queue path from the configuration file and uses it as a spooldir.
A environment spooldir can be set as a fallback.
[postfix_mailqueue]
env.spooldir /var/spool/postfix
=head1 AUTHOR
Unknown.
Extended to multiple queue use by Clemens Schwaighofer (gullevek@gullevek.org) in 2010.
