    # Parameter file for sendmail (sourced by /usr/share/sendmail/sendmail)
    # Make all changes herein, instead of altering /etc/init.d/sendmail.
    #
    # After making changes here, you'll need to run /usr/sbin/sendmailconfig
    # or /usr/share/sendmail/update_conf to have the changes take effect -
    # If you change DAEMON_MODE, QUEUE_MODE, or QUEUE_INTERVAL, you'll also
    # need to run /etc/init.d/sendmail restart.
    #
    # Changes made herein will be kept across upgrades - except for comments!
    # Some comment lines have special significance ...
    #
    # **** **** **** **** DO NOT EDIT THE COMMENTS **** **** **** ****
    #
    # Supported parameters (and defaults) are listed herein.
    #
    # Notes:
    # * This setup allows sendmail to run in several modes:
    # - listener and queue runner..DAEMON_MODE="daemon".QUEUE_MODE="daemon"
    # - listener only..............DAEMON_MODE="daemon".QUEUE_MODE="none"
    # - queue runner only..........DAEMON_MODE="none"...QUEUE_MODE="daemon"
    # - *NOTHING* ?!?..............DAEMON_MODE="none"...QUEUE_MODE="none"
    #
    # * You can also run the listener from inetd:
    # - listener and queue runner..DAEMON_MODE="inetd"..QUEUE_MODE="daemon"
    # - listener only..............DAEMON_MODE="inetd"..QUEUE_MODE="none"
    #
    # * You can also run the queue runner from cron:
    # - listener and queue runner..DAEMON_MODE="....."..QUEUE_MODE="cron"
    # - queue runner only..........DAEMON_MODE="none"...QUEUE_MODE="cron"
    #
    # * _PARMS entries herein are shown in precedence order, any later _PARMS
    # field will, if applicable, override any previous _PARMS fields.
    #
    # * Values *MUST* be surrounded with double quotes ("), single quotes
    # will *NOT* work !

    # Queue Aging Configuration
    #
    # Why would you want to age your queues? On every queue-run interval,
    # sendmail will try *every* file in the queue... If a site is down
    # for a while, considerable time can be wasted each interval in retrying
    # it. The scheme supported allows aging by time, and can move the older
    # files to another (less frequently run queue), thereby reducing overal
    # system impact - and providing better mail throughput.
    #
    # Note that this support is completely separate from QUEUE_MODE=cron,
    # you can age queues even if you're running QUEUE_MODE=daemon.
    #
    # There are four parts to the queue aging support, and these parts
    # may be repeated, to operate on multiple queues.
    #
    # 1. Interval at which to age the queues (in minutes).
    # What interval should you use? Roughly twice the normal queue
    # interval, so that messages are tried twice in each successively
    # slower queue.
    #
    # NOTE: some values just wont work, due to crontab pecularities
    # a value of 90 minutes will actually be run at every x:30 !
    # Please check /etc/cron.d/sendmail to make sure it is doing what
    # you thought it should !
    #
    # 2. Criteria (optional and defaults to interval). This is the
    # specification of which files to move. It defaults moving
    # files whose age in the queues exceeds the interval.
    # This field, if specified can be very complex - supporting
    # aging by just about anything! see qtool(8) for details.
    #
    # 3. To queue. This is the queue to which files will be moved.
    # It may be fully qualified, or relative to /var/spool/mqueue.
    #
    # 4. From queue. This is the queue from which files will be moved.
    # It may be fully qualified, or relative to /var/spool/mqueue.
    #
    # Samples:
    # AGE_DATA="[['25m', '', 'hourly', 'main']]";
    # Every 25 minutes, move any file older than 25 minutes from
    # /var/spool/mqueue/main to /var/spool/mqueue/hourly
    #
    # AGE_DATA="[['25m', '', 'hourly', 'main'],\
    # ['120m', '', 'daily', 'hourly']]";
    # Same as the above, but also move files from the hourly queue
    # to the daily queue after 120 minutes in the hourly queue.
    #
    # AGE_DATA="[['25m',\
    # '-e \'$msg{message}[0] == /Deferred: 452 4.2.2 Over quota/\'',\
    # 'overquota', 'main']]";
    # Every 25 minutes, move all files deferred because of quota
    # violations from /var/spool/mqueue/main to
    # /var/spool/mqueue/overquota where they can be processed on
    # a different interval, or by some other means.
    #
    # If the above samples suggest Perl arrays, well, they are...
