# MSP_MAILSTATS="$parm_def{'MSP_MAILSTATS'}";  Boolean	Listener stats
#	This parameter determines whether or not mailer stats are collected

#				Miscellaneous Confguration
#
# MISC_PARMS="$parm_def{'MISC_PARMS'}";  String  miscellaneous parameters
#	Miscellaneous parameters - applied to any sendmail invocation.
#	Any parameters here are also used when run from cron.
#	Applied after {DAEMON,QUEUE}_PARMS, and can therefore override them
#	if need be (in which case why did use them?)
#	Note that CRON_PARMS, if applicable, will override anything

#
CRON_MAILTO="$parameter{'CRON_MAILTO'}";
#
# CRON_PARMS="$parm_def{'CRON_PARMS'}";  String  cron specific parmeters
#	Cron parameters - applied *only* when sendmail queue running is done

#
# HANDS_OFF="$parm_def{'HANDS_OFF'}"; Binary  Do *NOT* touch the configuration
#	Set this *ONLY* if you are going to be fully responsible for the entire
#	setup of sendmail - the directories, permissions, databases, etc.  With
#	this variable set to "Yes", nothing will be done for you during updates.
#
#	In other words, "The blood be upon your hands" if you set this...
#	My ability to help with problems will be greatly reduced !

#------------------------------------------------------------------------------
#				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...
#
# AGE_DATA="$parm_def{'AGE_DATA'}";  Perl array  Queue aging data
