Want to just get going ?  Try: qmqtool -l



Q. How do I install qmqtool ?
A. vi qmqtool, and ensure the path and syntax to "ps" and "grep" are
	compatible with your operating system (defined at the top)
   cp qmqtool /usr/local/script/
   chmod 0700 /usr/local/script/qmqtool
   chown root /usr/local/script/qmqtool

Q. Why arent messages that I just expired going away ?
A. After expiring, you can force the queue to run by:
   /var/qmail/bin/qmail-tcpok
   svc -a /service/qmail-send/
A. If you have already forced qmail to re-run the queue, you may be
   running into a scenario where qmail-remote is caching an
   unresponsive SMTP server, and messages after the first are kept in
   the queue to be tried later.  There's no solution to this problem,
   besides to simply delete the messages instead of expire.

Q. Do I really have to restart qmail-send after using -d ?
A. You should.  qmail doesnt know you've removed the message from the
   queue, and will keep trying to send it.  Each time it tries, you'll
   see a complaint in your log file.

Q. What is the difference between 'expiring' and 'deleting' messages?
A. qmail remembers what messages are in it's queue.  If you tinker
   with the queue manually (via deleting a message), you will have
   to restart qmail-send.  By simply expiring the message, you trick
   qmail into thinking the message has been in the queue too long
   (about double the queuelifetime), and qmail gracefully removes the
	message for you.

Q. How can I list all messages that have the subject of
   "Free Pupil Enlargment" ?
A. qmqtool -f '^Subject: Free Pupil Enlargment'
   will do a pretty good job; since qmqtool's -f argument searches
   the entire message, this could list an incorrect message if the
   string 'Subject: Free Pupil Enlargment' is found in the body of
   the email and not in the header.

Q. How can I delete all messages with a subject of "Pupil Enlargment"?
A. qmqtool -d -f '^Subject: Pupil Enlargment!'`
   restart qmail-send.

Q. How can I show how many queued messages a host has sent?
A. If you've got a plain-vanilla qmail installation, try: qmqtool -i
   If you've got frontend servers that relay mail to backend servers,
   qmqtool -i -n 2
   You can also try qmqtool -i -V

Q. How can I keep my queue clean of soon-to-be double bounces?
A. Enter the following single line into root's crontab (adjust for
   syntax and path differences, of course):
   17,47 * * * * qmqtool -e -o 2 -f 'invoked for bounce|^Subject: failure notice' >/dev/null 2>&1
   This is not 100% accurate; some legitimate bounce messages will be
   deleted.

Q. How can I delete all messages from my remote and local queue ?
A. qmqtool -d -f .
   restart qmail-send.

Q. How can I delete multiple messages at a time ?
A. qmqtool -d 1234,5678

Q. How can I find out who most of my remotely queued messages are
   destined for?
A. qmqtool -R | awk '/Recipient:/ { print $3 }' | sort | uniq -c | sort -n
   (your awk, sort, and uniq syntax may differ)

Q. How can I list messages with a subject of "Failure Notice" that
   are 18+ hours old ?
A. qmqtool -o 18 -f '^Subject: Failure Notice'

Q. How can I expire messages with a subject of "Failure Notice" that
   are have been queued for 18+ hours ?
A. qmqtool -e -o 18 -f '^Subject: Failure Notice'

Q. How can I do the previous question, but watch as it goes ?
A. use -V: qmqtool -V -e -o 18 -f '^Subject: Failure Notice'

Q. How can I make a list of just queued bounce messages ?
A. qmqtool -f 'invoked for bounce'
   will do a good job.

Q. What is a "LWQ installation" ?
A. I (and the general qmail community) recommend installing qmail as
   per http://www.lifewithqmail.org/

Q. How can I move qmail's queue to a different machine?
A. Use the backup and restore feature:
	1.  On old machine:
	stop qmail-send
   qmqtool -Bb
   cd /var/qmail
   tar -zcvf queue.tgz queue.backup/
	copy or move queue.tgz to the new machine

	2.  On new machine:
	cd /var/qmail
	tar -zxvf queue.tgz
	stop qmail-send
	qmqtool -Br
	start qmail-send

Q. How can I view message number 12345 ?
A. qmqtool -v 12345

Q. How can I view the whole message 12345, instead of the first 100 lines?
A. qmqtool -wv 12345
