Delete Messages From Queue - WIKI Cautionary Note Warning, deleting messages from the queue can have a negative consequence of your users. You might need to account for the action and/or confirm your deletion was appropriate. Please try to save the postqueue -p information from the various messages prior to deleting them. This will at least you give you he information to later justify your actions on why you delete msg#. Relevant Sections Of Postsuper Man Page By default, postsuper(1) performs the operations requested with the -s and -pcommand-line options on all Postfix queue directories - this includes the incoming,active and deferred directories with mail files and the bounce, defer, trace and flushdirectories with log files.

-d queue_id Delete one message with the named queue ID from the named mail queue(s) (default: hold, incoming, active and deferred). If a queue_id of - is specified, the program reads queue IDs from standard input. For example, to delete all mail with exactly one recipient user@example.com:

mailq | tail +2 | grep -v '^ *(' | awk 'BEGIN { RS = "" } # $7=sender, $8=recipient1, $9=recipient2 { if ($8 == "user@example.com" && $9 == "") print $1 } ' | tr -d '*!' | postsuper -d -

Specify "-d ALL" to remove all messages; for example, specify "-d ALL deferred" to delete all mail in the deferred queue. As a safety measure, the word ALL must be specified in upper case.

Warning: Postfix queue IDs are reused. There is a very small possibility that postsuper deletes the wrong message file when it is executed while the Postfix mail system is delivering mail.

The scenario is as follows: 1) The Postfix queue manager deletes the message that postsuper(1) is asked to delete, because Postfix is finished with the message (it is delivered, or it is returned to the sender). 2) New mail arrives, and the new message is given the same queue ID as the message that postsuper(1) is supposed to delete. The probability for reusing a deleted queue ID is about 1 in 2**15 (the number of different microsecond values that the system clock can distinguish within a second). 3) postsuper(1) deletes the new message, instead of the old message that it should have deleted.

-h queue_id Put mail "on hold" so that no attempt is made to deliver it. Move one message with the named queue ID from the named mail queue(s) (default: incoming, active and deferred) to the hold queue.

If a queue_id of - is specified, the program reads queue IDs from standard input. Specify "-h ALL" to hold all messages; for example, specify "-h ALL deferred" to hold all mail in the deferred queue. As a safety measure, the word ALL must be specified in upper case. Note: while mail is "on hold" it will not expire when its time in the queue exceeds the maximal_queue_lifetime or bounce_queue_lifetime setting. It becomes subject to expiration after it is released from "hold".

-H queue_id Release mail that was put "on hold". Move one message with the named queue ID from the named mail queue(s) (default: hold) to the deferred queue.

If a queue_id of - is specified, the program reads queue IDs from standard input. Note: specify "postsuper -r" to release mail that was kept on hold for a significant fraction of $maximal_queue_lifetime or $bounce_queue_lifetime, or longer.

Specify "-H ALL" to release all mail that is "on hold". As a safety measure, the word ALL must be specified in upper case.
