The OP mentioned starting with a queue file, and using "postcat -ebh"
to extract its content. With a queue file in hand, one can copy it
into the "hold" queue (owner:group "postfix:postfix", mode 0700) and
then (assuming nothing else is on "hold"):
# postfix stop
# postsuper -s
# postfix start
# postsuper -H ALL
If there multiple messages on hold, release just the desired one with:
# postqueue -j |
jq 'select(.sender == "j...@example.org") | .queue_id)' |
postsuper -H -
Adjust the jq "select" condition as appropriate. Releasing a queue
file from hold does not modify its content.
