Working with a postfix mail queue

Some useful commands when working with a postfix mailqueue:

  • “postsuper -r ALL”. Requeues all messages.
  • “postcat [file]”. Views queue files in /var/spool/bla.
  • “postqueue”. Deal with queue.
This one is to remove all messages with a certain recipient:
mailq | tail -n +2 | grep -v '^ *(' | awk  'BEGIN { RS = "" }  { if ($8 == "person@example.com" && $9 == "") print $1 } ' | tr -d '*!' | postsuper -d -

I believe there were more, but I can’t remember them. Wish I had blogged earlier…
