This is currently the top google hit for ‘flush postfix’. Congrats!
Unfortunately the command listed under the ‘Flush All Emails’ header actually deletes all emails. The correct command is ‘postfix flush’.
you should differ between flush and delete
Send immediately with Flush
postqueue -f
Delete mail
postfix -d
My Nagios server gone mad and sends thousands of emails. Thanks you for your tutorial. Only 300 approx emails in my inbox and I flushed remaining in queue.
Thanks – I had two bounce messages stuck in the queue that I’ve now deleted
postuser is not a command.
Thanks for pointing out. I have corrected command. It’s postsuper.
Thanks, it worked for me.
