"unable to send mail" messages, how to remove????

I inadvertently ran a cron job that contained a line to send email. This was before I had the time to set up email. Now I keep getting mails from the Mail Daemon saying that my message could not be delivered, will keep retrying for 5 days.

How can I purge this reoccuring message (cleanly)? It’s driving me nuts!


Use postqueue -p to show the mail, postsuper -d <ref_num> to remove or postfix -f to flush them all… or postsuper -d deferred.

That should be postqueue -f and not postfix -f
