After adding your email server IP/FQDN in email settings you have left some test voicemails but no email arrives!

You check the “qmail.current” log under “View log files” and find the issue, whew. How ever, now you are left with lots of failed voicemail to email messages in the qmail buffer which you dont want to be sent to the users

How do i delete unwanted emails from the qmail queues?
