Removing failed emails from the que

Hi

I was setting up a automated email script and got it to work. But I have 3 emails in a que some where which keep trying to be delivered. I want to delete them from the mail que because the settings were wrong when I sent them and they will never get delivered. I have looked for some sort of mail que in Tools / Email but cant find it.

Can someone help or guide me in the right direction.

Thank you in advance for your help
