Not receiving bounce back emails on inbox

Hello, I have been testing and i have try to send email to some nonexisting emails and i am facing with a problem. Bonce Back emails are not coming to my inbox, but when i check at CWP Mail Queue
 i can see the bounce back error. How to make it "to receive it on email inbox". Is that any option that needed to change?
As you may i understand i want to use it to clean a email list from bounces!

try checking in the email log what kind of error you get
