I have a dedicated with CentOS.
When someone sends an email and it bounces back, I get the bounced email, how can I stop this, or how do I configure the server to bounce it back from where it was sent.
I am not sure how to do this on other control panels but if you have cPanel... To disable the user "nobody" from sending email what you can do is click on "Tweak Settings" from Server Setup and locate the following check box "Prevent the user 'nobody' from sending out mail to remote addresses" and make sure that it is checked.
I hope that helped

I wouldn't suggest enabling that setting as it will break a ton of forum scripts and will actually create *more* failures.
Try setting the mail to :fail: in tweak settings instead of :blackhole: which is the default.
