How to catch bounced messages

Hi,

We are creating a free web based mail system. We are using a dedicated server for the same.

Currently i am finding that when a message is sent to a unknown email address which does not exists like say abcd@987yhjsyshs.com

The mail does not bounce back. How do i make sure that the mail bounces back How to catch bounced messages This is important or otherwise our users will think that the message has gone through.

Do we need to configure something on the server.

Please help.
