Bouncing mail back in case of failure delivery

[shara]

Hello there,

i need to send mail to few addresses with me being the sender.In case the addressee is not existing,ishould get the mail bounced back to me.

I used the following function to achieve that

mail($to, $subject, $message, $headers,"-f $from");

I want teh wrong addressee's mail to be bounced back to me but the above function i used is of no avail.

Can anybody please help me with this?

Thanks in advance,
Shara.
