Retrieving the header field from bounced mail

I am sending email with some custom value set in the email header from my application. When the email get bounced back I am not able to get the custom value from the bounced mail.

I think the SMTP server remove the header before it send the bounce message to the sender.

Is there any way to get the original header( set with custom value) from the bounced mail?
