You haven't included the relevant part of the bounce message, i.e. the
headers from the message that was bounced. However, more than likely, the
spammer used your address as his MAIL FROM when he sent the spam message.
If so, it would show up as the Return-Path in the headers of the bounced
spam. The Return-Path is where bounces are sent, which is why you're
getting them. The SMTP protocol, having been designed in the more
happy-go-lucky pre-spam days of the internet, allows the sender to claim
any identity he wants in his MAIL FROM, so it is very easy to forge with
impunity.

You can't.
