in a good confifguration postfix doesn't _send_. it _rejects_ the transaction. this is like a 404 in http. the bounce is created by the client MTA, not by your postfix. if you really send bounces, then you have a broken configuration and you need to fix it. you need to make sure you didn't break recipient validation. show logs (of bounces sent by postfix) and output of 'postconf -n' for help.
