You should not want to send bounce on "unknown user" error. You have to
check if the user exists in acl_smtp_rcpt ACL, and if the user does not exist,
you should reject the message. In case of sending bounces your server may be
used by spammers to send bounces to any address they want. You'll just get
many abuses on that.
