I am not using VFB anymore but it must be somewhere at its script, buddy. You may make a search for $form_notification_subject term inside your wp directory.

Just add below code after line 2151:

wp_mail( 'your mail address', esc_html( $form_notification_subject ), $message, '', $attachments );

after:
wp_mail( $copy_email, esc_html( $form_notification_subject ), $message, '', $attachments );

It will send a copy of mail to you.

I found a solution but you have to wait for few days till I get back to my pc.
