Server mx-corp3.cbn.net.id [210.210.188.92] tidak mendukung BATV sehingga terjadi seperti itu.
Sender Null Return Path (< >) umumnya adalah DSN/Bounce atau Autoresponder message atau Return Receipt notification atau Read Receipt notification.
Kalau mau terima message itu dari MX backup, maka masukkan sender host/IP kedalam backscatter exempt list.
