Kalau DNS SPF domain kobexindo.com sudah pakai policy = reject/failed,
maka diharapkan server mail.d2.co.kr akan menolaknya.

$ host -t txt kobexindo.com
kobexindo.com descriptive text "v=spf1 a mx ~all"

Yang benar

kobexindo.com descriptive text "v=spf1 a mx -all"


Tidak semua server mendukung SPF, misalkan saja server-2x yahoo.com
hanya mendukung DKIM (dan DMARC) sehingga pengaktifan DKIM
record/signing perlu juga dilakukan.
