Mail server domain kaha.com [209.95.59.216, slmp-550-127.slc.westdc.net alias mp.kaha.com] tidak punya DNS PTR record sehingga ditolak oleh server gmail.com. Umumnya hal ini terjadi kalau traffic mail dari server mp.kaha.com ke gmail.com tinggi, sudah melewati basic rate limit domain gmail.com.

Disamping itu, server slmp-550-127.slc.westdc.net tidak mendukung SPF Forwarding sehingga tolakkan mail saat forward dikembalikan ke original sender lina.si...@kahatex-ind.com.

Sarankan agar recipient ha...@kaha.com menon aktifkan mail forwarding di mail hosternya. Pilihan lain, pindahkan mail domain kaha.com ke MDaemon server mail.kahatex-ind.com (catatan: MDaemon mendukung multi domain run in single IP atau multi IP).
