IP ini IP apa ya pak ? bukannya IP mail saya 117.102.88.187 ?
PTR record memang standard penulisannya begitu :-)

$ host 117.102.88.187
Host 187.88.102.117.in-addr.arpa. not found: 3(NXDOMAIN)

dan saya cek PTR rec utk pttdp.com adalah MX-corp.cbn.net.id
MX-corp.cbn.net.id adalah MX record bukan PTR record.

Jika di biznet di ganti/tambah PTR menjadi webmail.pttdp.com,
Jangan minta ke biznet (ISP) tetapi mintakan ke DNS hoster (CBNnet)
untuk membuatkan CNAME record (host aliases)

webmail.pttdp.com       CNAME   pttdp.com

penambahan CNAME atau A record tidak mengubah alur email, hanya MX
record yang akan mempengaruhi aliran email dari Internet ke MDaemon.


Tapi di email pertama Bp disebutkan :

minta ke ISP (Biznet) dibuatkan PTR record di reverse DNS zone

187.88.102.117.in-addr.arpa.    PTR     pttdp.com

Makanya saya mau mintanya ke Biznet, jadi PTR harus saya minta kemana ya ?

Thanks
