Dear Pak Syafril, mohon pencerahannya terkait log error di bawah ini

Sender @mdn.ptbmi.com adalah sub domain dari ptbmi.com, dengan demikian
di DMARC harus di daftarkan juga policy untuk subdomainnya.
$ host -t txt _dmarc.ptbmi.com
_dmarc.ptbmi.com descriptive text "v=DMARC1; p=reject; aspf=s;
rua=mailto:[email protected]";
diganti menjadi
_dmarc.ptbmi.com descriptive text "v=DMARC1; p=reject; aspf=s; sp=none
rua=mailto:[email protected]";
Kalau subdomain ingin menerapkan DMARC juga, maka perlu mengaktifkan SPF
record disamping DMARC record.

$ host -t txt mdn.ptbmi.com
mdn.ptbmi.com has no TXT record
