Mail ditolak karena sender IP (103.12.84.170 punya reputasi buruk (bad
IP reputation).

https://support.google.com/mail/answer/6227174


Domain and IP reputation gives a sense of whether the Gmail spam filter
might mark emails from that Domain or IP as spam or not. Keep in mind
that spam filtering is based on thousands of signals, and that Domain &
IP reputation are just two of them.
About reputations

The definition of spam in the section below includes mail detected as
spam by Gmail’s Spam filter, and mail reported by users as Spam.

    Low - Known to send a considerable volume of spam regularly, and
mail from this sender will likely be marked as spam.


kalau memang user banyak terima spam mail dan melakukan autoforward ke
akun di gmail.com set di antispam content filtering

http://mdaemon.dutaint.co.id/mdaemon/18.0/index.html?sf_options.htm

[x] Don't forward spam

pengaktifan PTR record untuk IP 103.12.84.170, SPF record dengan
policy=FAIL (-all) dan DKIM akan menaikkan IP reputation.
