Dan nampaknya IP 52.101.188.87 masuk dalam daftar DNSBL tersebut.

untuk menanggulanginya pak ?

Minta pengelola sender server melakukan delist dari DNSBL backscatterer.org

http://www.backscatterer.org/index.php?target=test

Kalau di MDaemon yang pakai DNSBL backscatter.org, bisa masukkan sender address/domain kedalam exempt list.

https://mdaemon.dutaint.com/mdaemon/26.0.0/dns-bl_white_list.html

# All local IPs should be part of this file as well as 127.0.0.1.  Also
# include any IP you might find block-listed by mistake or wish to
# always exempt from the DNS-BL lookup process.
#
# You can also list email addresses here and message sent TO those
# addresses will be accepted regardless of DNS-BL results.
#
# You can also list sender addresses here by prefixing the line with
# the word "from" (no quotes) and then messages sent with a MAIL FROM
# value using that address will be allow-listed. This uses the SMTP
# session MAIL FROM value not the message's From: header value.

from *@sender-domain.co.id

Kalau backscatter cara membuat pengecualiannya seperti ini

https://mdaemon.dutaint.com/mdaemon/26.0.0/security--backscatter_protection_dialog.html

klik"exempt list", isikan sender address atau sender domain

domain.co.id

atau

x.x.x.x


# When domain names are specified, for inbound mail, these are matched
# against the results of a PTR lookup on the connecting IP or, if
# available, on the results of an SPF PTR operation so you need to
# enable one or both
# of those features.  When domain names are specified, outbound mail to
# those  domains will not have the return-path signed by Backscatter
# Protection.
#
# Wildcards and CIDR notation are fine here.
#
# Ex: 127.0.0.1 or 192.0.2.0/24 or *.example.com, one entry per line.
