Periksa screening log tanggal 6 Mer 2026 atau dynamic block List atau
spambot detection (kalau diaktifkan)
Koreksi, masalahnya bukan ditolak, tetapi DNS yang jadi rujukan outbound
sender server gagal resolve domain lampung.ptbmi.com.

sama halnya dengan mail yang ditujukan ke domain @ptbmi.com, gagal
dikirim karena DNS resolver yang digunakan sender server (*.netease.com)
gagal resolve domain ptbmi.com
Untuk domain lampung.ptbmi.com, minta ke DNS hoster dnetsurabaya.id
untuk perbaiki DNS record domain lampung.ptbmi.com
$ host -v -t ns lampung.ptbmi.com
Trying "lampung.ptbmi.com"
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 15246

Sementara untuk domain ptbmi.com sih baik-baik saja.
Besar dugaan mail ke domain @ptbmi.com karena sender server tidak
mendukung smtp pipeling dengan benar, sehingga salah satu recipient
domain gagal di resolve membuat semua mail dianggap gagal resolve.
Di MDaemon juga support SMTP pipelining
https://mdaemon.dutaint.com/mdaemon/26.0.0/default-domain-and-servers_servers.html
By default MDaemon supports the SMTP Service Extension for Command
Pipelining (RFC 2920), which means it will send MAIL, RCPT, and DATA
commands in batches instead of individually, which improves performance
over high latency network links. SMTP pipelining is always used for
inbound connections, and it is enabled by default for outbound
connections. Clear this checkbox if you do not with to use it for
outbound connections.
