Kelihatnya ini koneksi mail firewall antivirus yang berbasis MTA Exim yang sering pakai protocol yang tidak standard Internet Mail (RFC standard). Coba periksa di smtp-in log 2023-03-14 sebelum jam 14:03 server 168.245.118.232 identitas hostnya apa

Identitas hostnya ini pak o1.ptr5115.jurnal.id [168.245.118.232]


dan kirim mail dari sender mana ke recipient mana saja (mungkin lebih dari 101 recipient)

untuk sender-nya bounces+11642051-f070-6211202288=persada...@em2413.talenta.co

dikirimnya memang ke banyak email alias kami pak (SC terlampir)


Jangan pakai trusted host/trusted IP, itu berkaitan dengan "mail relaying" dan bypass antispam/antivirus.

Baik Pak


Kelihatannya SMTP screening diaktifkan ya.
Coba periksa berapa besar nilainya.

Benar Pak, untuk SMTP Screening aktif dan nilainya adalah sbb :

Blok IPs that connect more than 100 times in 3 minutes

Tapi sepertinya mulai jam 17.04 sudah bisa masuk kembali pak.
