Dear Pak Syafril, Saat ini secara MX Configuration di tempat saya sebagai berikut :
aio.co.id ---> Pref 10 : mail.aio.co.id aio.co.id --> Pref 20 : mx-corp3.cbn.net.id Yang saya heran adalah banyak e-mail yang di lemparkan oleh MX Backup (CBN) ke tempat kami, dan isinya banyak yang terindikasi SPAM. Mestinya MX Backup ini berfungsi jika e-mail Primary down, maka setiap e-mail di tampung dulu ke MX Backup, dan di retry ke MX Primary jika sudah UP. Saya sudah konfirmasi ke pihak ISP (CBN) bahwa mail server kami (mail.aio.co.id) tidak ada Downtime baik secara server maupun koneksi, tetapi kenapa seolah-olah banyak e-mail yang tertuju ke Domain aio.co.id harus masuk dulu ke MX Backup (tidak langsung ke MX Primary). Berikut salah satu logsnya (MX Backup mengirimkan SPAM) : Fri 2020-09-04 00:05:01.583: [242934] Session 242934; child 0002 Fri 2020-09-04 00:05:01.583: [242934] Accepting SMTP connection from 210.210.188.51:36064 to 192.168.1.19:25 Fri 2020-09-04 00:05:01.585: [242934] --> 220 mail.aio.co.id ESMTP Fri, 04 Sep 2020 00:05:01 +0700 Fri 2020-09-04 00:05:01.587: [242934] <-- EHLO mx-corp3.cbn.net.id Fri 2020-09-04 00:05:01.588: [242934] --> 250-mail.aio.co.id Hello mx-corp3.cbn.net.id [210.210.188.51], pleased to meet you Fri 2020-09-04 00:05:01.588: [242934] --> 250-ETRN Fri 2020-09-04 00:05:01.588: [242934] --> 250-AUTH LOGIN CRAM-MD5 PLAIN Fri 2020-09-04 00:05:01.588: [242934] --> 250-8BITMIME Fri 2020-09-04 00:05:01.588: [242934] --> 250-ENHANCEDSTATUSCODES Fri 2020-09-04 00:05:01.588: [242934] --> 250 SIZE 52428800 Fri 2020-09-04 00:05:01.590: [242934] <-- MAIL FROM:<glo...@calorie-perks.com> SIZE=4052 Fri 2020-09-04 00:05:01.591: [242934] --> 250 2.1.0 Sender OK Fri 2020-09-04 00:05:01.593: [242934] <-- RCPT TO:<whiday...@aio.co.id> Fri 2020-09-04 00:05:01.593: [242934] --> 451 4.1.0 Recipient disabled <whiday...@aio.co.id> Fri 2020-09-04 00:05:01.593: [242934] whiday...@aio.co.id account is currently disabled Fri 2020-09-04 00:05:01.595: [242934] <-- QUIT Fri 2020-09-04 00:05:01.595: [242934] --> 221 2.0.0 See ya in cyberspace Fri 2020-09-04 00:05:01.595: [242934] SMTP session terminated (Bytes in/out: 111/346) Fri 2020-09-04 00:05:41.880: [242949] Session 242949; child 0002 Fri 2020-09-04 00:05:41.880: [242949] Accepting SMTP connection from 210.210.188.51:36069 to 192.168.1.19:25 Fri 2020-09-04 00:05:41.882: [242949] --> 220 mail.aio.co.id ESMTP Fri, 04 Sep 2020 00:05:41 +0700 Fri 2020-09-04 00:05:41.885: [242949] <-- EHLO mx-corp3.cbn.net.id Fri 2020-09-04 00:05:41.885: [242949] --> 250-mail.aio.co.id Hello mx-corp3.cbn.net.id [210.210.188.51], pleased to meet you Fri 2020-09-04 00:05:41.885: [242949] --> 250-ETRN Fri 2020-09-04 00:05:41.885: [242949] --> 250-AUTH LOGIN CRAM-MD5 PLAIN Fri 2020-09-04 00:05:41.885: [242949] --> 250-8BITMIME Fri 2020-09-04 00:05:41.885: [242949] --> 250-ENHANCEDSTATUSCODES Fri 2020-09-04 00:05:41.885: [242949] --> 250 SIZE 52428800 Fri 2020-09-04 00:05:41.887: [242949] <-- MAIL FROM:<info...@lembaga-lpkmi.xyz> SIZE=550820 Fri 2020-09-04 00:05:41.890: [242949] --> 250 2.1.0 Sender OK Fri 2020-09-04 00:05:41.892: [242949] <-- RCPT TO:<srhaps...@aio.co.id> Fri 2020-09-04 00:05:41.893: [242949] --> 451 4.1.0 Recipient disabled <srhaps...@aio.co.id> Fri 2020-09-04 00:05:41.893: [242949] srhaps...@aio.co.id account is currently disabled Fri 2020-09-04 00:05:41.894: [242949] <-- QUIT Fri 2020-09-04 00:05:41.894: [242949] --> 221 2.0.0 See ya in cyberspace Fri 2020-09-04 00:05:41.895: [242949] SMTP session terminated (Bytes in/out: 114/346) Fri 2020-09-04 00:05:41.895: ---------- Best Regards, Slamet Raharjo IT Dept. -- --[mdaemon-l]---------------------------------------------------------- Milis ini untuk Diskusi antar pengguna MDaemon Mail Server di Indonesia Netiket: https://wiki.openstack.org/wiki/MailingListEtiquette Arsip: http://mdaemon-l.dutaint.com Dokumentasi : http://mdaemon.dutaint.co.id Berlangganan: Kirim mail ke mdaemon-l-subscr...@dutaint.com Henti Langgan: Kirim mail ke mdaemon-l-unsubscr...@dutaint.com Versi terakhir: MDaemon 20.0.1, SecurityGateway 7.0
