Non-authoritative answer:

Kloxo-MR 7 paling update.

Yang sudah coba saya lakukan...
- cek telnet port 25 - 587 = OK
- fixmail-all
- fix-all
- reinstall qmail
- cleanup

Saya juga cek IP di tidak terkena blacklist di situs-situs seperti https://www.spamhaus.org/ dll. IP statusnya hijau yang artinya tidak kena blacklist.

Kira-kira bagaimana solusinya ya?

Coba reboot.

[jamalrahmat]

Barusan saya coba reboot Pak. Hasilnya tetap tidak bisa. Malahan beberapa webmail tidak bisa login. Padahal mau pakai Rainloop.

Rainloop = Tidak bisa login. statusnya... "DOMAIN NOT ALLOWED".
Afterlogic = Login bisa. Kirim pesan ada status error.
Roundcube = Login bisa. Kirim pesan bisa tapi tidak terkirim. Stuck di mail queue.

Sisanya tidak saya coba.

Saya baca-baca ini...

https://forum.mratwork.com/kloxo-mr-tips-and-tricks/(tip)-how-to-setup-qmail-on-kloxo-mr/

Dan saya coba jalankan:
- '/var/qmail/supervise/imap4/run',
- '/var/qmail/supervise/imap4-ssl/run',
- '/var/qmail/supervise/pop3/run',
- '/var/qmail/supervise/pop3-ssl/run',
- '/var/qmail/supervise/smtp/run',
- '/var/qmail/supervise/submission/run'

Malah error Pak...

tcpserver: fatal: unable to bind: address already used'

Sudah saya coba...
- qmailctl stop
- qmailctl start
- fixmail-all
- fix-all
- restart-all

Periksa IP anda melalui mxtoolbox.com.

Yang jelas ada 'Your IP address is listed in the RBL at bogons.cymru.com' dan 'Your IP address is listed in the RBL at bl.spamcop.net'

Sudah saya cek Pak. IP nggak masalah, tidak masuk blacklist...

Code: [Select]

Checking 36.67.23.xxx against 95 known blacklists...
Listed 0 times with 1 timeouts

Nah ada yang aneh ternyata di output telnetnya Pak...

telnet mail.domain.id 25

Code: [Select]

Trying 36.67.23.xxx...
telnet: connect to address 36.67.23.xxx: Connection refused

telnet localhost 25

Code: [Select]

Trying ::1...
Connected to localhost.
Escape character is '^]'.
220 neo.domain.id ESMTP OpenSMTPD

Nah anehnya pas cek localhost yang keluar malah nama hostnya Pak. Biasanya kan yang keluar seharusnya mail.domain.id
