NAT Mail — gisportal.id / 117.102.73.102

Konteks Mailcow: Mailcow/docs/notes/gisportal-id-mail.md

Arsitektur saat ini (2026-07-06)

Internet MX → mail.gisportal.id → 117.102.73.102
                                      │

Yang tidak di MikroTik

Item Lokasi benar
SPF gisportal.id Master Web DNS
DKIM TXT Master Web DNS
Mailbox / transport Mailcow VM

Legacy geonet.co.id

NAT masih ada ke:

  • 10.100.1.76 — mail hosting lama (port 25/143/993/587)
  • 10.100.1.40 — beberapa rule disabled (AD)

Hybrid Mailcow geonet.co.id masih MX cPanel — NAT .99 ke .24 untuk web.

Troubleshooting

Gejala Cek
Mail tidak masuk gisportal NAT .102:25 → .28; firewall filter forward
TLS mail gagal Cert di Mailcow/nginx, bukan di MikroTik
SPF fail DNS registrar, bukan router 
/ip firewall nat print where dst-address=117.102.73.102
