Gmail menandai pesan email saya sebagai Spam. Pesan lulus SPF dan DKIM, tetapi gagal DMARC. Apakah ada cara agar pesan saya lewat DMARC?
Saya baru-baru ini mendaftar untuk hosting WordPress di Flywheel, yang menggunakan Mandrill untuk email transaksional. Situs saya memiliki beberapa formulir yang mengirim pemberitahuan email ketika dikirimkan.
Saya melampirkan sumber baku pesan sampel:

Masalah ini disebabkan oleh tidak konsistennya jalur balik dan header Dari :.
Return-Path: mandrillapp.com
Dari: @ seeawsf.com
Ref: https://space.dmarcian.com/how-can-spfdkim-pass-and-yet-dmarc-fail/
Jika domainnya berbeda, DAMRC tidak dapat mengautentikasi acara pengirim meskipun SPF dan DKIM diteruskan dan otentikasi akan gagal.
Dalam hal ini, SPF dan DKIM mengautentikasi mandrillapp.com bukan untuk jungkat-jungkit.
Sebagai solusi, Retrun-Path dan Header From diperlukan untuk domain yang sama atau DMARC akan gagal.
