- sam_lowry_ 2mo agoI can't share all of it, but to understand the relationship between SPF, DKIM and DMARC one should know that DMARC covers two possible cases. Either DKIM domain must match From: domain or MAIL FROM domain must match the From: domain plus the IP address of the sender should pass the SPF check https://mikhailian.mova.org/delivering-mails/1.png https://mikhailian.mova.org/delivering-mails/1.png shows the SMTP plaintext chat for the first case, https://mikhailian.mova.org/delivering-mails/2.png https://mikhailian.mova.org/delivering-mails/2.png shows the second.
