Trigger Warning: If you disable security settings just to make things work, this video may not be for you. In other words, you may experience feelings of shame.
A domain registered for ten years with no published mail policy is not dormant — it is exposed. Reputation systems do not distinguish between negligence and compromise. They only see the absence of published policy.
SPF: v=spf1 -all
DMARC: v=DMARC1; p=reject;
MX: 0 .
DMARC: v=DMARC1; p=reject;
MX: 0 .
If a domain sends no mail, publish SPF -all, DMARC reject, and Null MX. Silence is not protection.
