Fix "DMARC quarantine / reject": Your mail is being quarantined or rejected by DMARC policy

If your email is bouncing with DMARC quarantine / reject, it means your mail is being quarantined or rejected by DMARC policy. Here is exactly what causes it and how to fix it.

What DMARC quarantine / reject means

When your DMARC policy is p=quarantine or p=reject and a message is not aligned, receivers will spam-folder or bounce it. This usually means SPF or DKIM is not aligned with your visible From domain.

How to fix DMARC quarantine / reject

• Confirm DKIM signs with your From domain and SPF aligns.
• Read DMARC aggregate (rua) reports to find unaligned sources.
• Only move to p=reject after alignment is clean.
