Free DMARC lookup

Look up the DMARC policy at _dmarc and read what receivers should do when SPF or DKIM fails.

Where the record lives

DMARC is a TXT record on _dmarc.example.com, not on the apex. p=none means “collect reports only”. p=quarantine sends failures toward spam. p=reject tells receivers to refuse them. rua is the mailbox that receives aggregate reports.

Alignment

DMARC passes when either SPF or DKIM passes and the domain aligns with the From header. A passing SPF on a different envelope domain still fails DMARC.
