DMARC checker

Look up a domain's DMARC policy and report address.

What the DMARC checker shows

The result reads the TXT record at _dmarc.domain and highlights the p= policy and rua= aggregate report destination.

How to read the policy

p=none monitors mail, p=quarantine asks receivers to treat failures suspiciously, and p=reject asks them to reject failing mail.

Common questions

Should I start with p=reject?

Usually not. Start with p=none, review reports, fix legitimate senders, then move gradually to quarantine or reject.

Does DMARC replace SPF or DKIM?

No. DMARC uses SPF and DKIM results and checks whether at least one passing identity aligns with the visible From domain.
