p=
The requested handling for mail that fails DMARC: none, quarantine, or reject. None is useful for observation but does not request blocking.

DMARC Checker
Look up a domain’s DMARC policy and review the published record.
Understand the lookup
What this checker is really showing
DMARC tells receiving mail systems what a domain owner wants done when a message claiming that domain fails aligned SPF and DKIM checks. This lookup reads the TXT record at _dmarc.your-domain; it does not inspect a particular message.
Illustrative DNS record
_dmarc.example.com TXT "v=DMARC1; p=none; rua=mailto:reports@example.com"A useful way to check
- 1Enter the domain people see in your From address, without _dmarc.
- 2Check the published policy and any reporting address in the returned TXT value.
- 3Compare the policy with real sending traffic before tightening enforcement.
Read the result
Details worth noticing
rua=
An optional destination for aggregate feedback. A published address does not guarantee that every receiver sends reports.
adkim= / aspf=
Optional alignment settings. Relaxed and strict modes change how closely the authenticated domain must match the visible From domain.
Before you change a record
- A policy alone cannot prove that your legitimate messages pass alignment.
- Two DMARC records at the same name can make policy discovery fail.
- Move to quarantine or reject only after you understand every service sending for the domain.
Quick answers
Does p=none mean DMARC is broken?
No. It requests monitoring rather than enforcement. It is often a useful stage while you review legitimate senders and aggregate reports.
Will this checker tell me whether a message passed DMARC?
No. A message-level result requires its actual headers and SPF/DKIM outcomes. This tool only shows the domain’s published policy.
