DMARC checker
Read the DMARC policy at _dmarc.
The lookup goes from your browser straight to a public service. We never see the domain.
What this checks
DMARC is a DNS record at _dmarc.<domain> that tells receivers what to do with mail that fails SPF or DKIM, and where to send reports about it. This tool reads that record and lists its tags in plain English.
What to look for
The p tag is the policy: none only watches, quarantine sends failing mail to spam, and reject blocks it outright. A new domain usually starts at none to collect reports, then moves up once the reports show real mail is passing.
rua is where the daily summary reports go. Without it, nobody is watching who sends mail as this domain.
A missing record is not neutral
With no DMARC record, receivers fall back to their own judgment about spoofed mail from this domain, which is usually more permissive than any policy the owner would choose.
