Checking DMARC policy...
DMARC (Domain-based Message Authentication, Reporting, and Conformance) is a TXT record at _dmarc.<domain> that tells receivers what to do when SPF or DKIM checks fail and where to send aggregate reports.
No DMARC record at this domain
Mail from this domain is not DMARC-protected. Receivers have no policy instruction for handling SPF/DKIM failures.
The policy values p=none / p=quarantine / p=reject move from observation to enforcement. p=none reports issues without acting; p=quarantine routes failing mail to spam; p=reject blocks it outright. The pct= modifier scales enforcement (start at low pct=, ramp up).
Start with p=none + a working rua= reporting address to gather data without disrupting mail flow. Once reports show clean SPF + DKIM alignment for legitimate senders, ramp pct from 25 to 100 under p=quarantine, then promote to p=reject. Without a reporting address, DMARC enforcement is blind.
