DMARC Record Builder
DMARC (Domain-based Message Authentication, Reporting and Conformance) tells receiving mail servers what to do when a message claiming to be from your domain fails SPF or DKIM checks, and where to send reports. Pick a policy and build the _dmarc TXT record — start with p=none to collect data before enforcing.
What is DMARC?
DMARC sits on top of SPF and DKIM and ties both to the domain in the From header. p=none only reports, p=quarantine sends failures to spam and p=reject blocks them. rua is where aggregate XML reports go.
Publish the record at _dmarc.yourdomain.com, watch reports for a few weeks, then tighten the policy.
