डीएमएआरसी रिकॉर्ड बिल्डर

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.
