What are the basic components required to create a DMARC record?
To create a DMARC record, you publish a DNS TXT record at _dmarc.yourdomain.com containing at least v=DMARC1 (this must be first) and p=(none|quarantine|reject), and you typically add optional tags like rua, ruf, pct, adkim, aspf, sp, fo, and ri to control reporting, alignment, rollout, and subdomain behavior. DMARC (Domain-based Message Authentication, Reporting, and Conformance) tells…

DMARC (Domain-based Message Authentication, Reporting, and…
