2. Requirements

Cette page resume la section correspondante du RFC 9989 et conserve les tags DMARC, noms DNS, ABNF et valeurs IANA.

The requirements cover high-level goals, anti-phishing utility, scalability, and out-of-scope items. DMARC is intended to scale to Internet mail, work with existing DNS and email authentication infrastructure, and help Mail Receivers make handling decisions when domain use fails validation.

The mechanism does not solve all phishing or display-name abuse, and it does not authenticate message content itself.
