Email Authentication for Internationalized Mail
RFC 8616, “Email Authentication for Internationalized Mail”, is a Proposed Standard document published in June 2019 by J. Levine. It updates RFC 6376, RFC 7208, RFC 7489. The canonical text is published by the RFC Editor.
Abstract
Sender Policy Framework (SPF) (RFC 7208), DomainKeys Identified Mail (DKIM) (RFC 6376), and Domain-based Message Authentication, Reporting, and Conformance (DMARC) (RFC 7489) enable a domain owner to publish email authentication and policy information in the DNS. In internationalized email, domain names can occur both as U-labels and A-labels. This specification updates the SPF, DKIM, and DMARC specifications to clarify which form of internationalized domain names to use in those specifications.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
