- RFC7960 - Interoperability Issues between Domain-based Message Authentication, Reporting, and Conformance (DMARC) and Indirect Email Flows
- Domain-based Message Authentication, Reporting, and Conformance (DMARC) introduces a mechanism for expressing domain-level policies and preferences for email message validation, disposition, and reporting. However, the DMARC mechanism enables potentially disruptive interoperability issues when messages do not flow directly from the author's administrative domain to the final Recipients. Collectively, these email flows are referred to as "indirect email flows". This document describes these interoperability issues and presents possible methods for addressing them.
- RFC8601 - Message Header Field for Indicating Message Authentication Status
- This document specifies a message header field called "Authentication-Results" for use with electronic mail messages to indicate the results of message authentication efforts. Any receiver-side software, such as mail filters or Mail User Agents (MUAs), can use this header field to relay that information in a convenient and meaningful way to users or to make sorting and filtering decisions.
- This document obsoletes RFC 7601.
- RFC8616 - Email Authentication for Internationalized Mail
- 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.
- RFC8617 - The Authenticated Received Chain (ARC) Protocol
- The Authenticated Received Chain (ARC) protocol provides an authenticated "chain of custody" for a message, allowing each entity that handles the message to see what entities handled it before and what the message's authentication assessment was at each step in the handling.
- ARC allows Internet Mail Handlers to attach assertions of message authentication assessment to individual messages. As messages traverse ARC-enabled Internet Mail Handlers, additional ARC assertions can be attached to messages to form ordered sets of ARC assertions that represent the authentication assessment at each step of the message-handling paths.
- ARC-enabled Internet Mail Handlers can process sets of ARC assertions to inform message disposition decisions, identify Internet Mail Handlers that might break existing authentication mechanisms, and convey original authentication assessments across trust boundaries.
- RFC9091 - Experimental Domain-Based Message Authentication, Reporting, and Conformance (DMARC) Extension for Public Suffix Domains
- Domain-based Message Authentication, Reporting, and Conformance (DMARC), defined in RFC 7489, permits a domain-controlling organization to express domain-level policies and preferences for message validation, disposition, and reporting, which a mail-receiving organization can use to improve mail handling.
- DMARC distinguishes the portion of a name that is a Public Suffix Domain (PSD), below which Organizational Domain names are created. The basic DMARC capability allows Organizational Domains to specify policies that apply to their subdomains, but it does not give that capability to PSDs. This document describes an extension to DMARC to fully enable DMARC functionality for PSDs.
- Some implementations of DMARC consider a PSD to be ineligible for DMARC enforcement. This specification addresses that case.
