DMARCbis (draft-ietf-dmarc-dmarcbis-41) is progressing through the IETF standards process and is intended to obsolete RFC 7489. Key updates include record tag clarifications to reduce ambiguity, clearer reporting expectations, and a standardized DNS tree walk for receiver-side policy discovery. Herr characterizes DMARCbis as an evolution rather than a revolution, and addresses misconceptions such as the idea that publishing a DMARC record alone guarantees inbox delivery. Major mailbox providers like Microsoft, Google, and Yahoo have already tightened sender requirements around DMARC, SPF, and DKIM. ## Full article daily.dev links to this article rather than hosting it.
