Ballot Contents

Summary:

After discussions around DNSSEC enforcement 1 2 3 for all Domain Validation methods, and with the WG’s decision that the e-mail Domain Validation methods are scheduled to be deprecated (SC090), in order to reduce complexity and confusion around the way to enforce DNSSEC checks on the various email service agents, an exception to the DNSSEC enforcement is proposed for those methods.

This version (2) fixes an inconsistency issue raised on the SCWG public list.

S/MIME Requirements
v1.0.12 - Ballot SMC014 - Oct 13, 2025

This ballot introduces requirements that a Certificate Issuer MUST deploy DNSSEC validation back to the IANA DNSSEC root trust anchor on all DNS queries associated with CAA record lookups performed by the Primary Network Perspective, effective March 15, 2026. The ballot is intended to maintain consistency in the S/MIME Baseline Requirements with the requirements of Ballot SC-085 which implemented identical requirements in the TLS Baseline Requirements. Note: SC-085 also introduced requirements in TLS Baseline Requirements for the use of DNSSEC in domain control validation. These requirements are automatically adopted in the S/MIME BR by the email domain control methods that include a normative reference to section 3.2.2.4 of the TLS Baseline Requirements. The draft also includes minor corrections to web links in the text. This ballot is proposed by Stephen Davidson (DigiCert) and endorsed by Client Wilson (Apple) and Ashish Dhiman (GlobalSign).
