Aligning CSBRs with recent SCWG ballots

Bruce said the ballot is ready to move forward. Corey will propose and Martijn and Bruce will endorse.

Cleanup ballot

Martijn is starting to work on this ballot to clean up effective dates.

Moving towards a single profile

No further discussion; need Microsoft on the call to help establish direction.

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).
