1. OU FIELDS
The final draft version of the 'Baseline Requirements for the Issuance and Management of Publicly-Trusted S/MIME Certificates' (BR S/MIME) requires that certain information be included in the subject:organizationalUnitName field.
This information is not sufficient to be included in SMIME certificates of sponsor-validated and organization-validated types issued by Spanish Qualified Trust Service Providers (QTSP) for Government Entities, which is regulated.
Spanish QTSPs are legally forced to comply with this regulation regarding certificates issued for Government Entities.
The Spanish regulation requires that these certificates must include in an OU field some specific text strings, such as:
- OU = "SELLO ELECTRONICO" (electronic seal)
- OU = "CERTIFICADO ELECTRONICO DE EMPLEADO PUBLICO" (electronic certificate for employees of the public administration)
In addition, according to the Spanish regulation, these certificates may include in OU fields some codes used by the public administrations.
Moreover, S/MIME certificates of sponsor-validated and organization-validated types issued by Spanish QTSP for non-Government Entities usually include in OU fields other specific information (i.e.: Department), that is not contemplated in the Affiliate definition in BR S/MIME. This information is used by certain applications, and also by certificate subscribers and relying parties. Therefore, the lack of this information would create serious problems in certificate usage.
The possibility of including the department in the OU fields for non-Government Entities, but in a more general way, was previously raised on the Smcwg-public mailing list by a GlobalSign representative, Christophe Bonjean. (April 25th : https://lists.cabforum.org/pipermail/smcwg-public/2022-April/000318.html and May 11th https://lists.cabforum.org/pipermail/smcwg-public/2022-May/000338.html )
All these data included in OU fields of SMIME certificates of sponsor-validated and organization-validated types issued by Spanish QTSP are verified by the RAs against supporting documentation, a Reliable Data Source, or Attestation, that is, in the same way that the subject:title shall be verified (BR S/MIME 188.8.131.52)
1. MAXIMUM VALIDITY PERIOD
The final draft version of the 'Baseline Requirements for the Issuance and Management of Publicly-Trusted S/MIME Certificates' (BR S/MIME) requires a maximum validity period of 825 days for Strict and Multipurpose Generations and 1,185 days for Legacy Generations.
The Spanish Law which regulates trust services according to EU eIDAS Regulation allows qualified certificates to have a validity period up to 5 years (1824 days), including SMIME certificates of organization-validated, sponsored-validated and individual-validated types.

Ballot SMC01: Final Guideline for “S/MIME Baseline Requirements”
Purpose of Ballot:
The S/MIME Certificate Working Group was chartered to discuss, adopt, and maintain policies, frameworks, and standards for the issuance and management of Publicly-Trusted S/MIME Certificates. This ballot adopts a new “S/MIME Baseline Requirements” that includes requirements for verification of control over email addresses, identity validation for natural persons and legal entities, key management and certificate lifecycle, certificate profiles for S/MIME Certificates and Issuing CA Certificates, as well as CA operational and audit practices.
An S/MIME Certificate for the purposes of this document can be identified by the existence of an Extended Key Usage (EKU) for id-kp-emailProtection (OID: 184.108.40.206.220.127.116.11.4) and the inclusion of a rfc822Name or an otherName of type id-on-SmtpUTF8Mailbox in the subjectAltName extension in the Certificate.
The following motion has been proposed by Stephen Davidson of DigiCert and endorsed by Martijn Katerbarg of Sectigo and Ben Wilson of Mozilla.
