[Smcwg-public] SMCWG: CAA background info

[Stephen Davidson]

Hello all:



As discussed on the call today, in 2023 we will discuss the use of CAA for S/MIME.  Here are some background materials:



*       Proposed CAA text for S/MIME BR at https://github.com/srdavidson/smime/blob/CAA/SBR.md
*       Internet-draft: Certification Authority Authorization (CAA) Processing for Email Addresses https://datatracker.ietf.org/doc/draft-bonnell-caa-issuemail/
*       Discussion of the Internet-draft - if you think CAA is useful for S/MIME please add your voice https://mailarchive.ietf.org/arch/msg/spasm/chcrIZEit6HcdGyFGNzyiL7Dg6k/



CAA is well understood by CAs that issue TLS.  We'd welcome feedback from Certificate Issuers that do not already implement CAA.



Best regards, Stephen
