Unsubscribe Headers For s2Member Emails

Tomorrow a bunch of providers are going to start enforcing DKIM verification and Unsubscribe headers being mandatory in emails - I’m good with my DKIM verified at Amazon for SES, but I’m unsure if s2Member is adding the required email headers ‘List-Unsubscribe-Post’ and/or ‘List-Unsubscribe’ to all the transactional/notification emails it sends.
