Jay, Three questions: * Did you review and understand the extensive discussion that has occurred on the ietf-smtp@ietf.org since the beginning of the month or just the (relatively few) comments on this IETF list? * Did you consider the issues associated with the possibility of IETF servers being out of conformance, whether clearly or marginally, with IETF standards and the implications if that were the case? * Is the answer to the question of where the Secretariat will get guidance and instructions on technical issues going forward that it will come from you and your assessments of those issues and community consensus about them? thanks, john --On Tuesday, December 17, 2019 10:46 +1300 Jay Daley <jay@ietf.org> wrote: > Hi > > While there is not unanimous consensus, I think the mood is > clearly to leave this as an operational decision.
