You don't have to read all my posts... :-) Also, my perspective is not from "one particular MTA", rather it is a perspective based on a decade and half of building usable SMTP transport security, which is a diverse mixture of opportunistic and mandatory TLS, and interacts in interesting ways with DNS. The converse viewpoint is that for too long Internet security has been too narrowly driven solely by HTTPS. Perhaps it is time to consider additional perspectives (though of course not only such perspectives). There is a large majority of folks in all the various WGs who are not working on SMTP let alone Postfix. I don't think there's a serious risk of hyper-focus. -- Viktor.
