No, it doesn't follow. IETF's job is not to ensure that arbitrary expectations of email senders (or of domains claiming to represent those senders) are met. > The point I am making here is that nothing that the IETF can do will > create a situation where the sender of an email will be able to ensure > that recipients do not filter the email using a particular technology. True. Recipients (or parties claiming to act on their behalf, with or without informed consent of the actual recipients) are already filtering mail using a variety of (usually ill-chosen) technologies. However that doesn't mean that IETF should necessarily endorse, or even document, any of these technologies. Sometimes it's a disservice to the community to document a bad idea. _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
