I'm pretty sure that the horse is well into the glue stage, but just in case... Making modifications to basic, underlying specifications, is a difficult and potentially dangerous game. One could argue either way about the multi-valued From:, but at least it has an essential relationship to DMARC, since DMARC evaluates From:. If DMARC were required to handle multi-valued From:, it would alter DMARC noticeable, as was evident in the debate about this issue. The MX requirement has no such linkage. d/ -- Dave Crocker Brandenburg InternetWorking bbiw.net _______________________________________________ dmarc mailing list [email protected] https://www.ietf.org/mailman/listinfo/dmarc
