I think several of us thought it was in there, but on review it apparently was indeed lost somewhere along the way. We've certainly, as I understand it, been proceeding from that assumption for a very long time. I like the idea of saying so explicitly in 4871bis, and applying it both to signers and to verifiers. I don't like the idea of being any more specific than that. That is, I don't want to create specific text for specific cases we know about because that means anything we don't list could be perceived as less critical. A blanket admonishment to implementers is sufficient and appropriate. _______________________________________________ NOTE WELL: This list operates according to http://mipassoc.org/dkim/ietf-list-rules.html
