I don't understand this. If lists got a pass, every spam would grow RFC 2369 header fields. No? So ISTM the received chain needs to be authenticated for the recipient to trust any last-hop sender, list or not. > but they don't so it can't. Origin checks are generally very useful and effective in my experience.
