Probably not. Mailing lists sometimes change the message ID, so it's not a very useful indication of evil. Having watched this thread, I don't see what the issue is. If a bad guy rewinds and resends a message, it'll arrive from the bad guy, not from wherever it was supposed to come from. I think we agree that ARC is only useful on messages that come from normally trustworthy sources, which the bad guy would not be. So what problem are we solving here?
