There's a difference between "claims to be from an MLM" and "From an MLM". Today there isn't much value in making the claim, so no one bothers. It would be unfortunate if we recommended something that caused List-ID headers to be less useful because people found value in spoofing them. > And in any event, even if your assertion were true, so what?

"Oooh, it came from a mailing list so I don't care" isn't the most likely response. Which is why the whole straw poll is irrelevant. Since the D in DKIM is Domain, it's really no concern how individuals filter mail.
