Ooh, DKIM vs. list managers again. I don't think that anyone other than the management of ietf.org gets to decide what their signing policy is. There are zillions of ways that mailing lists decide what gets posted to a list. If you like their list management policy, you can trust their signatures. If you don't, you don't.
