Still (in case your words imply something else) i find it very much beneficial if it is not only OpenPGP / S/MIME which can be used to verify the message that is then distributed by the mailing-list, as a new message. If i as a ML reader get "this" through the today practically omnipresent DKIM automatically, where "this" is the cryptographical security that the message *really* came from the domain it is supposed to come from. Then this is good, despite what RFC 5321bis says on end-to-end security. And i do not even need to trust the ML system, i can verify the original message. |Not surprisingly, I refer to RFC 5598 about such things, since the IETF |email community spent 5 years developing it.
