No. All of the complications in mailing lists arise from the fact that the author of the message is not related to the operator of the list. Even though ESPs are generally sending mail on behalf of customers, their relationship to the customers allows them to be the customer, as far as mail authentication is concerned. There are some issues about how a customer delegates part of its identity to its ESP, but they are completely, totally, unrelated to the MLM issues we've been arguing about.
