Hello!
Another consideration is that the sender domain might introduce such a
policy *after* some users *have* already subscribed to mailing lists.
Those wouldn't be "caught" by such a mailing list manager. And
unsubscribing them later (instead of rejecting a subscription in the
first place), e.g. by periodically re-checking, or re-checking on mail
submissions, would in my eyes be a surprising effect.
It would be need to be considered nonetheless to be protocol consistent.
For me, it would be an engineering neglect and "malpractice" to begin
to implement DKIM into a MLS ignoring ADSP knowing full well of the
problems associated with ADSP and 3rd party signing systems such as a
MLS. As more and more receivers begin to add DKIM/ADSP support, the
middle ware market can no longer ignore ADSP themselves in their
receiving component as well.
