Domains don't subscribe to mailing lists, individual recipients do. The
recipients in a domain may oppose the domain[-administrator]'s decision,
but often lack the power to have it changed. "Failure to quit your job"
cannot reasonably be construed as consent/support in this context.
So this problem is obviously larger than just discardable. This
can happen any time a list member gets a piece of mail that the filter
in the receiving domain finds objectionable for *whatever* reason. So
what we're really talking about is a 5822 problem, not a DKIM/ADSP problem.
So the question is, in my mind, should the receiver just silently discard
it which breaks reliability but allows the MLM to do nothing special, or
should the receiver bounce/5xx it back. To my mind, if the MLM is going to
do something as drastic kick the receiving user, it ought to at least be
open to a 5xx explanation that it's the mail in question that's the problem
instead of blindly giving the user X number of 5xx's before they're declared
a nuisance and kicked.
