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.
