The MLM can't tell the difference between a rejection due to the recipient address being invalid and due to ADSP. Rejecting due to ADSP is probably wrong due to the spec, but sending mail to a list from a domain publishing ADSP discardable is definitely wrong, so apportion the blame as you wish. > John's response seems to imply that it is sender's responsibility not to > send to lists in first place (if they use discardable). But can we be sure > this will happen? Of course not. That's an example of the reason that I don't find ADSP useful (as opposed to manually vetted discard lists.) There's no way to tell whether the party publishing discardable understands what they're saying. > - Wouldn't we have same problem with forwarders? and I don't think sender > can predict whether mail will go thru forwarders.... DKIM is not SPF. It is uncommon for a forwarder to break a DKIM signature. We designed it that way.
