The mailing list needs to build and maintain a good reputation, just the same as any other source of email. That I, the final recipient, trust it and want the mail it sends will help it do that. > > So the receiving MTA, sees messages with List-id: headers in direction to > your mailbox. What it shall do? The Receiving MTA does not usually know > you have subscribed to the mailing list... Nor does it care. If I signed up for a mailing list, I'm going to want to receive email from it. I'm not going to report it as spam, I'm going to go looking for missing mails (especially the initial COI challenge) in my spam folder. All this behaviour will give the mailing list manager a good reputation with my ISP. Similar behaviour by other recipients will also give it a good reputation, all tied to the DKIM d= value. This isn't a special case - it's just incoming email that's coming from a sender with a good reputation, tied to the MLMs d= token. > 1) as Murray says, It can infer it has to deliver (or not) the email based > on other participants reputation to build a list reputation? side note: Eh. If the signature of a particular sender happens to survive, and that sender happens to have a better reputation than that of the list then it might make some difference. It's not something I'd actually try and do, though. > do > mail receivers treat mailing list differently than any other emails?

Quite possibly, but that's really not DKIM related at all, more of an MUA design decision.
