True, but the system in charge of delivering the email to your mailbox,
does not know about this trust. So how can we infer you have given this
trust to the mailing list? Is your trust the same as some other person?
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?
Generally not, I don't think, though MUAs do.
2) do we need a mechanism to alert the receiving MTA that you have
subscribed to a mailing list, and all messages should pass through?
Quite possibly, but that's really not DKIM related at all, more of an MUA
design decision.
Cheers,
Steve
