Folks,
As long as there is some effort to review what goals are being pursued, with
respect to mailing lists, I'd like to raise an additional question:
For typical, modern mailing lists, a subscriber can choose between delivery of
each message, as posted individually, versus delivery of batches of messages in
a digest.
In the latter case, no one would reasonably expect a DKIM signature from a
first
(author/originator) sequence to survive. Yet there seems to be some strong
expectation that it will or should survive if the recipient happens to choose
delivery on a per-message basis.
What is the security model that makes this expectation of preservation
important
and reasonable, given that it is so easily and whimsically violated by a common
recipient-selectable setting?
