Subject: Re: [ietf-dkim] MLMs and signatures again
If anyone's claiming that contributors' DKIM signatures on list mail are
important, a good start would be to look at how PGP and S/MIME signatures
have been treated during the many years they've been in use. I don't see
any harm in experiments like having an MLM adding a signed A-R header to
the mail, since it doesn't break anything that works now, but I would want
rather concrete evidence from anyone claiming that people pay any more
attention than they do to S/MIME signatures now.
There are parties that want to do that experiment because they see potential in
it. (In fact they're doing it now through a non-standard hack; I need to ask
them for results.) What would probably be helpful is some decent description
from them of why they think it's valuable and how they plan to use it.
You're absolutely right that nobody's cared up until now, but I'm not as sure
as you are that this makes the question utterly uninteresting.
