I think I'll stick with the "in layman terms" part of the message
because that's most clearly stated:

In layman terms:
What if my SMTP mail server detects a non-DK/IIM ready message?
IMO, it will be a very long time (if ever) before a "typical" mail
server will be able to take some action such as rejecting a message
based on a missing signature, except possibly when the originating
domain advertises that it signs all of its mail.
You need to answer that question otherwise what is the use of using DK/IIM
if a system still needs to work and be ready for non-DK/IIM messages?
It's another message classification criterion, and when present enables
reputation and accreditation based on who the signer is.
Now of course, it might work well in an exclusive CISCO corporate/enterprise
settings, a big pat on the back, an exciting marketing and promotion largely
based on "hope" I can imagine for your big customer base. But this is not
a standard across the board.
I hope it's obvious that's not Cisco's intent. But it should be
possible with standards-based message authentication for anyone to more
accurately whitelist their suppliers, customers, and partners, to make
sure that their messages never get lost.
