ARC turned out to be a failure since it depends on knowing that the system sending
you mail with ARC seals is trustworthy, and that doesn't scale.

The IETF is currently working on a follow-on to DKIM tentatively named DKIM2 that
is intended among other things to do what ARC was supposed to do in a more scalable
and verifiable way.  I hope by the end of the year we can have trial code for
mailing list software to see how it works.  The large mail systems are all involved
in this and are as eager as anyone for it to succeed.
