Forgive me for a bit of an aside, sortof. A lot of people have long used the Postal Service analogy of being able to supply an arbitrary return address as a justification for doing the same in email (DC I'm looking at you, buddy).
So did anyone catch the news today that UPS.com are planning to verify the return address of a package against your drivers license? And that other "postal" services may soon follow suit? In other words, the days of providing an unauthenticated "author address" may be numbered in the physical world. It's all in the name of security theater of course, but nonetheless, somewhat amusing in the DKIM context.
