Yes. And that the obverse is possible: "I didn't handle this mail". As Jon Callas is fond of saying, you know a protocol is a success when it's abused in ways you never thought possible. The bi-laterals that others have discussed are a small example of this. Jon got it right: we don't need to know all of what is possible with so general a component as DKIM. My personal motivation, going back some seven years now, was about tools for putting credibility (back) into the email system. Clearly this is far from the only motivation across the population of DKIM developers. Varying motives don't necessarily mean varying tools.
