One of the things that's stuck with me since we were working on what became RFC 4871 is the notion that you only really know anything when DKIM succeeds. (But then, of course, you need to be cautious about over-interpreting exactly what it's telling you.) You can't conclude anything from a failure because there are so many legitimate failure modes. -MSK
