You'd accept the message?

That depends on what I think of dkim.mit.edu. If they had a history of sending good mail, sure. If not, probably not.

It's probably worth reminding people yet again that the point of DKIM is to reliably tie a message to a domain, so you can use that domain's reputation to evaluate the mail. SSP doesn't change that.

This example also reminds us that unrelated to SSP, real world filtering can make good use of other sorts of info like realistic (i.e., not self-published) estimates of how likely various domains are to be phish targets.

R's,
