ah, I thought you were implying that the From domain had to match d=
part. I see that you are not.

It does not /have to/. However, if it does, recipients get the best 
assurance dkim can deliver. Otherwise, unless they have configured 
their trust assessments engines appropriately, the relevant signature 
cannot be used by the recipients.
