I do not seem to be able to use DKIM to for spam
filtering.  I would like to whitelist all validly signed
DKIM from well known domains.

One way of doing this would be for the MTA to insist on
a valid signature when talking to certain well known
MTAs, and then my MUA could whitelist mail sent from
those well known MTAs

In short, I am not able to get any advantage out of
using this protocol, which means that there is no
advantage in sending me signed mail.
