Do not do that. Failed DKIM is the same as no DKIM at all (by RFC) and
here is a lot reasons why legitimate email can have broken DKIM
signature. By my experiences, all SPAM has either valid or no
signature...
If you really want that, do it on per domain base. Create DB of "must
pass" domains and reject those only, but once again, prone to false
positives...
