Apparently SpamAssassin did not see any DKIM signature in the
mail header section, let alone finding a valid one, otherwise
you'd see rules DKIM_SIGNED and DKIM_VALID rules hitting too.

Have you by any chance set score for these two rules to zero?
Is the Authentication-Results inserted by the same amavisd/SA
pair as the X-Spam-Status, or is there any other processing
going on inbetwen?

The DKIM_ADSP_* rules only hit in the absence of a DKIM_VALID.
