Description (partial)

Symptom:
ESA doesn't add Authentication-Results header according to RFC5451. 

The current ESA behavior is:
If DKIM verification is enabled, and the message is not DKIM signed, then ESA add 'neutral' in Authentication-Result header. This behavior is incorrect, ESA should add 'none' instead.

Conditions:
DKIM verification is enabled.
