7.6.3-019 8.0.0-671 8.0.2-000 8.5.0-000 8.5.0-473
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.
