In fact SMTP does not care which sender address. Here are possible reasons for check failures: DKIM signature domain and sender (Header From) domain do not align DKIM public key record, published in DNS, is incorrect or is not published at all SenderвЂ™s domain DNS zone is unreachable for lookup. Ask the administrator of the server to not modify messages, which can cause DKIM to fail.

check your zone files and see is there spf and dkim added then try to restart bind dns server.3 EMPTY_MESSAGE Message appears to have no textual parts and no Subject: text Note that the 't' (testing) flag in a DKIM key bypasses this behaviour a bad signature that references a testing flag will still be delivered, though the added Authentication-Results field will indicate both the failed result and the test mode so that consumers of the message can take appropriate action.
