Details:

This feature has been postponed. We see lots of cases where configuration of our protection stack has enabled malicious content to be inadvertently delivered to end users. We’re working on a few features that will help address this problem. The second phase of this is blocking domains that fail authentication. The Antispam policy allows administrators to “Allow” domains regardless of the reputation of the domain. We’re changing our policies to not honor Allow rules when the domain fails authentication. This can be resolved by either addressing the authentication concerns with the sender domain, or adding a transport rule to allow the domain.
