Hello - We are currently managing several domains that are experiencing spoofing attacks, which led us to implement a p=reject policy. We monitor these domains through Uriports, and while all DKIM/SPF validations pass, exceptions arise with emails routed through security providers such as Cloudflare, Proofpoint, Mimecast, Inky, and others.
Is the "reject" disposition simply noise that can be disregarded, with 100% of these emails still being delivered due to the application of the ARC policy? Or do these emails fail to reach their final destination? Any guidance on this would be greatly appreciated!
