Why are emails from gmail.com receiving this message and is hotmail.com blocking messages for "safe" senders?

    Any chance sender here is using custom domain, not the free gmail.com domain?

    What exactly does the technical details say? Did it mention SPF, DKIM and DMARC issue?

    If so, we are seeing a lot of these the last few days. Get your SPF, DKIM and DMARC set up on the Google side should fix the issue.
