[NTLK] Receiving NewtonTalk messages... Gmail issue?

[Dennis Swaney]

Interestingly, this was sent to Junk in Mail 11.5. I went to Mail>View>Message>All Headers to see if I could figure out why and found these:

Authentication-Results: ⁨bimi.icloud.com; bimi=skipped reason="insufficient dmarc"⁩

I see the “insufficient dmarc” in the first and the 2 fails in the third and fourth lines so I’m wondering if that was the reason.
