I noticed new field "DMARC" in the "Show original" message overview and caused for the message with valid DKIM and SPF to be delivered to Spam. No such field exist in the interface for older messages, so this is something fresh.
After creating default _dmarc TXT record (with p=none currently), it was fixed.
Anyone heard something? Thank you.
EDIT: Based on older messages, that field was added 1 of May.
This overview also shows other requirements you may have missed: https://www.proofpoint.com/us/blog/email-and-cloud-threats/g...
As for DMARC in the headers, I'm pretty sure Google has done that for years when DMARC is being checked (i.e. when it's being offered by the sending domain).
(and yes, this was supposed to be enforced last year)
Google does have newish (early 2024) policy regarding messages purporting to be from domains which lack a DMARC policy statement. But this is about mail delivery, not the Show Original UI feature. It’s possible they have been only slowly ramping up implementation or perhaps your domain was previously under the threshold but is now over.
