Microsoft Defender for Email & Collaboration - "Whitelist"
We have "Whitelisted" some domains (e.g. appriver.com) by adding the domain to "Add trusted senders and domains" in the Spam policies; as well as adding a rule in Microsoft365 Exchange Mail flow Rule...
- I do see SFV:BLK in the header.

For the policy, the domains are in Allowed Domains list; the e-mail addresses are also in Allowed Senders list; which is redundant I think. When one didn't work, I added the other. I think either the issue is somewhere else, or I am not understanding where to make the change (Defender Portal -> Email & Collaboration -> Policies & Rules -> Threat Policies -> Anti-Spam Policies -> Anti-Spam inbound policy)

Ensure that in all policies you have the Sender is not in blocked senders and domains.
For example, when you open Anti-Spam policy and scroll down, you will see there "Allowed and blocked senders and domains" -> Blocked senders / Blocked domains.
In addition to that, check if you have Preset policies. You can try to exclude the sender there as well.
