Defender Tenant allow/block list

Question

Hi&nbsp;Could someone please she some light on the questions below. Thank you!I need to fully understand what exactly the Tenant Allow/Block lists does is for the two features below.&nbsp;My understanding.&nbsp;domains and addresses are basically, domains I have manually tagged as allowed or block in the quarantine page.Spoofed servers: allow external senders to send as your domain. But why not just add them to the SPF record.

I thought SPF, DKIM, DMARC little bit different at Email security Domain level but you can manage in Azure and Exchange Online environment:&nbsp;

Lots of support for DKIM within Exchange Online but M365 Family users with personalised email addresses still cannot enable it.
