What we noticed
- The record ends in ?all, which says nothing about a sender that is not listed.
- The DMARC policy only reports. It does not stop mail that fails.
- The SPF record allows a sender that is not listed, so it gives little protection.
Senders it names Google Workspace
- Google Workspace include:_spf.google.com
- Google Workspace runs its mail hosts
These are the services the records name. A record can name a service no longer used, and a sender can sign without being named.
