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 none named
  • 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.
