What we noticed

  • No DKIM selector answered, so the mail of the domain carries no signature.
Senders it names Microsoft 365
  • Microsoft 365 include:spf.protection.outlook.com
  • Microsoft 365 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.
