Solid base — one policy step remains.
yahoo.com publishes an enforcing DMARC policy, so mail that forges its domain is quarantined or rejected at the recipient.
Your email protection is not fully strict yet: the SPF setup is ending in a permissive mode, which tells receiving mail servers to be less certain about blocking messages that claim to be from your domain. This matters because it makes it easier for attackers to spoof your domain and send fake email that looks like it came from you. The fix is to tighten the SPF policy so only approved senders are allowed, after you’ve confirmed every legitimate sender is included.
