Show the answer and explanation

✓ Correct answer

  • It excludes matching external email using sender-domain metadata, while ordinary email access remains separate

The external-email preview compares sender metadata with accepted domains and excludes matching email from grounding, summarization, and citation. It does not inspect bodies for every injection, revoke ordinary mail access, or govern every externally originated document.
