States what a message said about being sent by a machine rather than written to one person.

public enum EmailAutomation

Fields

AutomaticallySubmitted = 2

The message was submitted automatically rather than by a person composing it.

BulkPrecedence = 3

The message declared itself bulk, list, or junk precedence.

MailingList = 1

The message was distributed by a mailing list, which stamped its own identity onto it.

None = 0

The message claimed nothing, which every ordinary message a person wrote also does.

Remarks

Each value but the first is a claim the sender itself made in a header defined for exactly that purpose, so this is read rather than guessed: a mailing list stamps List-Id (RFC 2919) or the List-* headers RFC 2369 defines, an automatic responder stamps Auto-Submitted (RFC 3834), and bulk mail has stamped Precedence since long before either. A message carrying none of them says nothing, which is None rather than a statement that a person wrote it.

Which of the three a message carried is kept rather than flattened into a flag, because they are different claims and a later reader may want them apart: a list posting is written by a person to many, while an automatic reply is written by nobody at all.
