Remarks

A reply that names the wrong ancestors is not a message with a cosmetic defect. Every mail client threads from In-Reply-To and References and from nothing else, so a guessed value puts the reply in a conversation of its own in every recipient's mailbox, and no later correction reaches the copies already delivered. This deployment pays that cost twice: its own threads are assembled from the same three identifiers, so a reply whose headers are wrong comes back from Sent as a conversation of one here as well.

The placement is derived from what the original message carried rather than supplied by whoever authored the answer. That is what makes it correct by construction: an authoring boundary names the stored email it is answering, and the identifiers come out of that message's own headers.

Fields

The greatest number of ancestors a composed message writes into References.

Properties

InReplyTo

None

Gets the placement of a message that answers nothing, which writes neither header.

References

Gets the path back to the root of the conversation, in header order, with the answered message last.
