while it is off-topic: The In-Reply-to and References-header are not the same. The in-reply-to-header tells you, for which message a message is a direct reply. The reference-header tells to which emails the mail belongs. Now-adays the reference-header are not very useful anymore, but in the old-times it could happen that a reply reached a third party before the original message reached the third. Example: You have 3 emails. Starter: Message-ID: A Answer: Message-ID: B, In-reply-to: A, References: A Answer-Answer: Message-ID: C, In-reply: B, References: An, B If the answer-answer (C) reaches you before the answer (B), your email-program still knows that it somehow belongs to the starter-eMail (A). When the answer (B) reaches you, your eMail-programm can sort it in the right position, using the in-reply-to-field. Sincerely, DaB. P.S: I learned it the hard way that people that use the reply-button for new emails that not so bad like the smartphone-guys that write an new email for an reply.
