It is, as you say, simple linking. Then I'm somewhat at a loss to understand what you mean by threading. The linking of replies to the messages being replied to joins the entire set together into a thread. The presentation of the thread as a visual hierarchy or whatever is a matter for the MUA. >> > FWIW, I've found that RFC 2822 has a better discussion of the use of > "in-reply-to" and "references" headers and their intended usage. I quoted RFC822 because you said you weren't aware of RFCs which specify threading, and 822 is the original standard reference for email (at least in the form that's still in use). 2822 is certainly more extensive, but I don't think it adds anything to the present discussion. For example, I'm not aware of any mail clients that use the References header, or that allow a message to be in reply to more than one originating message (such clients may of course exist, in which case it would be interesting to know about them). RFCs often specify stuff that most clients don't implement, e.g. not many people know that you can have a mail message with multiple From: headers (the canonical example is a message sent by a committee, each member of which appears in the From: line with their own address). I've never seen such a message and I doubt I could construct one with any of the clients I use, but the RFCs allow it. poc -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
