电子邮件头字段'thread-index'如何工作？ [英] How does the email header field 'thread-index' work?

问题描述

我想知道有没有人知道电子邮件标题中的线程索引字段是如何工作的？

I was wondering if anyone knew how the thread-index field in email headers work?

这是一个简单的电子邮件线索索引，

Here's a simple chain of emails thread indexes that I messaged myself with.

Email 1 Thread-Index: AcqvbpKt7QRrdlwaRBKmERImIT9IDg==
Email 2 Thread-Index: AcqvbpjOf+21hsPgR4qZeVu9O988Eg==
Email 3 Thread-Index: Acqvbp3C811djHLbQ9eTGDmyBL925w==
Email 4 Thread-Index: AcqvbqMuifoc5OztR7ei1BLNqFSVvw==
Email 5 Thread-Index: AcqvbqfdWWuz4UwLS7arQJX7/XeUvg==

我似乎无法确定地说出如何将这些电子邮件链接在一起。通常，我将使用回复到字段或引用字段，但我最近发现黑莓不包括这些字段。唯一的包括Thread-Index字段。

I can't seem to say with certainty how I can link these emails together. Normally, I would use the in-reply-to field or references field, but I recently found that Blackberrys do NOT include these fields. The only include Thread-Index field.

推荐答案

有一个很好的分析，这个非标准的Thread-Index href =http://blog.postmaster.gr/2007/12/11/trying-to-make-use-of-outlooks-thread-index-header/ =noreferrer>这篇文章以及其中的链接，包括此pdf （CEAS 2006年会议上提交的论文）和<一个href =http://blog.postmaster.gr/2007/12/23/more-fun-with-message-threading/ =noreferrer>这个后续，其中包括一个评论来自 evolution 源代码的问题（似乎反映了这个无证标题的大量逆向工程）。

There's a good analysis of how exactly this non-standard "Thread-Index" header appears to be used, in this post and links therefrom, including this pdf (a paper presented at the CEAS 2006 conference) and this follow-up, which includes a comment on the issue from the evolution source code (which seems to reflect substantial reverse-engineering of this undocumented header).

执行摘要：本质上，作者最终放弃使用这个标题，并推荐并显示一种不同的方法，这也是在 c-client 库中实现的， UW IMAP工具包开源包（这不是仅适用于IMAP - 不要让这个名字愚弄你，它也适用于POP ，NNTP，本地邮箱& c）。

Executive summary: essentially, the author eventually gives up on using this header and recommends and shows a different approach, which is also implemented in the c-client library, part of the UW IMAP Toolkit open source package (which is not for IMAP only -- don't let the name fool you, it also works for POP, NNTP, local mailboxes, &c).
