电子邮件标题字段“线程索引"如何工作? [英] How does the email header field 'thread-index' work?

问题描述

我想知道是否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?

这是我给自己发送消息的一个简单的电子邮件线程索引链.

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==

我似乎无法确定如何将这些电子邮件链接在一起.通常，我会使用回复字段或参考字段，但我最近发现黑莓不包括这些字段.唯一包含 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

它们是 base64 编码的对话索引值.无需对它们进行逆向工程，因为它们已由 Microsoft 记录在例如http://msdn.microsoft.com/en-us/library/ms528174(v=exchg.10).aspx 和更详细的http://msdn.microsoft.com/en-us/library/ee202481(v=exchg.80).aspx

They are base64 encoded Conversation Index values. No need to reverse engineer them as they are documented by Microsoft on e.g. http://msdn.microsoft.com/en-us/library/ms528174(v=exchg.10).aspx and more detailed on http://msdn.microsoft.com/en-us/library/ee202481(v=exchg.80).aspx

您示例中的索引似乎并不代表相同的对话，这可能意味着发送邮件的软件无法将它们链接在一起.

Seemingly the indexes in your example doesn't represent the same conversation, which probably means that the software that sent the mails wasn't able to link them together.

不幸的是，我没有足够的声誉来添加评论，但 adamo 是正确的，它包含一个时间戳 - 一个有点深奥的编码部分 FILETIME.但它也包含一个 GUID，因此几乎可以保证该邮件是唯一的(当然，同一邮件可以存在多个副本).

Unfortunately I don't have enough reputation to add a comment, but adamo is right that it contains a timestamp - a somewhat esoteric encoded partial FILETIME. But it also contains a GUID, so it is pretty much guarenteed to be unique for that mail (of course the same mail can exist in multiple copies).
