我将安然电子邮件数据集作为一个文件夹，其中包含文本文件形式的电子邮件，我想提取这些电子邮件的“正文”部分
问题是，发件人的电子邮件、收件人的电子邮件等字段由 To:、From: 等指定。但 Body 不以任何标题开头，它只是在指定所有其他字段后才开始。
现在，一个文本文件可以包含许多正文（在电子邮件线程/对话的情况下）。我想从这些文件中提取正文。可以使用javamail api，如果可以，那么如何使用？它只是离线数据集，在我的硬盘驱动器中以文本文件的形式，而不是在互联网上。
文件是这样的——

Heather,
This is exactly what we need. Would it possible to add the prior day for each of the dates below to the pivot table. In order to validate the curve shift on the dates below we also need the prior days ending positions.
Thank you,
Phillip Allen
