PGP signature
（是的，实际内容有三份副本，空内容和 PGP 签名）
第一个 text/plain 部分由邮件列表软件添加，看起来像这样：
_______________________________________________
tor-relays mailing list -- tor-relays@lists.torproject.org
To unsubscribe send an email to tor-relays-leave@lists.torproject.org
Discourse（实际上是通过 .text_part 的邮件 gem）将其内容识别为：
> puts mail.text_part.to_s
MIME-Version: 1.0
Content-Type: text/plain;
charset=us-ascii
Content-Transfer-Encoding: 7bit
Content-Disposition: inline
Content-ID: <6958bf289b75c_b28a46298091029@forum-01-app.mail>
_______________________________________________
tor-relays mailing list -- tor-relays@lists.torproject.org
To unsubscribe send an email to tor-relays-leave@lists.torproject.org
并将其视为带有省略签名的空白正文。
如果不是邮件列表添加的这个几乎空白的部分，Discourse 会从帖子中提取以下内容：
> We received a court order to preserve the data on the system and were
> forbidden from informing the system owner, which was awkward since
> they had informed the system owner...
他们要求了哪些数据？

他们能拒绝你关闭中继吗？
如果可以，你可以在另一个 IP 上运行一个新的“系统”。

我真的找不出 Discourse 在这里处理邮件有什么问题——如果让我来分配责任，我可能会先从邮件列表软件开始，因为它有效地在开头添加了空白内容。这部分内容放在末尾会更合适，在真实消息 之后。
它本可以与 Mail gem 正常工作，在邮件客户端中看起来也会更好——这是 Thunderbird 中收到的原始邮件的样子：
这是我的“修复”版本（test-fixed.eml.txt (14.3 KB)），将邮件列表签名放在底部而不是顶部：
