好的，现在我确实有来自 TS 提供商的时间戳。
我应该如何将其放入 mime 消息中以符合标准？ 据我所知，没有邮件程序支持时间戳，这不是问题，因为我将自己处理 mime 消息。
但是我想让它成为标准方式……有什么例子吗？
谢谢。

我认为@Michael 自己的答案就在那里，但有以下警告：
application/timestamp-reply 旨在传输TimeStampResp，该TimeStampResp 可能或可能不包含TimeStampToken，而就当前目的而言，TimeStampToken 始终需要存在。请参阅 RFC 3161，“2.4.2. 响应格式”。application/timestamp-reply 内容类型当前未定义为安全多部分协议。请参阅 RFC 1847，“1. 简介”和 RFC 3161，“3.1. 使用电子邮件的时间戳协议”。由于前面的原因，我建议以下示例结构：
MIME-Version: 1.0
Content-Type: multipart/signed; protocol="application/timestamp-signature"; micalg="sha256"; boundary="{79EAC9E2-BAF9-11CE-8C82-00AA004BA90B}"

在哪里
tst.bin 是 TimeStampToken。application/timestamp-signature 是一种非标准的安全多部分协议。编辑：
似乎有几个标准适合这里：
但我没有时间详细检查它们。

我相信这是合适的格式：

如果我错了，请编辑我。 有没有支持它的电子邮件客户端来验证？
