经过进一步的调查，三星邮件应用程序似乎对纯文本和 HTML 部分进行了编码，每个部分都用 base64 编码。我发现如果在两者之间添加一个空行，邮件过滤器就能正常工作。可能是三星没有添加它应该添加的空行，或者邮件过滤器未能正确找到纯文本/HTML 文本部分，并且没有意识到一旦找到 HTML 部分，它就知道该部分的标题在哪里结束以及消息内容从哪里开始。
我制作了一个我认为可以说明问题的示例电子邮件。如果您查看 HTML 部分，它会回复之前的消息。导入器似乎无法看到原始消息是从哪里开始的。

Yes and we are getting lots in ABC and urgent care, along with vaccination side effects from flu + booster. Apparently DEF111 can't deal with this sort of query. Looking good for Xmas and NY week 2222
