*note 服务器名称、我的电子邮件地址、IP 已更改。
我通过雷鸟查看了同一条消息（所以它仍然是相同的 Gmail 地址），并且我得到了带有所有这些有趣字符的相同外观的 html。
现在我将其发送到另一个已设置 Exchange 并通过 Outlook 2010 查看的电子邮件地址。
<html>
<head>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

<div>
<h2>TestEmail</h2>
</div>
<div> Mailer Footer</div>
</body>
</html>
为什么在 Outlook 2010 中看起来正常，但在 gmail/thunderbird 中却不然？

我不知道为什么它说text/plain，因为它使用的是html。

*note server names, my email address, ip's been changed.
I viewed the same message through thunderbird(so it still the same gmail address) and I got the same looking html with all those funny characters.
Now I sent it to another email address that is setup with exchange and viewed through outlook 2010.
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body style="font-size: 1em;">
<img src="http://mysite.com/Content/Images/sitelogo.png" alt="mysite Logo" style="width: 231px; height: 63px;" />
<div>
<h2>TestEmail</h2>
</div>
<div> Mailer Footer</div>
</body>
</html>
Why does it look normal in outlook 2010 but not gmail/thunderbird?

I am not sure why it says text/plain since it is using html.

有趣的字符只是电子邮件正文的编码方式，以避免在传输过程中被破坏，正如信封中的
content-transfer-encoding标头所指定的那样。 Outlook 向您显示已解码的邮件源，但仍然是源，而 GMail 和 Thunderbird 则为您提供源的“原始”视图。在这种情况下，使用的编码称为 quoted-printable。The funny characters are just the way the e-mail body is encoded to avoid getting mangled in transport, as the
content-transfer-encodingheader in the envelope specifies. Outlook shows you the decoded message source, but still the source, whereas GMail and Thunderbird give you a "raw" view of the source. In this case, the encoding used is called quoted-printable.
