电子邮件中的不同内容类型 [英] Different Content Types in email

问题描述

我正在查看发送给我的一些电子邮件的来源，发现其中一个部分的内容类型不同于HTML部分-见下文.

I was reviewing the source of some emails sent to me and noticed in one that the content type for the text part is different from the HTML part - see below.

--_----------=_MCPart_1153762294
Content-Type: text/plain; charset="us-ascii";

--_----------=_MCPart_1153762294
Content-Type: text/html; charset="utf-8"
Content-Transfer-Encoding: quoted-printable

我想知道是否可以这样做?该电子邮件是通过MailChimp服务器从Monkey Wrench发送的.

I was wondering if this is okay to have this? The email was sent from Monkey Wrench via MailChimp server.

推荐答案

要完全回答您的问题，有必要查看完整的标题和正文，但是鉴于我们拥有的内容:是的，可以做到这一点.消息本身可能是multipart，这些是消息正文中两个部分的摘要.

Seeing the complete headers and body would be necessary to fully answer your question, but given what we have: Yes, it's okay to have this. Presumably the message itself is multipart, and these are snippets from two of the parts in the message body.

这是我无耻地偷走的更完整的消息(来自:发送使用"mutt" 的HTML页面作为电子邮件.它包含了您提到的所有部分，如果过于简单的话，它是完全合法的:

Here's a more complete message that I shamelessly stole (from: Send Html page As Email using "mutt"). It includes all the parts you mention, and it is perfectly legit if somewhat simplistic:

Subject: test html mail
From: [e-mail]
To: [e-mail]
Content-Type: multipart/alternative; boundary=bcaec520ea5d6918e204a8cea3b4

--bcaec520ea5d6918e204a8cea3b4
Content-Type: text/plain; charset=ISO-8859-1

*hi!*

--bcaec520ea5d6918e204a8cea3b4
Content-Type: text/html; charset=ISO-8859-1
Content-Transfer-Encoding: quoted-printable

<p><b>hi!</b></p>

--bcaec520ea5d6918e204a8cea3b4--
