We are running into trouble with signing our outgoing mailings with DKIM using opendkim as a filter for Postfix.

我们在使用opendkim作为Postfix的过滤器时，与DKIM签署了我们的发送邮件，这让我们陷入了麻烦。

This issue only occurs when sending HTML emails from phpList. All other text mailings and mailings from other services sign correctly and verify. phpList uses phpMailer as the engine.

这个问题只发生在从phpList发送HTML邮件时。其他服务的其他文本邮件和邮件正确无误并进行验证。phpList使用phpMailer作为引擎。

If we send the mailing as "text", then we have no problem. If we send the mailing as "HTML" then body hash fails.

如果我们将邮件发送为“文本”，那么我们就没有问题了。如果我们将邮件发送为“HTML”，那么body哈希就失败了。

This problem existed in v2, however we used to force phpList to ONLY send as HTML.

这个问题存在于v2中，但是我们使用了强制phpList作为HTML发送。

This error occurs when sending the message as a joint HTML and TEXT email (which is the default in v3).

当将消息作为一个联合HTML和文本电子邮件发送(这是v3中的缺省值)时，就会出现此错误。

I presume it's something to do with line breaks/returns.

我想这与换行/退货有关。

Can somebody point us in the right direction?

有人能指出正确的方向吗?

Thanks for your help in advance.

谢谢你的帮助。

I ran into the exact problem you are describing where [PlainText DKIM=pass] and [HTMLBody DKIM=fail] when sending to Gmail. I'm using C# MailMessage and by default the body default character set is "us-ascii", which works fine for Text based emails, but not HTML ones. Default character set for Email Subject is UTF-8, so no need to set again.

在发送到Gmail时，我遇到了您描述的确切问题(明文DKIM=pass)和[HTMLBody DKIM=fail]。我使用的是c# MailMessage，默认情况下，body默认字符集是“us-ascii”，它适用于基于文本的电子邮件，而不是HTML格式的邮件。邮件主题的默认字符集是UTF-8，所以不需要再设置。

When sending a HTML Email, you have to code the following parameter before sending:

在发送HTML邮件时，您必须在发送之前编码以下参数:

Mailmessage.BodyEncoding = Encoding.UTF8;

After making this small change, Gmail registers my emails again and I receive a DKIM=pass; when I view the original source. Also these are the relevant headers

在做了这个小小的改变之后，Gmail再次注册了我的邮件，我收到了一个DKIM=pass;当我看到原始的源。这些也是相关的标题。

MIME-Version: 1.0
Content-Type: text/html; charset=utf-8
Content-Transfer-Encoding: base64
*followed by block of base64 body text*

Perhaps you can mimic the behavior using PHP, and maybe change yours from

也许您可以使用PHP模拟该行为，并可能更改您的行为。
