我遇到了一个问题，即使使用width属性，图像也会以原始大小显示：

图像嵌入phpMailer，因此源可能看起来略有不同，但宽度属性仍将保留。

只有第一个嵌入图片受到影响

我did a testrun with Litmus和所有其他邮件按预期工作。甚至是Apple Mail 5和Apple Mail 6

这是Apple Mail中的错误还是我错过了什么？

您的HTML无效，请使用validation tool修复错误。特别是你的两个div没有关闭，也不会过去。

我自己邮寄了固定版本，并在苹果邮件（版本7）中阅读，没有任何问题，所以这将解决您的问题，或者您需要附加您正在使用的实际PHPmailer代码或其实际生成的HTML。

这是您的XHTML的有效版本：

我意识到这已经有一年了，但在搜索时无法找到解决方案。我们遇到了类似的问题（特别是在Apple Mail 7和8中），并且在img标签上使用内联CSS已经解决了这个问题。

e.g。而不是：

<div>
    <p>Embeded 1</p>
    <img src="embeded400x200.png" alt="" width="200" height="100" />
    <img src="embeded400x200.png" alt="" width="200" height="100" />
    <img src="embeded200x100.png" alt="" width="200" height="100" />
    <img src="embeded200x100.png" alt="" width="200" height="100" />
</div>

使用：

<div>
    <p>Embeded 1</p>
    <img src="embeded400x200.png" alt="" style="width:200px;height:200px" width="200" height="100" />
    <img src="embeded400x200.png" alt="" style="width:200px;height:200px" width="200" height="100" />
    <img src="embeded200x100.png" alt="" style="width:200px;height:200px" width="200" height="100" />
    <img src="embeded200x100.png" alt="" style="width:200px;height:200px" width="200" height="100" />
</div>
