Question

所以我一直在努力解决这个问题已经有一段时间了，并最终得到了一些工作。在某些电子邮件客户端上，这段代码显示正确嵌入的三个图像，一些将它们作为附件附加，而其他图像则不显示它们。我做错了什么以及如何解决它。

电子邮件是使用php的mail()发送的 - 功能如下：mail($_POST['email'],'Signature',$body,$header);

此外，在任何人拍摄之前，我知道这不是正确的编程习惯，但是这个脚本是一个本地脚本，只有我们才能访问简单生成的电子邮件签名。这就是为什么它根本没有进行任何输入验证或清理。

$header = 'From:webmaster@nobelis.co.za' . "\r\n";
            $header .= 'MIME-Version: 1.0' . "\r\n";
            $header .= 'Content-type:multipart/mixed; boundary="B_3504178637_3566343"' . "\r\n";
            $body = '> This message is in MIME format. Since your mail reader does not understand
this format, some or all of this message may not be legible.

--B_3504178637_3566343
Content-type: multipart/alternative;
    boundary="B_3504178637_3589184"
