我尝试过这么多不同的教程试图让它工作但无济于事。这是我使用的代码，目前它的工作方式非常完美，除非我嵌入图像。嵌入图像后，就不会收到电子邮件。

发送电子邮件非常复杂，所以我建议您使用经过测试的库，而不是直接使用PHP的mail()函数。
某些邮件服务使用非常旧的软件。他们可能会拒绝包含超过70个字符行的电子邮件（我已经看到过这种情况）或拒绝包含ASCII以外字符的电子邮件。这只是冰山的顶端，所以很难说你的具体信息有什么问题。
如果您要编写自己的邮件实现，首先应阅读一些相关的RFC，如PHP手册中提到的那些：
以下RFC可能有用：»RFC 1896，»RFC 2045，»RFC 2046， »RFC 2047，»RFC 2048，»RFC 2049和»RFC 2822。
或者您可以使用Zend\Mail，PEAR::Mail，SwiftMailer或PHPMailer等库，并依赖这些软件包的开发人员进行的测试。
