PHP电子邮件脚本仅发送一些消息[重复]

Question

我正在使用来自http://blog.teamtreehouse.com/create-ajax-contact-form 的 php 邮件脚本连接到我正在构建的网站上的联系表单。

我已将所有内容放在一起，并且似乎运行正常（不显示任何错误），但我没有收到大部分电子邮件。如果我使用我的个人电子邮件帐户之一测试联系表，我将收到该消息。如果我使用任何其他电子邮件（例如来自http://www.fakemailgenerator.com 的电子邮件），我将不会收到任何东西。我已经附上了下面的所有代码。有什么我遗漏的东西，任何人都可以发现吗？

如果有帮助，该站点将托管在 AWS LAMP linux 实例中，并且域使用 GoDaddy。

提前致谢。

我认为只是亚马逊过滤了可疑邮件提供商。大多数 SMTP 服务器都带有过滤器。这些过滤器可防止用户接收垃圾邮件。

正如Amazon FAQ 所说：

Amazon SES 使用内部反垃圾邮件/反病毒技术来过滤包含劣质内容的电子邮件并阻止它们被发送。

您的消息格式是错误的，我不会开始纠正它。使用库来做正确的事 - 你已经用 PHPMailer 标记了这个问题，但你没有使用它。您的代码基于 PHPMailer 提供的示例之一，而不是您在其他地方找到的示例，因为几乎所有示例都已过时或错误。

您还伪造了发件人地址，因此许多服务只会拒绝或退回您的邮件。从您自己的地址发送，并在回复中填写提交者的地址。

还要确保您的 SPF 记录配置正确，并且最好也使用 DKIM 对您的消息进行签名。
