【中文标题】PHP 表单邮件不会返回带有@yahoo.com 地址的条目【英文标题】：PHP form mail will not return entries with @yahoo.com address 【发布时间】：2021-02-09 08:13:22 【问题描述】：表单邮件期望的结果：姓名、电子邮件地址和消息发送给网站所有者@yahoo.com。
表格问。 . . 姓名： 电子邮件： 留言：
当前状态： 如果将@yahoo 电子邮件地址放在表单的“电子邮件”字段中，（真实的电子邮件地址@yahoo.com）将不会收到电子邮件。如果“电子邮件”字段使用@gmail.com 或@godaddy.com 填写地址，则可以！下面是表单的 html 和 send.php 代码。
感谢您的帮助！

【问题讨论】：
您可以编辑您的问题并添加您的代码吗？我假设您的问题是为什么没有将电子邮件发送到雅虎电子邮件。 感谢您查看此内容！该问题已被编辑并添加了代码。 也包括您的validator.php 文件。可能是问题的原因
您的电子邮件很可能以垃圾邮件的形式到达，因为您发送的域与发件人标头中的域不匹配。不是代表用户发送，而是通过 Yahoo 的 SMTP 服务器中继电子邮件
好的，我试试，谢谢！
【参考方案1】：
如果您“从”任意地址发送邮件这几乎肯定会被阻止，因为这称为“欺骗”并且很容易被检测为非法。
您需要从您拥有和控制的地址发送。
Yahoo 对 SPF 记录非常严格，对 DKIM 非常严格，因此请确保正确设置和验证这两个记录。
每当您设置电子邮件表单工具时，请绝对确定不会有人劫持此工具以将任意内容发送到任意地址。如果这是可能的，那么某人将不可避免地发现这一点并用它来发送未经请求的邮件。
【讨论】：
感谢@tadman 看到这个。我在网站上填写表格时使用了合法的 yahoo 电子邮件地址，它们不会到达在 send.php 脚本中指定的 To: yahoo 地址。来自其他域的所有其他电子邮件测试都有效。 您无法通过自己的服务器发送电子邮件From: ...@yahoo.com。这是欺骗，将被阻止。您必须从您控制且可以正确配置的域发送。以上是关于PHP 表单邮件不会返回带有@yahoo.com 地址的条目的主要内容，如果未能解决你的问题，请参考以下文章
