PHP表单电子邮件提交并非每次都有效

Question

编辑：这与可能的重复不同，因为他们从未收到电子邮件。我的随机发送。

下面的代码已经运行了将近一年。然而，在过去一周左右，它只在需要时发送。我的家伙在多个设备上的多个位置使用它，并且正在发生同样的事情。

有一个 html 表单可以提交到这个 php 代码，然后它会通过电子邮件发送给我并显示一个 html 确认页面。他们收到确认页面，但我没有收到电子邮件。当天晚些时候，如果我回击，然后再次提交，我确实会收到电子邮件。

我想不通。关于发生了什么的任何建议？我正在考虑创建一个它首先提交的 SQL 数据库，这样我就可以查看他们输入的内容，以防我没有收到电子邮件。

谢谢！

我建议使用专门为此目的设计的类，而不是使用原始邮件功能，查找https://github.com/PHPMailer/PHPMailer。
