PHPMailer - 通过 SMTP 和 Gmail 发送电子邮件

Question

我正在使用PHPMailer Form found here.

网站下载的示例是“Contact-3”，用于在 Bootstrap 主题中使用 PHPMailer 通过 gmail 发送 SMTP 电子邮件。当我使用“Contact-1”时，它可以完美地用于我的托管域电子邮件地址，但使用 SMTP 版本到 gmail 地址时，联系表单不会提交。

在下面的代码中，我更改了以下几行以添加我的 gmail 地址和 gmail 密码：

$sendToEmail = 'myemail@gmail.com';
$smtpUsername = 'myemail@gmail.com';
$smtpPassword = 'MyPassword';

非常感谢您对使用给定信息进行这项工作的任何帮助 - 提前致谢！

我怀疑您会因为使用gethostbyname 而遇到证书验证错误。该调用是针对配置错误的网络的一种解决方法，它不能与 SMTP+STARTTLS 结合使用，因为它总是会导致名称不匹配。尝试注释掉该行并使用 smtp.gmail.com 作为主机名。

使用 PHPMailer 提供的 gmail 示例作为参考，并更新到最新版本的 PHPMailer。
