PHPMailer-通过SMTP发送电子邮件

Question

我使用的PHPMailer表格在这里找到。

从网站下载的示例是“接触-3”，在引导主题中使用PHPMailer通过gmail发送SMTP电子邮件。当我使用“接触-1”时，它完全适用于我的托管域电子邮件地址，但SMTP版本适用于gmail地址，联系人表单不会提交。

在下面的代码中，我更改了以下行以添加我的gmail地址和gmail密码：

$sendToEmail = '[e-mail]';
$smtpUsername = '[e-mail]';
$smtpPassword = 'MyPassword';

任何关于使用给定信息进行此工作的帮助都将不胜感激-提前感谢！

$okMessage = 'Contact form successfully submitted. Thank you, I will get back 
to you soon!';

// If something goes wrong, we will display this message.
$errorMessage = 'There was an error while submitting the form. Please try again 
later';

我怀疑由于使用了gethostbyname，您将收到一个证书验证错误。该调用是配置不正确的网络的一种解决方法，它不会与SMTP STARTTLS结合使用，因为它总是会导致名称不匹配。试着注释掉这一行，并使用smtp.gmail.com作为主机名。

使用PHPMailer提供的gmail示例作为参考，并更新至PHPMailer的最新版本。
