SMTP 在主机上运行良好但在 bamboozle.me 主机上运行不正常？

请大家帮我解决以下错误？我使用的是 smtp php 邮件程序，它在托管程序上运行良好，没有错误，我确实收到了电子邮件，但它在我的 bamboozle 托管网站上不起作用。请帮助我。

这是我的代码

    // sendmail();  // call this function when you want to

    if (isset($_GET['sendmail'])) {
        sendmail();
    }

我还尝试更改端口值但没有发生任何事情，因为具有相同凭据和 smtp 设置的相同代码在托管商上运行。

Answer 1

请注意您如何在脚本中请求连接到 smtp.gmail.com，但它实际上是连接到 cp-dxb-001.bamboozle.me？

那是因为您的托管服务提供商将您的 SMTP 流量重定向到他们的邮件服务器，as described in the troubleshooting guide。

不幸的是，您禁用了 TLS 证书验证，因此它仍然可以连接，结果您泄露了您的 gmail 帐户的凭据，现在您需要更改密码。这里的教训是阅读错误信息，不要禁用证书验证。

您需要使用他们的邮件服务器，说服他们停止重定向您的 SMTP 流量，或者寻找更好的托管服务提供商。
