今天使用腾迅企业邮发邮件时，发现 System.Net.Mail 不支持ssl，参考资料：https://blog.csdn.net/molu474305148/article/details/99713389

https 如果访问有问题，记得加上这段代码：

    // set remote certificate Validation auto pass
    ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(remoteCertificateValidate);
    ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;

private static bool remoteCertificateValidate(object sender, X509Certificate cert, X509Chain chain, SslPolicyErrors error)
{
    return true;
}
