C＃ - 从BlueHost发送电子邮件

Question

我有BlueHost，我无法使用C＃。我已经从我登录的页面中获取了详细信息：

然后我使用此代码尝试发送电子邮件：

MailMessage message = new MailMessage
{
    From = new MailAddress("toEmail@site.com", "toEmail@site.com")
};
message.IsBodyHtml = false;
message.To.Add("email@site.com");
message.Subject = "my subject";
message.Body = "body";
message.Priority = MailPriority.Normal;
SmtpClient client = new SmtpClient
{
    Port = 465,
    Host = "box263.bluehost.com",
    EnableSsl = true,
    Credentials = new NetworkCredential("myEmail@site.com", "myPassword"),
    Timeout = 10000,
    UseDefaultCredentials = false
};
client.Send(message);

即使它有足够的时间（10秒），也会抛出一个错误，表示它超时。即使我没有设置超时时间，它也只是坐了一会儿。我也尝试过没有SSL，禁用'EnableSsl'，将端口更改为'26'，并将主机更改为'mail.embirk.com'，但这也不起作用。此外，这适用于第三方软件，如Microsoft Outlook和东西。有任何想法吗？感谢。

修改 我还联系了Bluehost的二级支持技术人员，他们说他们也很难过。他们说他们用Thunderbird尝试过，这一切都奏效了。他们说可能正在寻找证书？

编辑2：

这个Outlook注册表是否有帮助。 （如果运行，这适用于Outlook。）

我会尝试在客户端块之外声明凭据并将其分配给客户端凭据。

实际上完全摆脱了阻止。

NetworkCredential myCred = new NetworkCredential("xxxxxxxx", "xxxxxxxx");


client.Credentials = myCred;
client.port = 465,
client.Host = "box263.bluehost.com",
client.EnableSsl = true,
client.Credentials = new NetworkCredential("myEmail@site.com", "myPassword"),
client.Timeout = 10000,
client.UseDefaultCredentials = false
