C# - 从 BlueHost 发送电子邮件

Question

我有 BlueHost，但我无法让它与 C# 一起工作。我已经从我登录的页面上删除了详细信息:

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)，它也会抛出一个超时错误。即使我不设置超时时间，它也只是静置一会儿。我也尝试过不使用 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，这确实适用于 Microsoft Outlook 等第三方软件。有任何想法吗？谢谢。

编辑:我还联系了 Bluehost 的二级支持技术人员，他们说他们也被难住了。他们说他们用 Thunderbird 试过了，一切正常。他们说可能是要找证书？

这个 Outlook 注册表有帮助吗？ (如果运行，这适用于 Outlook)。

Answer 1

我会尝试在客户端 block 之外声明凭据并将其分配给客户端凭据。

实际上完全摆脱了障碍。

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
