System.Net.Mail.SmtpException：操作已超時。在asp.net中的錯誤使用godaddy託管發送郵件代碼

Question

我正在使用以下和平的代碼發送郵件使用godaddy託管。

但其拋System.Net.Mail.SmtpException: The operation has timed out.

protected void sendmail() 
    { 
     var fromAddress = "frommailid@site.com"; 
     // any address where the email will be sending 
     var toAddress = "to@gmail.com"; 
     //Password of your gmail address 
     const string fromPassword = "mypassword"; 
     // Passing the values and make a email formate to display 
     string subject = "HI test mail "; 
     string body = "From: pro@e-hotelspro.com"; 
     // smtp settings 
     var smtp = new System.Net.Mail.SmtpClient(); 
     { 
      //smtp.Host = "relay-hosting.secureserver.net"; 
      smtp.Host = "smtpout.secureserver.net"; 
      smtp.Port = 80; 
      smtp.EnableSsl = true; 
      smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network; 
      smtp.Credentials = new NetworkCredential(fromAddress, fromPassword); 
      smtp.Timeout = 20000; 
     } 
     // Passing values to smtp object 
     smtp.Send(fromAddress, toAddress, subject, body); 
    } 

Answer 1

我覺得這是System.Net.Mail著名SSL問題

System.Net.Mail with SSL to authenticate against port 465

你應該使用一些外部庫或等到微軟在框架版本中包含此功能

Answer 2

只是改變：

smtp.Timeout = 20000;

要

smtp.Timeout = 2000000;
