Problem on sending email using yahoo

Hello

I am going to send the email using yahoo account.

Here is my code.

System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage("myaccount@yahoo.com", "toaddress, "Test", "Test");

   System.Net.Mail.SmtpClient emailClient = new System.Net.Mail.SmtpClient();

   emailClient.Host = "smtp.mail.yahoo.com";

   emailClient.Credentials = new System.Net.NetworkCredential("myaccount@yahoo.com", "mypassword");

   emailClient.Port = 465;

   emailClient.EnableSsl = true;

   emailClient.Send(message);

(I didn't write my real yahoo account & password.)

When I run this code, I get the error message 'An existing connection was forcibly closed by the remote host'.

Do you know why it is?

I have no problem when to set the port to 25 and set to the ssl to 'false'.

Please help me!

thanks in advice.

Thanks for your reply.

But I need to set the EnableSsl to 'true'.

Because sometimes the email sent with no ssl, is considered as a spam.

please check following link

http://www.emailarchitect.net/easendmail/dev/csharp.asp

you have to download EASendMail20.dll from there then do following

SmtpMail oMail = new SmtpMail("TryIt");
      SmtpClient oSmtp = new SmtpClient();
    
      //Your yahoo email address
      oMail.From = "myid@yahoo.com";
      //Set recipient email address
      oMail.To = "support@emailarchitect.net";
      //Set email subject
      oMail.Subject = "test email from yahoo account";
      //Set email body
      oMail.TextBody = "this is a test email sent from c# project with yahoo.";

      //Yahoo SMTP server address
      SmtpServer oServer = new SmtpServer("smtp.mail.yahoo.com");
      //yahoo user authentication should use your 
      //yahoo email address without domain part as the user name. 
      //For example: your email is "myid@yahoo.com", then the user should be "myid"
      oServer.User = "myid";
      oServer.Password = "yourpassword";

      //Because yahoo deploys SMTP server on 465 port with direct SSL connection.
      //So we should change the port to 465.
      oServer.Port = 465;
      
      //Send email over SSL/TLS connection.
      oServer.ConnectType = SmtpConnectType.ConnectSSLAuto;

      try
      {
        Console.WriteLine("start to send email over SSL ...");
        oSmtp.SendMail(oServer, oMail);
        Console.WriteLine("email was sent successfully!");
      }
      catch (Exception ep)
      {
        Console.WriteLine("failed to send email with the following error:");
        Console.WriteLine(ep.Message);
      }

Hope it will solve your problem.
