Mate,

It looks that you haven't added the code for SMTP server.
May I ask what SMTP server are you using??
Also you need to configure the port number..

It's a repost.

There may be two cause:
1. This usually results from trying to connect to a service that is inactive on the foreign host. 2. Sometimes a 10061 error is caused by either a firewall or anti-virus software presence on the local computer or network connection.

Either one may be blocking the ports needed to make a successful connection to the server. Either you went to the wrong host, or the server application you're trying to contact is not executing. Check the destination address you are using. Check, if you used a hostname, did it resolve to the correct address or not..

According to me port is the problem,
So Please Check below method.

C#

var fromAddress = "Gmail@gmail.com";
  // any address where the email will be sending
  var toAddress = YourEmail.Text.ToString();
  //Password of your gmail address
  const string fromPassword = "Password";
   // Passing the values and make a email formate to display
  string subject = YourSubject.Text.ToString();
  string body = "From: " + YourName.Text + "\n";
  body += "Email: " + YourEmail.Text + "\n";
  body += "Subject: " + YourSubject.Text + "\n";
  body += "Question: \n" + Comments.Text + "\n";
  // smtp settings
  var smtp = new System.Net.Mail.SmtpClient();
  {
      smtp.Host = "smtp.gmail.com";
      smtp.Port = 587;
      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);

Solution 4

If your system is in proxy server then your mail will not send. Please check your server first.
