title: SMTP Service not available
body: <p>I am trying to create a web application which upon entering your email address and message , sends an email with this information from the email address.</p>
  
  <p>I used this:</p>
  
  <pre><code>    try
      {
          NetworkCredential login = new NetworkCredential("your_____@gmail.com", "password");
  
          System.Net.Mail.MailMessage email = new System.Net.Mail.MailMessage();
  
          email.To.Add(new MailAddress("my____email@gmail.com"));
          email.From = new MailAddress("your_____@gmail.com");
          email.Subject = "Question";
  
          email.Body = question;
  
          SmtpClient client = new SmtpClient("smtp.gmail.com");
          client.EnableSsl = true;
          client.UseDefaultCredentials = false;
          client.Credentials = login;
          client.Send(email);
      }
      catch
      {
      }
  </code></pre>
  
  <p>But its giving me an SMTP error.</p>
