Question

When I remove the comment “//stmp.timeout” it gives timeout error. What should I do to fix that?

Here is my code:

public ActionResult Index(EmailModel model)
{
    var smtp = new System.Net.Mail.SmtpClient();
    {
        smtp.Host = "smtp.gmail.com";
        smtp.Port = 180;
        smtp.EnableSsl = true;
        smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
        smtp.Credentials = new NetworkCredential("[e-mail] ","somepassword");
        //smtp.Timeout = 20000;
    }
    try
    {
        smtp.Send("[e-mail]",model.To, model.Subject, model.Message);
        return View("Index");
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex);   //Should print stacktrace + details of inner exception
         if (ex.InnerException != null)
         {
             Console.WriteLine("InnerException is: {0}", ex.InnerException);
         }
    }
    return View("Index");

In this line

smtp.Credentials = new NetworkCredential("[e-mail] ","somepassword

there is a space after gmail.com. This could prevent the login to gmail. Remove it.
Also, I think that the port used to send mail to gmail is 465 for SSL or 587 for TLS/STARTTLS.

smtp.Port = 465;
