Asp.net mvc 4 send email

Question

I am working on ASP.NET mvc 4. I am trying to send an email using smtp client.I am using localhost right now.However, my code throws an error of "UNABLE TO CONNECT TO A REMOTE SERVER". Could anyone help me what I am doing wrong?

My code:

using System.Net.Mail;
using System.Net.Mime





  MailMessage msg = new MailMessage();
            SmtpClient client = new SmtpClient();


            try
            {
                msg.From = new MailAddress("[email protected]", "Display name");
                msg.To.Add("[email protected]");
                msg.Subject = "Password";
                msg.Body = "This is the test";
                msg.Priority = MailPriority.High;
                msg.IsBodyHtml = true;

                //the actual email and to send the picture in the image.........

              //  return "reached here";
                string str = "<html><body><h1>picture</h1></br></body></html>";
                AlternateView av = AlternateView.CreateAlternateViewFromString(str, null, MediaTypeNames.Text.Html);
              //  LinkedResource lr = new LinkedResource("C:/RANJAN'S/PROJECTS/Darn/Darn_3/darnCoupon/darnCoupon/Images/Carousel/carousel_1.jpg", MediaTypeNames.Image.Jpeg);
              //  lr.ContentId = "image1";
              //  av.LinkedResources.Add(lr);
                msg.AlternateViews.Add(av);



                client.Host = "smtp.gmail.com";
                client.Port = 587;

                client.DeliveryMethod = SmtpDeliveryMethod.Network;
                client.Credentials = new System.Net.NetworkCredential("[email protected]", "Password");
                client.UseDefaultCredentials = false;
                client.EnableSsl = true;

                client.Send(msg);

                return "reached here toooooooo";

              //  return msg.ToString();

            }
            catch (Exception ex)
            {

                return ex.InnerException.Message;

            }

            return "nothing happpened";


        }

You still need to change your password. stackoverflow.com/posts/17602292/revisions — SLaks

I suggest you download and install Smtp4Dev from here (http://smtp4dev.codeplex.com/). Once you install this you will be able to tell if the mail was sent regardless of you smtp server settings. Once you establish that the source of the problem is not your code then you can see what's going on with your smtp server settings.

Try this code. I hope it will work as you expect.

SmtpClient client = new SmtpClient();
            MailMessage msg = new MailMessage();                
            MailAddress to = new MailAddress("client email address");
            MailAddress from = new MailAddress("Your Email Address");
            msg.IsBodyHtml = true;
            msg.Subject = "Mail Title";
            msg.To.Add(to);
            msg.Body = "Your message";
            msg.From = from;
            client.Send(msg);

In web.config file under configuration section, you need to write the credential information of your mail account

    <system.net>
    <mailSettings>
      <smtp deliveryMethod="Network">
        <network host="smtp.gmail.com" port="587" userName="your email address" password="your password" defaultCredentials="false" enableSsl="true" />
      </smtp>
    </mailSettings>
  </system.net>
