        <network host="smtp.gmail.com" password="******" userName="noreply@yourdomain.com" port="587" />

      </smtp>

    </mailSettings>

  </system.net>

C# Send Mail Code:

            try

            {

                MailMessage message = new MailMessage();

                message.From = new MailAddress(tbxEmail.Text);

                message.To.Add(new MailAddress(_supportEmail));

                ExceptionHandler handler = new ExceptionHandler();

                handler.LogException(ex,

                    SeverityLevel.Critical,

                    "Contact Form Message could not be sent to support email",

                    GetType(),

                    "SendMessageEmail");

            }

//---------------email code

</configuration>

End when you send email just enable SSL on your SmtpClient:

var message = new MailMessage("navin@php.net");

// here is an important part:

message.From = new MailAddress("example@domain.com", "Mailer");

// it's superfluous part here since from address is defined in .config file

// in my example. But since you don't use .config file, you will need it.



var client = new SmtpClient();

client.EnableSsl = true;

client.Send(message);
