public static Boolean SendingMail(string From, string To, string Subject, string Body)
{

try
{
MailMessage m = new MailMessage("Test<sender@gmail.com>", To);
m.Subject = Subject;
m.Body = Body;
m.IsBodyHtml = true;
m.From = new MailAddress(From);

m.To.Add(new MailAddress(To));
SmtpClient smtp = new SmtpClient();
smtp.Host = "mail.google.com";

NetworkCredential authinfo = new NetworkCredential("test@gmail.com", "te1234");
smtp.UseDefaultCredentials = false;
smtp.Credentials = authinfo;
smtp.Send(m);
return true;

}
catch (Exception ex)
{
return false;

Hi,
you have to check two things

1. toaddress that you have mentioned whether it's correct or not.
2. You should give the correct SMPT cleint instead of localhost
