        MailMessage mailObj = new MailMessage(from_m ,txbemail.Text,sub,mbody);
        SmtpClient SMTPserver = new SmtpClient("localhost");
        try

            SMTPserver.Send(mailObj);
        }
        catch(Exception ex)
        {
            Label7.Text = ex.ToString();
        }
        txbemail.Text = "";
        txbpwd.Text = "";
        if (flag == 1)
        {
            //Session["Ufname"] = txbemail.Text;
            btsignin.PostBackUrl = "staff_profile.aspx";
        }
        else
        {
            Label6.Text = "Invalid User,<br />Check Your Email Id and Password.";
            //Response.Write("Not an authorised user.");
        }

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;

thanks for your help..and for considering me...

sorry again the same error occurs.
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
