Solution 2

I believe that you need to send email via GMail, please set the property of Port on the SmtpClient object (in your case it is smtp)to 465 or 587.

try the following code

SmtpClient serverobj = new SmtpClient();
string username = "your gmail is";
string pwd1 = "gmail password";
serverobj.Credentials = new NetworkCredential(username, pwd1);
serverobj.Port = 25;
serverobj.Host = "smtp.gmail.com";
serverobj.EnableSsl = true;
MailMessage msobj = new MailMessage();
msobj.From = new MailAddress(user, "Email", System.Text.Encoding.UTF8);
string str = "samplename@gmail.com";
msobj.To.Add(str);
msobj.Subject = "New Event Inforamtion";
msobj.Body = desc.Text;

serverobj.Send(msobj);
