I found some errors in sending mail from a GoDaddy server, and after searching a lot I found the correct solution to send mail.
First add these namespaces in your project
using System.Net.Security;
using System.Security.Cryptography.X509Certificates;
using System.Net;
using System.Net.Mail;
Now the send mail method is
public void Send_User_Confirmation_Mail()
{
MailMessage mail = new MailMessage();
mail.To.Add("<email to send>");
mail.From = new MailAddress("<send mail>");
mail.Subject = "Account Created.";
string Body = "<body>";
mail.Body = Body;
mail.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient();
smtp.Host = "relay-hosting.secureserver.net";
smtp.EnableSsl = true;
smtp.Credentials =
new System.Net.NetworkCredential("<send email>"), "<send password>");
ServicePointManager.ServerCertificateValidationCallback =
delegate(object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
{ return true; };
smtp.Port = 25;
smtp.Send(mail);
}
These are main things to add with your normal mail sending code.
smtp.Host = "relay-hosting.secureserver.net";
smtp.EnableSsl = true;
smtp.Credentials = new System.Net.NetworkCredential(ConfigurationManager.AppSettings["Send_Mail_From_Email"].ToString(), ConfigurationManager.AppSettings["Send_Mail_From_Password"].ToString());
ServicePointManager.ServerCertificateValidationCallback = delegate(object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { return true; };
smtp.Port = 25;
Before adding there 3rd line of credential I was getting error of some invalid certificate issue to send a mail. But adding these all the issue become normal and mail is sending without any problem.
