Sending mail using asp.net

Question

Hi ,

 

      I have to send mail using private server. But i receive " Failure sending mail. " error 

 

My code 

 

private static void SendMail()

{

try

{

string SmtpHost = ConfigurationManager.AppSettings["SmtpHost"].ToString();

string SmtpFromMail = ConfigurationManager.AppSettings["SmtpFromMail"].ToString();

string SmtpFromMailPwd = ConfigurationManager.AppSettings["SmtpFromMailPwd"].ToString();

//foreach (DataRow dr in objDataTable.Rows)

//{

MailMessage mail = new MailMessage();

mail.To.Add("[email protected]");

mail.From = new MailAddress(SmtpFromMail);

//string EventName = DicEventTypeName[dr["Email"].ToString()];

mail.Subject = "Testing";

mail.Body = "Test";

SmtpClient smtp = new SmtpClient();

smtp.Host = SmtpHost; //Or Your SMTP Server Address

smtp.Port = 25;

smtp.Credentials = new System.Net.NetworkCredential(SmtpFromMail, SmtpFromMailPwd); // 

smtp.EnableSsl = true;

smtp.Send(mail);

}catch(Exception e)

{

}

}

 

Could you give any suggestion ?

 

Thanks in advance !!
