void sendEmail(string strFrom
                        , string strTo
                        , string strSubject
                        , string strBody)
   {

       MailMessage objMailMessage = new MailMessage();
       System.Net.NetworkCredential objSMTPUserInfo =
           new System.Net.NetworkCredential();
       SmtpClient objSmtpClient = new SmtpClient();

       try
       {
           objMailMessage.From = new MailAddress(strFrom);
           objMailMessage.To.Add(new MailAddress(strTo));
           objMailMessage.Subject = strSubject;
           objMailMessage.Body = strBody;

           objSmtpClient = new SmtpClient("172.0.0.1"); /// Server IP
           objSMTPUserInfo = new System.Net.NetworkCredential
           ("User name", "Password","Domain");
           objSmtpClient.Credentials = objSMTPUserInfo;
           objSmtpClient.UseDefaultCredentials = false;
           objSmtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;

           objSmtpClient.Send(objMailMessage);
       }
       catch (Exception ex)
       { throw ex; }

       finally
       {
           objMailMessage = null;
           objSMTPUserInfo = null;
           objSmtpClient = null;
       }
   }
