                }

                MailAddress from = new MailAddress(ConfigurationManager.AppSettings["fromEmailAddress"]);

                message.From = from;

                SmtpClient smtpClient = new SmtpClient();

                smtpClient.Host = "10.222.1.123";

                smtpClient.Port = 25;

                smtpClient.Send(message);

                Misc.Log(DateTime.Now.ToString() + ": Mail sent Successfully");

            }

            catch (Exception e)

            {

                Misc.Log(e.Message);

            }




1.Create a method and place this code
2. Make the change like subject and smtp ip and port, mail template
3. else just replace the below code in your exiting code: 
MailMessage message = new MailMessage();
