                NetworkCredential oCredential = new NetworkCredential("SMTP UserName", "Password");
                oSmtp.UseDefaultCredentials = false;
                oSmtp.Credentials = oCredential;
                oSmtp.Send(oMsg);
                Console.WriteLine("Mail sent");
                Console.ReadKey();
            }

            catch (Exception ex)
