System.Net.Mail.MailMessage myEmail = new System.Net.Mail.MailMessage ();
myEmail.Subject = "Test Innovator Email";
myEmail.Body = "Test Email.";
myEmail.From = new System.Net.Mail.MailAddress ("[email protected]");
myEmail.To.Add ("[email protected]");
CCO.Email.SetupSmtpMailServerAndSend (myEmail);
