In a real world scenario, email has become the most widely communication way in daily life. The main intention for proposing this paper is to enhance the security of email system, as there are various standards such as secure multipurpose mail extension(s/mime), pretty good privacy(pgp) etc. but they have a significant drawback that there headers are unauthentic. Because of unauthenticity of headers there are possibilities of impersonation attack, profiling of the email communication and can also lead to a spam and phishing activities. Here, we provide a technique to encrypt a data using graceful code and text based graphical password scheme using color combination for email system.

Keywords: Graceful code, Elgamal cryptography, RGB color model, XML (Extensible Markup Language).
