    This is nothing new and was one of the topic in blackhat.

    No.  This is NOT the only solution.  The proper solution is ECL - 
    Execution Control List.  ECL is a security control mechanism that is 
    available in both R4.6x and R5.x.  Lotus already published an article on 
    their website in April 2001 to remind users of the security 
    implications.  Go to
    http://www.lotus.com/home.nsf/welcome/securityzone
    and select
    "Lotus Notes Stored Form Vulnerability"
    (Stored Form is another way of putting executable codes in a Lotus e-mail).
