    Dear Kaushik,

    It is really good. For a very long time I am using outlook express. Even immediately on installing “PostBox” I can find out the difference. Thanks for introducing this. Already “speak-a-message”, also introduced by you is very helpful and this is another useful utility. Thanks once again. And, what else this old man pray to the Almighty, except to Bless you a very happy and successful life?
