printing to terminal

Sir,
           in the .forward file I have given my own file name instead of 
procmail
so that whenever mail arrives my program is executed.In my program I save the 
mail it works.The only thing that doesn't work is printing to a terminal.
I wan't to indicate the user that mail has arrived.I used printf and also
tried writing to my term the program did not print but nevertheless it saved
the mail.I guess that the problem is that the standard output is duped to
some other pipe discriptor whose other end is the mail daemon itself.
Please tell me what the problem is and also the solution.I also wan't to know
how procmail writes to terminal.

                                                     Yours sincerely,
                                             I.S.S.PRAMOD.
