You still have a program that can be abused to send email to arbitrary addresses.
Have you not yet gotten spam that includes the line "below the result of your feedback form", and then goes on to try to sell you some Viagra or something?
That's the SPAM because someone set up a form just like yours and didn't secure it properly. I damn well want that IP address there, so I can track who sent it.
And you have the nerve to say:
I want to make it anonymous not to be abused or to abuse, but for the sake of doing it.
You smell like an abuser to me. I will not help you further, and I want no-one else here to help you either.
