Fighting Spam With Your Mail application

I've start to use a function on my email client that sends a message to the sender of the email that states that my mailbox is not valid.
If the sender exists, he will think that my mailbox doesn't exist and it will remove the address form the list.
In the Mail.app on MacOSX the function is bounce.
