Free
Spam Filters can be downloaded from the internet. Install one on your machine so as to safeguard both your personal electronic mailing account and your free dispensable one. It would do you no good whatsoever to install more than one of these actual programs. Or, better yet, you could get a free dispensable mailing account with a free functional spam filter! Plus, go install a free third-party spam filter so as to further strengthen your anti-spam solution.
