It depends on the prior art (what has been invented previously). One must compare your DMS to the ones which are presently known, to determine if there is a sufficient inventive difference (also known as being "nonobvious')between yours and the prior ones. Based on my own experience, I can tell you the spam filter/blockers are completely inadequate, so I hope you have invented something new. I can send you an Inventors Testimonial to assist you in documenting the date of your invention. Please let me know if you would like one.
