Mining the bounce may produce upto 30+% more

Since the spammer are not throwing anything new, I decided to try a test. I took several hundred bounced emails and looked for a URL (http://etc). After the usual clean up, I got about 75 domain names. Of that, 50 names were already in my database. This means that possibly 30+% are have not made it to my filters. I say 30+% because a few of the domain names look legit.

I should note that I have additional sets of old spam, some going back 4 years.
