92% Junk

Out of 19,763 emails sent to me in the past several months 18,272 were spam (92%). Do I get a lot of spam or not many legitimate emails?
Well, I get hardly any spam as I have Mailwasher. It lets me delete junk mail at the server before downloading. Its great software and in addition to the time saving there is great satisfaction blitzing all that junk mail before it even gets to you.
However, I do wonder how much better the internet would be without all that junk flowing around.
