It's by no means new and this has been discussed on this list before.
Try e.g. the following threads from the archives:

The archive is not perfectly threaded so you may want to look at the
monthly Subject index to make sure you have seen all relevant followups.

For the record, the main search page is at
    <http://www.rosat.mpe-garching.mpg.de/mailing-lists/procmail/>

getting recently has greatly increase, I would like to be more
agressive in getting rid of spam.. 

You're probably better off installing one of the wholesale solutions
like JunkFilter, Spam Dunk, or Spam Bouncer. There are many more. See
<http://www.iki.fi/era/procmail/links.html> for pointers. In the end,
the best solution is for your ISP to do SMTP and router level
filtering.

Hope this helps,
