National Do Not Mail List?

[Jim S.]

I just recently learned of the existence of this list but haven't been able to find out how to determine if a particular address is on it.  I'm guessing that these addresses could be weeded out with companies such as Listsource but this doesn't help much if you're building your own list by driving for dollars.  Does anyone have more information on this?  I've looked here on BP and have googled it but have come up empty.
