If you don't appreciate what this means, open your web browser, and enter an URL by running your hand across the keyboard, and add ".com" or ".net" at the end.
e.g. http://fbbgqqweffewq.com
Expecting a "server not found" message? Guess again:
We didn't find: "fbbgqqweffewq.com" There is no Web site at this address.

There are lots of DNS implications for this, not to mention wasted network bandwidth and caching proxy server. Perhaps people can start billing VeriSign for these wasted resources?
Next thing you know, they'll be selling banner ads up there for casinos and X10 equipment.

Actually I figured out how to use it to my advantage. I query "." which is my own DNS server of course as a ip4r blacklist and if the IP for verisign's site is returned then I give the spam a very high score. Any domain that doesn't exist would fail this, but any other domain would not return that IP, but rather the proper IP. I'm still pissed at Verisign, but I always try to turn a problem in to an opportunity so now I'm using their greed to block spam.
Just to clarify my own post. I meant a right hand side test so it is checking the address that the sender is claiming is theirs rather than how you typically check the host that is handing the mail to you. (It's late and I clicked send too quick.)
