Perform a DNS lookup to check a domain's current IP address & DNS records across a bunch of servers worldwide so you can determine the current state of DNS propagation.
So, I accidentally dragged some messages from Outlook onto Firefox a minute ago and was delivered to www.fromsubjectreceivedsizecategories.com, which, upon inspection reveals itself to be made up of the heading names of the columns I use to sort my e-mail. While I'm not going to reward them with a link, I've included a screen shot (click on the thumbnail for a large view) so you can see that it is the typical squatter's fare.
I'm curious as to how many variants they have running to account for all of the different combinations of columns and order. If I wasn't so amused by the pathetic nature of companies that do this crap, I'd cry for the brain cells, energy and time lost to such dumb pursuits. They should be doing something worthwhile. Like cutting my lawn with those snub-nosed scissors they give first graders or testing how long a human can exist in space without a pressurized suit.
