Spammers Breaking DNS

eWeek came out with an article about a new trick that spammers are using to make it more difficult to find and prosecute them. What spammers are doing is sending out millions of SPAM early in the morning point to non-existing domain name. Then they register the domain name, hoping to escape the CAN-SPAM fines via
this technical loophole.

The problem arises when millions of SMTP servers are attempting to perform DNS lookups for domains that don't exist, which causes all kinds of timeout problems.
