Hijacking
Yesterday, Verisign hijacked the Internet's Domain Name System. Any mistyped .com or .net address will now resolve to sitefinder.verisign.com. While this sounds like it might be innocent, it has one important ramification:
Spam - One of the best ways to guard a mail server against spam is to reject email from non-existent domains. This change will ensure that all domains exist and so rejecting non-existent domains will not work. There are workarounds for this. Blocking Verisign.com is my chosen route.
