VeriSign hijack domain typos

|The domain registrar VeriSign recently added wildcard DNS records to all .com and .net domains - redirecting surfers who get lost on the Net to a search page, called Site Finder, run by the company. Those who type in non-existent addresses will also be served up Site Finder, instead of an error message.|
This means that the basic 'sender domain does not resolve' check in sendmail and many other mail server software is now obsolete because any .net and .com now resolves. This will open the internet up to more spam.
The alterations will frustrate commonly used anti-spam techniques. Mail packages often check to see whether the domain an email is coming from is valid but with the changes all domains have suddenly become valid, frustrating the technique.
