title: Validation fails for [DataType(DataType.Email)] in MVC3
body: <p>It seems that the internal validation in the DataType DataAnnotation for DataType.Email fails when the email address starts with a number.  I ran into this when a user with a 1234Something@gmail.com style email address tried to register on my site and their address was reported as "invalid".  After some experimentation, it seems that the leading digit is the culprit.  </p>
  
  <p>I haven't been able to find anything about this online.  Anyone know if it's a known issue, or did I by chance discover a new bug? :)  Is this something about the standard email address format that Microsoft got right and Google is doing incorrectly?  Is there a work-around?</p>
