Comment:

 This patch will allow dotless e-mail domains as long as the server can
 resolve the domain via a DNS lookup.  It should allow "localhost" and
 other development domains, but prevent "fakedomain" (unless fakedomain
 resolves on your network).

 If DNS times out on an invalid dotless domain, there may be a delay of up
 to 2 seconds.  This should be encountered rarely, but, due to the stacking
 of sanitize_email() and is_email() may be encountered twice in a row.

 Thoughts about this approach?
