this wasn't valid with older function as well, i checked it.
i think for the context where you validate emails (in mail forms) these 
adresses shouldn't be used. You normally use this in intranets etc, do 
you really think this should be supported? Thing about i would enter 
this in a mail form:
john.doe at 127.0.0.1

it's useful for form validating imho and i have in mind that we split up 
  t3lib_div anyway, so later we could have one class for validating only.
