[Typo3-dev] Improvement of function validEmail($email)

[Dominic Brander]

hi
if you are working on an improved email validation please do remember 
that in the nearest future mails like müller at müllermilch.de will be 
possible... and don't forget about all the other possibilities...

have fun with that ;-)

cheers
