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

Hi Martin,

As far as I do understand, umlaut domains only exist on the very client side
of a communication. This means that the mail client would have to translate
the domain name part of an email address to the IDN scheme.

I suggest that we add a little wrapper which does this job for mails sent by
TYPO3.

See this interesting thread (unfortunately in German only) about IDN in mail
addresses:
http://groups.google.com/groups?threadm=c1pgov.1ds.1@ich.michaelhermes.de

Don't forget that umlauts in the localpart of an address have ever been
valid!

I don't like the IDN scheme but I wouldn't like any other i18n method for
domain names as well! It's nothing but an easy way for drifting a few more
pence.

I'm looking forward to the day "they" announce case sensitive domain names.
It's so innovative, isn't it?!
