One can of course think in many ways here. Currently there seem to be 10 
proposed new TLDs: http://www.icann.org/tlds/stld-apps-19mar04/

And as Mattias pointed out it seems to be very difficult to write an 
entirely correct regexp for a valid mail address format. What about the 
current regexp in Emacs? Does it give many false positive? Or, maybe 
worse, many false negatives?
