Yeah, I should have mentioned that my own personal preference is to avoid
all this RE-based validation crap and just generate an email to the supplied
address that contains a URL that when navigated to confirms the validity of
the address.

That's much more straightforward, imho, and avoids all this, "What are the
valid tld's?" mess.  Just take whatever the user supplies and send them a
confirmation email.

But, to each his own,
