There is really no point validating emails beyond checking there is an @ in the address. Send an email to verify. You can even have an address with no . if you own the tld. foobar@me is a valid email.
Incorrect, I tried sending a mail and it bounced.
It is a valid email if the owner of the me tld sets up an email address on it. I'm not sure if anyone has done it on a tld but I have seen websites which are on the tld with no sub domain.
