If I type name@outlok.com instead of name@outlook.com, it says the email is valid - when in fact it is not.


The domain outlok.com has an A record which points to 208.87.35.108 which I can even connect to on port 25 (though I don't perform that test). Until you actually mail that address there's no way to distinguish this from a valid email.


Who says it's not valid?
