It's close, but it won't ALWAYS tell you if in email is "deliverable".
Many configurations (some I've used in the past) *accept* mail for any
address,
and only later, if the delivery mechanism can't/won't deliver it locally,
will it
get bounced back as 'undeliverable'.
But in *some* cases, classes like this work.
