Why? Should someone arrive at your Sales or Emergency window
in your office, naked, what would you do?
"Off the table" is IMO the correct action for an email address
that is naked -- i.e., that has no verification information.
Note that this is nothing new. We already do this with IP numbers.
If you send me a packet with a non-verifiable source IP there
will be no communication possible. Why should it be different
with email addresses?
