The only truly definite way I know of to verify an e-mail address is to send
a query, and if you get a valid response, it's a valid address. If you
don't, it's inconclusive.

In other words, make 'em validate their own addresses. If you're providing a
service which they've opted into, they'll expect it. If you're sp4mm1ng
them, they'll ignore you and be happy.
