The only way you can know if an address is valid is if the recipient confirms that it is valid. Otherwise, you have to check that the domain exists, accepts mail, and does not reject or bounce the message. There is no general purpose way to do so without attempting to send the message. Even then the server may not bounce the message to thwart dictionary spamming attacks.
