No, you cannot do it. A good explanation as to why is here, http://stackoverflow.com/questions/3883518/can-i-check-if-an-email-address-exists-using-net[^]

Essentially, you can't ask an email server if the email is valid.

It is impossible, until you send a message and receive some response. This is not how mail system works. You can send a mail requesting delivery confirmation, it may or may not work. Some hosts will give you automatic response if the mail address on their host does not exist, but mail is rarely configured that way as it could simplify the work of the spammers. So, there is nothing you could rely on.
