Check that a particular email address exists.

WARNING:
  Checking email addresses in this way is not recommended, and will lead to
  your site being listed in RBLs as a source of abusive traffic. Mail server
  admins do like it when they get connections that don't result in email being
  sent, because spammers often use this technique to verify email addresses.
