And with catchall accounts and unexpected mail server behavior you may get no response even if an email address is not valid. IMO, the only way to verify that an email address exists *and* is being used by the person who supplied it (I assume in most cases this is the whole point) is to send a unique string or URL and check that the recipient responds with the string in an email or visits the URL. -- Steve Werby President, Befriend Internet Services LLC http://www.befriend.com/
