Question: Is it possible to validate an e-mailaddress by opening a socket-connection to the specified domein (@domain.com) and then search for username (user@domain.com) to validate an e-mailaddress? I know how to set up a socket-connection, but how do I search for the user in the given domain? Regards, bart
