It is quite legal for an SMTP server to accept messages for an address which does not exist, as long as it sends a DSN (Delivery Status Notification, AKA "bounce message") back eventually. Additionally, if something goes wrong, even the DSN can be lost. Thus, there is no way to know for sure if an address works without sending mail to it and asking if the other end receives it. -- Ben Scott <[EMAIL PROTECTED]> | The opinions expressed in this message are those of the author and do not | | necessarily represent the views or policy of any other person, entity or | | organization.
