What do you specify as the SMTP host? It looks like it is not recognized or even empty.

i) Check if you have the required jar files ( mailer.jar, activation.jar, ...) in your class path.
ii) Disable any antivirus program running while trying to send mails. The antivirus may be scanning the ports and block it.
