To compile and run this program 'javax.mail.jar' will need to be present on your system and added to your classpath. Also if you're using the Google SMTP Server then, as well as requiring a gmail account, you'll probably need to temporarily turn on 'access for less secure apps' to prevent it from being blocked.
