Several internet applications require the ability to send email notifications. The J2SE platform includes the JavaMail API along with a JavaMail service provider that allows an application component to send internet mail. The JavaMail API has two parts:
An application-level interface used by the application components to send mail
A service provider interface used at the J2SE API level.
Java Mail Sessions are J2SE resources that can be created and managed by using Sun Java System Web Server.
Sun Java System Web Server does not provide an Administration Server interface to create Java Mail Sessions. You can use the command line interface to do so. For more information on how you can create a mail resource using the command line utility, see Create Mail Resource.
