/**
* <p>
* Factory class that creates a JNDI named JavaMail Session factory, which can be used for managing inbound and outbound
* electronic mail messages via JavaMail APIs. All messaging environment properties described in the JavaMail
* Specification may be passed to the Session factory; however the following properties are the most commonly used:
* </p>
* <ul>
* <li><strong>mail.smtp.host</strong> - Hostname for outbound transport connections. Defaults to <code>localhost</code>
* if not specified.</li>
* </ul>
* <p>
* This factory can be configured in a <code><Context></code> element in your <code>conf/server.xml</code>
* configuration file. An example of factory configuration is:
* </p>
*
* <pre>
* <Resource name="mail/smtp"
* auth="CONTAINER"
* type="jakarta.mail.Session"
* mail.smtp.host="mail.mycompany.com"
* />
