Check requirements for mail sending from Java

[UserXXX]

As we want to send information E-mails to administrators under certain conditions it is necessary to know what data is required to do so (outbox configuration).
One simple way is the JavaMail API and the Java Activation Framework (JAF).
Task: Create a little example program to know what data is exactly needed. The demo program should work (depending on configuration) with different mail providers (gmail, Googlemail, web.de, etc.).

"The JavaBeans Activation Framework 1.1.1 final release is included with the Java SE 6 release and is also available separately." ( source http://www.oracle.com/technetwork/articles/java/index-135046.html )
Thus only JavaMail is required as an external API.

Please note: If we use the JavaMail API we have to license under GNU GPL!
The reason for this is, that the JavaMail API is licensed under Common Development and Distribution License (CDDL) v1.1 and GNU General Public License (GPL) v2 with Classpath Exception (see http://glassfish.java.net/public/CDDL+GPL_1_1.html for the full license text).
