What do I need to acquire in order to get started with JavaMail?
John Zukowski The reference JavaMail implementation is available from Sun from http://java.sun.com/products/javamail/. You also need the JavaBeans Activation Framework extension from http://java.sun.com/beans/glasgow/jaf.html. If you intend to use JavaMail to read mail, you also need a POP3 provider and might wish to pick up the provider that Sun offers (also available from http://java.sun.com/products/javamail/).
The JavaMail libraries works with Java 1.1.x or greater.
