If you don't use MIME encoding, you don't need any additional jars for mail. However, if you use MIME encoding, you need the following jars:
mail.jar Mail task with Mime encoding, and the MimeMail task http://java.sun.com/products/javamail/ jsse.jar Support for SMTP over TLS/SSL in the Mail task Already included Java 1.4+ http://java.sun.com/products/jsse/ activation.jar Mail task with Mime encoding, and the MimeMail task http://java.sun.com/products/javabeans/glasgow/jaf.html If you are trying to mail out the results of your build, you should take a look at a good continuous build system that handles this task for you.
