This week's giveaway is in the EJB and other Java EE Technologies forum. We're giving away four copies of EJB 3 in Action and have Debu Panda, Reza Rahman, Ryan Cuprak, and Michael Remijan on-line! See this thread for details.
I suppose it's possible that you might have more than a theoretical question. In case you were interested in how to do that, go to the JavaMail section of the Ranch's JavaEnterpriseEditionFaq and follow some of the links there. Also there are example programs in the JavaMail download.
