Java EE (Java Enterprise Edition) General Discussion

Hi to all,
I'd like to know how to catch the unliverable messages.

I'm sending email through my class below, but I cannot catch if a message is not arrived, if the email is wrong and if the receiver has received my message.
I could I catch all these things?
Where do I find a complete list headers for JavaMail?

Thanks in advance, Himgi.
