There are two different things here. You're talking about using the  
JavaMail API to get the article. There isn't an API function to do  
this (by message-id) in JavaMail (I expect you could use the search()  
method but this isn't implemented specially for NNTP anyway so it  
would be very inefficient).

But you can use the lower-level inetlib API to do it. If you're  
building a serious newsreader you'll want more control in any case  
(like how to handle newsrcs) and the MIME framework JavaMail provides  
is unlikely to be relevant. So just ignore JavaMail and manage a pool  
of NNTPConnections directly.
