Getting newsgroup list in real-time

Hi,

I am trying to list all newsgroup available from a server. I found  
that the API
does not allow the listing of groups before the complete list is  
retrieved.

There is no getFolders() method on the NNTPRootFolder that would  
allow the listing of currently
known newgroups. For Mail the listing of folder is not that long, but  
for NewsGroups it takes a while.

I am missing something obvious ?

How could I get this information? Adding a ListListener parameter to  
the list() method, or a getFolders() method which could return the  
result of the current/last listing.

I understand that this would be outside of the JavaMail API, but it  
would be useful.

What do you think?
