 From the documentation:

mail.nntp.listall
If set to true, calling Folder.list on the root folder will
actually attempt to list all newsgroups. Since there are upwards of 
30,000
newsgroups on Usenet, this option should be used with caution. 
Otherwise a
small subset of default newsgroups are returned.

It looks like your news server doesn't return such a useful subset.

Note that the nntp provider doesn't create a .newsrc by itself: you 
need to create one yourself, and the nntp provider will update it with 
subscribed newsgroups and read articles.
