saving nnfolders

[Dmitry Yaitskov <dimas@home.com>]

Hi,

I have (finally :) succeeded in setting up the expired articles to be
moved to nnfolders. What I don't like with the way it works now is,
after this expiration process I end up with all those updated nnfolder
groups as changed (and unsaved) buffers in my XEmacs. I'd like to

1. Have nnfolders save themselves each time a message is added (disk
   access if fast; losing articles - or having to restore them from
   auto saves - is bad).

2. Have these nnfolder buffers delete themselves at some point
   auto-magically (or perhaps just have them delete themselves after
   each article is added, after saving).

Any ideas or pointers to the relevant places in the docs would be
appreciated. Thanks.
