Since i totally switched my mail system to imap, i’m looking for a way to keep the folders ‘small as possible’. I talked w/ Phil about this, and he (http://base-art.net/wk/Article/3.html) hacked a existing python script. The main difference between his hack and the orginal one, is that now the folder are archived in a ‘normal’ way.
This should only work w/ courier-imap server but this is the one i use :) . I can now read mailing archive without too much pain !
