I think long ago I said I'd post the rules I use for filtering mailing
lists. Well here they are, as an exim filter, all generic - ie they
recognise new lists and create mailboxes for them.
The mail delivery is Maildir using an organisation of folders that works
well for Courier IMAP. It should be easy to modify for other storage
schemes.
These rules successfully handle all the mailing lists I have been on in
the last year *except* RISKS which I haven't looked at to fix as yet.
