Hey there!

1. Create an account that will have a quota large enough to get copies of ALL mail. (e.g. archiveall@yourdomain.com)
2. Set "always_bcc" to that address.
3. In the admin view, "view mail" as archiveall@yourdomain.com (or alternatively; login directly as that account)
4. Go to "Options"
5. Go to "Mail Filters"
6. Set rules accordingly.

Hope that helps.. Let me know if you are still having trouble.
