This program is meant to aid users migrating from procmail to Mail::Audit. It reads in procmail .rc files, and spits out a first approximation to a Mail::Audit filter which will perform the same filtering. You'll need to edit it, of course, and there's still a lot it can't do. But it'll give you a good start.
