Yes. A script to convert an exim3-style exim.conf files to the exim4-style equivalent already exists, written by Philip Hazel, the upstream author. In his own words: "It handles most cases, but of course it's not AI, it's just perl!". The problem is that exim's concepts have changed drastically in the areas of delivery to local mailboxes (that's now handled the same way as delivery to remote servers, which is a lot saner) and ACL's (an ACL concept has been added, rather than a whole bunch of configuration parameters, which also is a lot saner). The perl script tries to map variables to ACL rules and tries to map directors into routers in a correct way, but that isn't always possible. -- Wouter Verhelst Debian GNU/Linux -- http://www.debian.org Nederlandstalige Linux-documentatie -- http://nl.linux.org "Stop breathing down my neck."
