IIRC I did this once and Indeed you can. AFAIK, once Cyrus IMAP commits a message to disk, its backing file is not changed, just unlinked (maybe due to an atomic rename). Someone please correct me if I'm wrong... rsync -H will also work, but it can be painful. YMMV. I'd test the hardlink tool on a copy of the spool first, especially if you already have a lot of hardlinked files in it, and some are two sets of hardlinked files with the same content (it would actually be joining several clusters of hardlinks into single a larger cluster...). -- "One disk to rule them all, One disk to find them.
