In case you missed it for some reason, I replied to you on imap-use... http://mailman1.u.washington.edu/pipermail/imap-use/2007-September/000296.html What are your problems with what I said there? > Hence my question. > Is there any practical way to do replication using imap?

I don't believe that's a valid comparison. Subversion is a revision control system and so is very well suited to synchronising two repositories. I'm no IMAP expert, but I don't think IMAP has the facilities to easily locate where two mail stores differ and what operations might be required to make them the same. If something like svncync is really all you're after, then perhaps just use rsync on the mailstore files directly. If you choose the trigger for the rsync well it will probably do everything you want, and more safely than "replicating IMAP".
