Yes. Or, multiple connections could be maintained to monitor each (important/subscribed, perhaps) folder on the server. Impolite but, in service of a nearly-instantaneous update of the local maildirs, could be well worth it. The high cost of iterating over each folder, getting the statuses, doing the local comparison, then syncing changes is, I would imagine, the real reason you’d want a “daemon” mode. Well, I can dream …

Sorry about that—simply had to get my twopenneth in there. :)
