Rebuilding the index or re-adding the imap account works for a short while before it becomes corrupted again a week or two later. The mailbox has 1500 directories, 162054 files and around 40GB in size - but users don't tend to subscribe to all folders and only downloads the headers. Is there an optimum number of files/directories/size for a shared mailbox in cyrus?
