Okay, I found the error message, it's cryptic indeed. rename: No such file or directory (errno = 2) IIRC, I did understand it quite immediately when I saw it the first time. But maybe it was easy for me because I was quite familiar with the maildir format, having dealt with OfflineIMAP and I had been experimenting with Gmail's IMAP implementation to understand how it works. Having said all that, I do not think there is any easy solution to this issue. This is inherrent in how we are approaching the problem the moment we choose a solution that relies on syncing rather than being live (IMAP access). > And to close the circle, this example in fact has analogy with our > maildir situation: the MUA trying to set the "Replied" flag presumably > just sent off a reply. So the failure to set the flag means the maildir > state, while internally consistent, doesn't reflect reality. This is a very interesting case indeed. However I do not see any possible solutions as long as we choose to sync rather than use IMAP. In this particular case, the inconsistent flags will be corrected on the next sync, since the remote server has the correct flags. Cheers, -- Suvayu Open source is the future. It sets us free.
