I have Fedora Core 2 and dovecot-0.99.10.4-4. I've done nothing to configure it but it seems to have
found the Mail dir in my home directory ok and I can connect using IMAP. But I can't create subfolders.
If I right click on inbox, there's a 'New Folder...', but if I create one then right click on it, no more 'New Folder...'. So it seems folders can only go one level deep.
