Please don't scare the wotsits out of me, I've just abandoned Courier IMAP for two reasons:
- it seems incapable of handling subfolders anywhere but below the Inbox and the only help suggested is that I should ask the people writing my mail client to fix it - so that covers Microsoft (x2), Mozilla (x2), Eudora, Evolution and Squirrel mail for starters!
Of course it can't because it uses the brain-dead convention of folders all being files at the same level with '.' separators in the filenames indicating folders.
Thus a folder called 'holidays' is actually a directory called 'INBOX.holidays' and a folder called 'holidays/france' is a directory called 'INBOX.holidays.france'. Why any sort of mail server would want to construct a folder hierarchy like this I can never understand. It's not just Courier either, there are a few maildir based servers which do it.
(I'm not absolutely sure that the directories have the INBOX stuck on the front but however it's done they have to be all rooted in the same place because of the stupid idea of using '.' in the name rather than a really separate directory)
Sorry, I'm not following this one. The file structure behind my new Dovecot installation is exactly the same as that used behing my Courier one - and I've rebuilt from scratch on a new box, so the structure has been created cleanly by Dovecot. This may be related to the way the Debian package has been configured, I'm not sure.
The key difference is in the display on the client. With Courier it works on the basis that the Inbox (in my Maildir directory, which contains the cur, new and tmp subdirectories for it) has all the other folders below it (stored in physical directories within the same Maildir directory, using . seperators for the folder structure as seen by the client).
I thought (it is a while ago though) that Courier IMAP's maildirs had *directory* names like:-
fola.folb
fola.folb.folc
fola.fold.foleand that all these directories were rooted in the same place. There was no actual hierachy at all. The folders just had long names with dots in that the Courier IMAP server fed to the client such that they looked like real directories.
For a remote IMAP client this makes little difference except that of having them all rooted in the same place. For a local MUA it can be a significant issue.
I really have never understood why any maildir server (IMAP or otherwise) would want to do this. It's not how qmail does it.
