Re: [Dovecot] IMAP - many folders?

So my question is "how hard would it be to change sources to make '/' to be default delimiter"?

Very.

Maildir specifically uses .folder.folder names so that the IMAP server can find _all_ the folders by reading a single top-level directory. If sub-folders were stored ../folder/folder, then the IMAP server would have to scan the entire mail directory (in my case, several gigabytes) every time it started up, so it could find the list of folders.
