Our mailstore was converted from a Courier-IMAP system last year, but I am planning a migration to a shiny new VM, and would really like to clean things up and do away with the legacy INBOX namespace.
My goal is to simplify IMAP client setup - no special 'INBOX' namespace needed, they just enter the server info and credentials.
Also important because I will be rolling out SOGo, which has a nice web interface, and I want the mailstore to be as close to default dovecot settings as possible - although I do plan on converting from maildir to mdbox when I do the conversion
I also don't want other folders to show up as subfolders of the Inbox in IMAP clients, they should all show up on the same level as the Inbox.
I've read http://wiki2.dovecot.org/Migration/Courier, but I don't see anything about how to eliminate this stupid legacy INBOX. namespace, so that new IMAP clients won't show all folders as subfolders of the INBOX unless/until they add the INBOX namespace prefix in the advanced settings.
I've also been reading http://wiki2.dovecot.org/Namespaces, but I'm still confused as to how to go about this.
I don't think it can be done easily with just a single config. Whatever you do to new users might break existing setups. So the only good way I think would be to use two different IPs. One for the new setups, one for the old. For example imap.domain.com -> mail.domain.com or vice versa.
