Issue with imap folder structure

[absolutely_free at libero.it]

Hi Steffen,


sorry, in this case "duplicate" means that users have two folders in webmail (Roundcube) with same content.

I did not tried to move messages between folders yte.

I confirm that on previous server, this was Dovecot's settings:

namespace {
type = private
separator = .
prefix = INBOX.
inbox = yes
}

After migration to new server (as I said I copied spool at filesystem level), I noticed that namespace settings was different:


namespace inbox {
inbox = yes
location =
mailbox Drafts {
special_use = \Drafts
}
mailbox Junk {
special_use = \Junk
}
mailbox Sent {
special_use = \Sent
}
mailbox "Sent Messages" {
special_use = \Sent
}
mailbox Trash {
special_use = \Trash
}
prefix =
}


So, I used "INBOX" prefix:


namespace {
type = private
separator = .
prefix = INBOX.
inbox = yes
}


and restarted Dovecot, but it seems I created lots of issues..

Now I restored  the original configuration.. it seems ok

Is it a bit unclear how configure properly Roundcube AND Dovecot (regarding IMAP settings)


Thank you very much
