While I was running dovecot 1.2.9, I had my mailboxes using the

old Courier IMAP format. i.e. my mailboxes would look like

INBOX.Orders.Scams

Going to dovecot 2 (but not 2.1), I see to have a few questions:

1. It seems I would device my mailbox thingies in 10-mail.conf:

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

mailbox SPAM { auto=subscribe special_use = \Junk }

mailbox Trash { auto=subscribe special_use = \Trash }

mailbox Sent { auto=subscribe special_use = \Sent }

}

but how would I prepresent my INBOX.Orders.Scams folder? Something like

mailbox Orders.Scams { auto=subscribe }

perhaps?

2. Reading (am I literate?) through http://wiki2.dovecot.org/Namespaces, it seems having separator = . is not only outdated but also a bad idea (but, I had child mailboxes as shown above). Could anybody elaborate one that? And which clients still do LSUB *?
