[Dovecot] Maildir folders, separator = /, LAYOUT=fs (to support offlineimap)

[kkruzich]

I use offlineimap to pull down some Gmail mail stores. With offlineimap 
I use sep = / and nothing more exotic.

With dovecot I can see INBOX, messages, and messages in top level 
folders but not subfolders.


I'm dealing with folder structure that looks like this:

/opt/gmail/joe/Later
/opt/gmail/joe/Tech/Projects
/opt/gmail/joe/Tech/Projects/Fun
/opt/gmail/joe/Tech/Projects/Failed
/opt/gmail/joe/Tech/Projects/Planning


The folder Later has cur, tmp, new and I can see messages.

Projects is a container for subfolders Fun, Failed, Planning. I know 
Fun, Failed, Planning has messages but I'm not able to expand (via 
thunderbird) the folder Projects.

I have this configured in dovecot.conf

mail_location = maildir:/opt/gmail/joe:INBOX=/opt/gmail/joe/INBOX:LAYOUT=fs

namespace private {
    separator = /
    list = yes
}

And this is what's getting logged...
