[Dovecot] \NoSelect on missing folders in LIST

[Peter Mogensen]

Hi,

I noticed a difference between courier and dovecot, and I'm not sure 
which of them is wrong wrt. RFC3501 - if any.

I have a Maildir which has been accessed by an Apple Mail client, so it 
got folders like:

INBOX
INBOX.Trash
INBOX.INBOX.folder
INBOX.INBOX.folder.a
INBOX.INBOX.folder.b

The INBOX.INBOX folder does not exist on disk and is not subscribed.

Courier responds to:
. list "" "*"
with
* LIST (\Noselect \HasChildren) "." "INBOX.INBOX"

But dovecot does not list that folder using "*".

However, if you issue:
. list "" "INBOX.%"

Dovecot answers:
* LIST (\Noselect \HasChildren) "." "INBOX.INBOX"

This makes some clients using "*" to get the folder list ignore the 
folderes below "INBOX.INBOX".
I know the recommended client way is to use "%", but I'm still curious 
about which is the correct behaviour.
