[Dovecot] Sorting in IMAP list command?

[Ronald Johnson]

Hi All,

I'm running Dovecot 1.2.9 and have noticed the IMAP list command does 
not appear to send a sorted list of folders with list command.  For 
example on our Cyrus server I get a sorted list of folders (with INBOX 
listed first):

2 list "" "*"
* LIST (\Noinferiors) "/" "INBOX"
* LIST (\HasNoChildren) "/" "CalProject"
* LIST (\HasNoChildren) "/" "Deleted Messages"
* LIST (\HasNoChildren) "/" "Drafts"
...

while on our Dovecot server I get seemingly random listing:

2 list "" "*"
* LIST (\HasNoChildren) "/" "lsf"
* LIST (\HasNoChildren) "/" "mrg"
* LIST (\HasNoChildren) "/" "studiosysadmins"
* LIST (\HasNoChildren) "/" "Deleted Messages"
* LIST (\HasNoChildren) "/" "TriTeam"
* LIST (\HasNoChildren) "/" "systemupdates"
* LIST (\HasNoChildren) "/" "bb"
* LIST (\HasNoChildren) "/" "nagios"
* LIST (\HasNoChildren) "/" "server"
...

Is this intentional, or have I done something wrong?  I didn't see any 
option in the dovecot.conf to set the behavior of the list output.

Here is `dovecot -n`:
