dovecot - Dec 2009 - irregular problem on outlook + imap

Hi list,
my customer say me that "sometime" he has a problem with imap server 
when he try to move a mail from a folder to another. The error are:
""" NO [TRYCREATE] Mailbox doesn't exist: folder.with.dots
and spaces
and numbers"""

Like now I had connected to the server for create a "tcpdump |
strings"
session and the results are:

vj8q OK Idle completed.
can9 LIST "" "INBOX"
dtZ@
* LIST (\HasChildren) "." "INBOX"
can9 OK List completed.
zp2p LSUB "" "*"
* LSUB () "." "a_folder"
<-cut folder list->
* LSUB () "." " folder.with.dots and spaces and numbers"
<-cut about 600 folders->

and at the end:

zp2p OK Lsub completed.
3j1@
znem IDLE
2tw@
+ idling
(jI@
DONE
Atx@
znem OK Idle completed.
lylu APPEND "folder.with.dots and spaces and numbers" (\Seen) 
"30-Nov-2009 10:34:00 +0100" {280844}
lylu NO [TRYCREATE] Mailbox doesn't exist: folder.with.dots and spaces 
and numbers
xbci IDLE

On the maildir home (maildir:~/mail/), it's present the folder.with.dots 
and spaces and numbers and the same into the "subscriptions" file

My env:
debian lenny with last dovecot (1.0.15-2.3)
On the log, there is nothing special.

What can be?

Thanks,
Michele

This means it's in the subscriptions file.

This means it doesn't really exist, even though it's subscribed.

Are you sure it's really in the ~/mail/ directory exactly the same? You
could try also talking IMAP directly:

telnet localhost 143
a login user pass
b list "" "folder.with.dots*"

Is it listed?

Anyway it should work fine:

a create "folder.with.dots and spaces and num1234"
a OK Create completed.
b append "folder.with.dots and spaces and num1234" {10}
+ OK
From: foo

b OK Append completed.

	Hi Folks,

	This may relate to one of the few problems I see with dovecot.
	This had nothing to do with outlook; rather mutt or kmail.

	A couple years ago, sendmail delivered my mail to
	~/Mail/<user> and I could cd to ~/Mail and grep and find the
	string(s) sought.  

	Dovecot seems to save its mail on my mailserver as
	~/Mailbox/<dotuser>/*.  What do I change in the conf file to
	get rid of the directory DOT prefixes?  

	If there is any documentation on this, please point me at it?

	tia.

Do you know when/why this can happen?

No! But since it's passed some days, my customer modify / rename and 
delete some folders and I don't know if because he touch that folders or 
because there is a problem. Tomorrow I'll call him and I'll let you
know.

Thanks a lot,
Michele
