Hello,

Not much to go on here, i remember running in to this same problem in some
early 1.0 rc's, but if i remember correctly it just was fixed in a later
release and started working. Any ideas how to proceed on this one? i could
setup a test enviroment and run strace if needed?

if i list the mail boxes it does not show the folders under shared:


* LIST (\Noselect \HasNoChildren) "/" "shared"
. OK List completed.

The subscribe and unsubscribe seems to be working:

C unsubscribe shared/shared-folder
C OK Unsubscribe completed.
C subscribe shared/shared-folder
C OK Subscribe completed.

I get this in the logs:

Jun 30 11:17:44 [dovecot] imap-login: Login: user=<username>,
method=PLAIN,
rip=127.0.0.1, lip=127.0.0.1, secured

safe_mkstemp(/var/mail/jaetut/temp.valas.17956.7b8393cabde89cbd) failed:
Operation not permitted

It seems to be the problem is with listing the folders? as if im
subscribed to the folders they work fine, but can not see the folders
again in imap? The /var/mail/jaetut folder has write permission to
everyone. any ideas?
