altnamespace with cyrus 2.3.3 and thundebird

[Chris Wesdorp]

Hello,

After using Cyrus 2.1 for a few years I wanted to use a new Cyrus
version on my new server. Although it is not yet marked as stable I
downloaded version 2.3.3 and tried to connect to it with Thunderbird
1.5.0.2. The host system is a LFS 6.1 system.


Although I set the altnamespace option in the imapd.conf file all
folders are shown beneath the INBOX. When I checked the namespace
options in Thunderbird it came up with these values:
Personal namespace: "INBOX."
Public namespace:   ""
Other users:        "user."

Comparing these values to my old Cyrus version (2.1.15)
Personal namespace: ""
Public namespace:   "Public Folders."
Other users:        "Other Users."

Creating folders in Thunderbird with the mailbox select (1 level higher
than inbox) works but in cyradm these are created at root level, no
prefix what so ever. I tried to set the sharedprefix and userprefix
option but it did not help. Thunderbird configuration allows these
settings to be taken over from server. But also disables and filling the
2.1.15 values does not solve the problem.

Is this a bug of I am missing somehting here?

Regards,
Chris Wesdorp
