[Dovecot] ACL/shared-folder and Thunderbird

[Christian Roessner]

Hi,

I still have some problems with thunderbird and Dovecot. I added
ACL/shared-folders to dovecot. While everything is working perfectly
under Apple Mail and roundcube, thunderbird behaves very strange.

What I did:

1. Step
I have three mail accounts set up in thunderbird. In the second and
third account I managed IMAL-ACLs on the INBOXes, with following flags:

eilrwtsd

2. Step
At the first account, I chose IMAP subscriptions and I added both
INBOXes (shared/.../INBOX)

3. Step
Accounts were shown under shared. The folder shared and one level under
shared was wriiten in italic. The INBOXes were shown as regular.

4. Step
Clicking on each INBOX showed the mails. I chose properties and selected
to compress each folder, if it shows more than 100 mails.

5. Step
Closing Thunderbird and restarting it. Now thunderbird shows error
notifications that it could noct find a mailbox named shared/shared and
that mailboxes shared/system at service.intern and
shared/de1001 at service.intern would not exist. The folders shared and the
level beyond now is shown as regular folder. I still can see the mails
form the INBOXes. But each time I reopen Thunderbird, I get the same
error messages.

This is, what dovecot is logging:

Sorry to bother you once again with dovecot/thunderbird questions. It
all began by switching from maildir to mdbox (which I wanted to test for
shared file systems in the future...)

Thunderbird 3.1.11 (Ubuntu Natty version)

Best wishes and many thanks in advance
