[Dovecot] Thunderbird trouble with Dovecote and dbox

[Hannes Dorbath]

Hi,

I'm new to Dovecot -- migrating from Cyrus.

Version and config:

# 1.1.beta14: /etc/dovecot/dovecot.conf
protocols: imaps
login_dir: /var/run/dovecot/login
login_executable: /usr/libexec/dovecot/imap-login
mail_location: dbox:/data/mail/%u
auth default:
   passdb:
     driver: pam
     args: *
   userdb:
     driver: passwd

Linux 2.6.22-gentoo-r10 x86_64 GNU/Linux

I have chosen dbox as mailbox format as it is claimed to be the best 
performing -- and performance is the reason I'd like to migrate away 
form Cyrus. I'm aware that dbox might not be 100% mature, but I'm good 
at doing backups. Anyway, so far I have the following problems:

- Greyed out Inbox
   After creating a new user and connecting to that account with
   Thunderbird the first time, the INBOX folder is greyed out and in
   italic. Restarting Thunderbird 3-4 times seems to fix the problem.
   Google suggests that other people have seen the same, but they never
   found a solution.

- After creating sub folders they are not displayed, I need to manually
   subscribe to them after creation.

- When "Trash" contains folders, Thunderbird is unable to "Empty Trash".
   While the folder is removed from Thunderbird's folder tree, it's there
   again after a restart of Thunderbird.

- Deleted folders are never deleted from the file system. I'm not sure
   if this is intended with dbox.

- Moving folders via drag & drop does not work, it just does nothing.

So basically nothing besides reading existing mails seems to work reliable.

My basic questions now is, are those problems related to dbox, or to 
Dovecot and Thunderbird in general?
