Hi,

Thunderbird uses the following IMAP command to list shared folders:

. list "" INBOX.shared.%.%

Dovecot 2.1.10 does not list any folders in response to this command.

Dovecot 2.0.21 does list them:

• LIST (\HasNoChildren) "." "INBOX.shared.user1.folder" . OK List completed.

Both versions list the folders if "*" is used instead of "INBOX.shared.%.%".

Because of this issue, shared folders are not shown in Thunderbird.

The ACL of the folder in question is ACL "keilrwtscd" for user1 (who is trying to access them using Thunderbird).

config:

# 2.1.10: /usr/local/dovecot/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-42-server x86_64 Ubuntu 10.04.4 LTS disable_plaintext_auth = no mail_gid = vmail mail_location = mdbox:~/mail mail_plugins = acl mail_uid = vmail namespace { inbox = no list = children location = mdbox:%%h/mail prefix = INBOX.shared.%%u. separator = . subscriptions = no type = shared } namespace default { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = scheme=CRYPT username_format=%u /usr/local/dovecot/etc/dovecot/users driver = passwd-file } plugin { acl = vfile acl_shared_dict = file:/mail/shared-mailboxes } protocols = imap pop3 service auth { unix_listener auth-userdb { group = vmail mode = 0660 } } ssl_cert =

Cheers, Christoph
