[Dovecot] IMAP ACLs not working

18 Mar 2009


      Hi,
I've some problems to get folder ACLs working with Dovecot. I've
defined some folders (like drafts, spam etc.) for every user and
created a dovecot-acl file in every folder so that users can not
delete or rename these folders but this does not work as expected.
Config
Debian Lenny 5.0
Dovecot 1.0.15
dovecot.conf
protocols = imap
protocol imap {
listen = xxx.xxx.xxx.xxx
}
disable_plaintext_auth = yes
log_timestamp = "%Y-%m-%d %H:%M:%S "
ssl_disable = yes
mail_location = maildir:/home/vmail/%Ld/%Ln
namespace private {
separator = .
prefix =
inbox = yes
}
mail_privileged_group = vmail
protocol imap {
mail_plugins = acl
}
protocol lda {
postmaster_address = postmaster@example.com
hostname = hostname@example.com
mail_plugins = cmusieve
}
auth_username_translation = %Lu
auth default {
mechanisms = cram-md5
passdb pam {
}
passdb sql {
args = /etc/dovecot/dovecot-sql.conf
}
userdb passwd {
}
userdb static {
args = uid=5000 gid=5000 home=/home/vmail/%d/%n
allow_all_users=yes
}
user = root
socket listen {
master {
path = /var/run/dovecot/auth-master
mode = 0600
user = vmail
}
client {
path = /var/spool/postfix/private/auth
mode = 0660
user = postfix
group = postfix
}
}
}
Folder structure
(For dovecot-acl)
/home/vmail/example.com/user/.Spam/dovecot-acl
dovecot-acl contains
owner lrwstiek
For me the config looks OK and I can't find an error...
When I change the dovecot-acl to "owner l" for example it seems that
this change has no effect.
Are there an error in my setup?
