Hi Timo, I'm trying to share two folders. The first one it's public and the other is per user based, using acl's to control access etc . Dovecot create the folders, but when I'll subscribe using ThunderBird client both of them seens like watermarked and has a "mailboxes" folder inside. I can set up the acl's rules using Thunderbird. Log files like mail.log don't show nothing in special and mail.err has nothing. Here is the config. # 2.1.8 (b4cd382b6606): /etc/dovecot/dovecot.conf# OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.5 /etc/dovecot/conf.d/10.mail.conf namespace { type = public separator = . prefix = public. location = mdbox:/var/mail_shares/public:INDEX=/var/mail_shares/public subscriptions = no}namespace { type = shared separator = . prefix = %h/shared location = mdbox:%h/shared:INDEX=%h/shared subscriptions = no list = children} Thanks, Wagner Azevedo
