Dear all, I am hoping someone can help me with a problem that I have been trying to fix for days. Using postfix and dovecot 2.0.19 on Ubuntu 12.04 with LDAP authentication and virtual users and domains.

Basically I want to setup both shared and public mailboxes. The shared part is working fine, ie I can share folders successfully and other uses can see them. However when I try and create sub folders in the public folder they don't show up in the client. I have tried creating them in manually in the filesystem ie mkdir .folder and also via thunderbird. I have read through the dovecot wiki's several times over and still cannot see why it won't work. I have debug turned on and these are the log messages I get in syslog when I start up thunderbird:

acl: No lookup right to mailbox: public/folder

acl vfile: file /home/example.com/public/.folder/dovecot-acl not found

acl vfile: file /home/example.com/public/dovecot-acl not found

So I create the dovecot-acl file manually in public and set the right file system permissions and the errors go away, yet the folder still doesn't get created despite the following getting logged in syslog.

Jan 29 23:43:57 alpha dovecot: imap(testuser@example.com): Debug: Namespace public/: /home/example.com/public/.folder2 doesn't exist yet, using default permissions

Jan 29 23:43:57 alpha dovecot: imap(testuser@example.com): Debug: Namespace public/: Using permissions from /home/example.com/public: mode=0777 gid=-1

Right now I am thinking the problem might be that I am trying to setup both shared and public namespaces within the same configuration and therefore dovecot is looking for acl's for the public when it shouldn't be? Feel like I am stabbing in the dark with this though.

Any help anyone can offer will be greatly appreciated! Thanks in advance.

Regards, Michael.
