[Dovecot] can not see public mailbox

[David Mehler]

Hello,

I'm running Dovecot2 and trying to set up public mailboxes. I've got a
virtual user system set up with postfix and using MySQL
authentication. I'm wanting to create several public mailboxes for
shared messages. I've followed the wiki and have the public folder
created. I've got a folder /home/vmail/public/public1 public1 being
the maildir of the public mailbox.

I can see in my folder list of my webmail client the root public
folder but I can't change in to it and I can not see the public1
public mailbox.

I'm using one user vmail set up for this setup, permissions on the
public1 folder allow the vmail user to read and execute.

In public1 I have a file dovecot-acl which has the user attempting to
access the public folder with the flags l and r.

Below is my config with doveconf -n. I'd appreciate any suggestions.

Thanks.
Dave.
