You cannot subscribe to the root folder of a namespace. I'm not entirely 
sure *why* this is the case (it seems to be generally desired, and it's a 
common source of confusion), but it's the way Dovecot's set up (Someone 
correct me if that's wrong in the 1.1 series).

You should be able to subscribe to any subfolders, though. e.g. based on 
the permissions in your example:

mkdir -p /home/vmail/public/.folder/{new,tmp,cur}
touch /home/vmail/public/.folder/dovecot-shared
chown -R vmail:vmail /home/vmail/public/.folder
find /home/vmail/public/.folder -type d -exec chmod 700 '{}' \;
chmod 644 /home/vmail/public/.folder/dovecot-shared

Then you should be able to subscribe to public/folder

I'm not sure how ACL's play into this. The lack of hierarchical ACL's 
prevented them from being useful for my situation, but I had the benefit 
of system users (so I could put them in groups and control access that 
way).

Best,
Ben
