dovecot - Aug 2017 - dovecot umask for mail boxes

I want to control the mode of newly created boxes.

The official documentation here: 
https://wiki.dovecot.org/SharedMailboxes/Permissions , under Permissions 
for new mailboxes says this:

"When creating a new mailbox, Dovecot copies the permissions from the 
mailbox root directory. For example with mboxes if you have directories"

But it seems to be untrue. I checked it, it soesn't work.

I found a topic in mail list archive:

https://dovecot.org/list/dovecot/2008-September/033395.html

Its recommended to create a 'dovecot-shared' file in each mailbox with 
proper rights. But how can I do that if mailbox is not exists yet ?

Can you provide any working solution to this problem ?

Hey,

Personally I always set the parent directory to have g+s (and group 
owner to "mail", or whatever you use for your dovecot installation),
and
this seems to do the trick.

I use mdbox, so it may be dependent on the backend being used for mail 
storage (mbox, maildir, sdbox, mdbox...)
