sharing a folder with all users in a domain

Hello,

I'm wanting to make a shared folder that anyone in a domain can get to, but not anyone in any other domain.

Here's my dovecot shared namespace:

namespace { type = shared separator = / prefix = shared/%%u/ location = maildir:%%h:INDEX=~/shared/%%u subscriptions = no list = yes }

The dovecot-dict-sql.conf.ext file has:

map { pattern = shared/shared-boxes/user/$to/$from table = user_shares value_field = dummy

fields { from_user = $from to_user = $to } }

map { pattern = shared/shared-boxes/anyone/$from table = anyone_shares value_field = dummy

fields { from_user = $from } }

and in my global acl file I have: shared/office@ user@domain.com lrwstipekxa shared/office@ user2@domain.com lrwstipekxa

Thanks. Dave.
