+# vfile backend reads ACLs from "dovecot-acl" file from mail directory.
+# You can also optionally give a global ACL directory path where ACLs are
+# applied to all users' mailboxes. The global ACL directory contains
+# one file for each mailbox, eg. INBOX or sub.mailbox. cache_secs parameter
+# specifies how many seconds to wait between stat()ing dovecot-acl file
+# to see if it changed.

+  #acl = vfile:/etc/dovecot/global-acls:cache_secs=300
+}
+
+# To let users LIST mailboxes shared by other users, Dovecot needs a
+# shared mailbox dictionary. For example:
+plugin {
+  #acl_shared_dict = file:/var/lib/dovecot/shared-mailboxes
