There is no ACL inheritance feature in Dovecot at all. The only thing
that kind of appears as being inheritance is that when you create a new
mailbox, its ACLs are copied from the parent's (but any future changes
to parent ACLs won't change the child's.)

I've been planning on changing how global ACLs work though. The idea
would be that you'd have a single dovecot-global-acl file that has
fields:

<mailbox pattern> <ACL>

So for example you could say:

foo user=tss lrw

This would work the same way as now. But you could also add:

foo/* user=admin lrwstipekxa

This would also apply to the children. Still, none of this is really
"inheritance".
