So clearly you've given more than necessary permissions in here. 0600 with user=vmail should be enough. But the permission problem isn't on the server where you ran this "doveconf -n". The problem is on your remote server's Dovecot config.
BTW:
unix_listener auth-master { group = vmail mode = 0660 user = vmail }
There's no reason to change this from defaults.
