a "window" of a few thousand consecutive recipients in the queue file. If
no substantial groping is possible within such a window, it is not very
likely that significantly more grouping is available across "windows".
If the query that performs the alias expansion returns recipients sorted
by domain, Postfix will retain that order and group optimally.
