No. There is an existing solution that works for multi-recipient
list mail. That solution does not work for single-recipient list mail,
which we suspect is your use case.
Viktor proposes to schedule single-recipient list mail from the
same sender as if it is multi-recipient list mail (post-facto grouping).
I'm proposing to just put a cost on each delivery request, initially
based on how many other requests a sender already has in flight,
that decays over time until the request is selected for delivery.
This guarantees that all mail will eventually be delivered.
This also would give us the option to make the scheduling dependent
on message size, or quality-of-service indicators.
