Re: [exim] Fwd: Rate-limit queue-processing per domain

I don't need duplicate individual mail to those on the ML.
Please don't.

You could certainly have a redirect router first in the
chain rigged to expand ::defer:: for anything after the
first few items. With current released Exim.

But you'd still be pointlessly doing this for all of the
spool that you weren't going to deliver. Hardly efficient.
