These are much harder. Get a better outbound provider or
cut down your requirements or run your own outbound.

No doubt you will say noe of those are viable.

Next, define those more tightly - for instance: in any
one clock hour in the Pune timezone? Average exponentially-decayed
ona 10-hour scale? Then have a hunt in the Exim Wiki;
there's a page on possible routes towards outbound rate-limiting.
