This question has no answer, except to say that on typical commodity
server hardware you are unlikely to send more than ~3,000 msgs/sec per
Postfix instance. A queue-manager performance test I ran 2 years ago
showed that at near ~3000 msgs/sec, the queue-manager is working non-stop
and cannot go any faster (with a queue on RAM disk).
One might also add that throughput of 300-400 msgs/sec is realistic for
a Postfix system with low CPU overhead (no content filtering) and low
disk access latency sending mail to high capacity destinations that are
not throttling the traffic.
