Throughput = concurrency / latency.
What is your latency? Is it dominated by mail submission, by mail
delivery, or other? Postfix logs fine-grained delays information
that can help to find this out: Postfix logs "delays=a/b/c/d" where
a=time before queue manager, including time to receive the message;
b=time in queue manager; c=connection setup time including DNS,
HELO and TLS; d=message transmission time.
