That's some very thorough information, you've provided plenty of context and clear description, which is great. While I lack sufficient knowledge to provide thoughts on the bottlenecking, I *do* expect that people will want to see the output of `postconf -n`, instead of your main.cf (to ensure we see what postfix actually sees and uses). Can you clarify what you mean by "500 smtp processes declared"? A sample output from qshape also wouldn't go astray either (http://www.postfix.org/qshape.1.html). You're provided some proportional figures (percentages), but some solid throughput numbers would be good too. Eg. "We're injecting 2 million messages to the postfix box, we expect to enqueue them in X hrs, but it takes Y hrs, and they're only leaving the postfix box at Z messages/sec". I see you said "I just found that Postfix could send 1 million emails per hour when I send less than a half million in 24 hours", but I can't make sense of that, sorry.
