Uh oh, lot's of mails to respond to. I'll start with this one and get to
the other ones somewhat later:

The reasonable response to latency spikes is creating concurrency

By design, Postfix MUST be able to run in a fixed resource budget.
Your on-demand concurrency spikes break this principle and will
result in unexpected resource exhaustion.
I'd second Wietse on this one.
If you throw in more resources for everyone, the bad guys are gonna
claim it sooner or later. You have to make sure you give it only to the
good guys, which is the same as giving less to the bad guys in the first
place. No need to throw in yet more additional resources on demand.
And that's also why it is important to classify ahead of time, as once
you give something away, it's hard to take it back.
