That's more likely to have an effect, but it still won't do what you're asking. Note that postfix connection reuse is time-based, not message count based. There's no way to explicitly limit to 20 messages per connection. You're probably better off leaving these at their defaults. And you still have a process limit of 1 in that line. You'll need to raise it if you want concurrency higher than 1. -- Noel Jones
