Hi Does increasing the number of cores on the same hardware platform add performance to a Postfix system or it is better to run several Postfix systems on different machines? If the second choice is better, is it logical to run Postfix on different VMs (using ESX for example), let's say on something like 12 cores? I will use Postfix for email scanning (using Mail scanner) and relay and also for mail delivery.
