There is no such document, and never will be. The above number is just ~6 msgs/sec, and you'll typically have a hard time finding hardware that struggles with such a small load. On modern server CPUs and disks, and given even modest network resources, your server should be able to sustain over 100 msgs/sec or ~9 million messages a day. Unless it is an outbound server sending primarily to Gmail.com, Outlook.com, ... where the destination imposes per-IP rate controls, or you want to run very CPU intensive anti-virus/anti-spam engines. Nobody else can measure and predict your load and constraints, which are unlikely to be determined by the hardware per-se. -- Viktor.
