It normally takes about 1-2 seconds per message for average
email delivery, depending of course on a number of things, such as message size,
internet bandwidth, DNS performance, system performance, the remote servers
ability to receive email, etc. etc. etc.

However, Postfix doesn't have to deliver them one-at-a-time, it can deliver
up to 1,000 at a time in a perfect scenario. The large scale systems I've
seen have only run at a couple hundred conncurrent deliverys. Your mileage
will vary. For performance tuning hints, see:
