One of our clients have different requirement regarding SMG. They provide email relay services to their corporate clients who route all their outgoing emails to our client. Now the client wants to deploy SMG in their network for spam prevention and reporting requirements.
Question is how can we determine the licensing where client can only tell us email volume. Can anyone please guide me how much user license will suffice to cater requirement of 1 million emails per day.
Peak load hours are from 9am to 6pm which are 9 hours and if get the average of one million email by dividing it with 9 hours (32400 seconds) the we get 30 emails per second average. Lets say if we consider peak hours with higher loads then it may reach 100-300 emails per second.
Keeping all this requirement, what number of users license should client get for SMG.
