What configuration do you recommend based on our company's current number of users and concurrency?

This needs to be configured according to the customer's situation. If the number of users is less than 1000, a single machine is sufficient if high performance is not considered. However, from the standpoint of performance, ease-to-use, and stability, the layout is two fronts-end and one back-end. Due to the large memory usage of the mail system, it is recommended that the server be configured with higher memory. 64G is generally recommended, and an eight-core CPU is recommended.
