Clients connect to the Client Access Services. It resolves on what Database the Mailbox is and what Server is responsible for that Mailbox Database and proxies the connection to the Backend Services.

Hello Andres-Bohren,
but I try to find how Exchange servers communicate between themselves.

Intra exchange communication is a bit of a mystery. There are hidden connectors created with each new Exchange server installed into an organisation for intra-organisation communication (and you can only have 1 exchange organisation per forest/domain).
