Different MX records for different email servers

I have two servers the Y (only for email), and I have Server Z (empty). - Y server has some registered email accounts; - the Z I want to register only 2 email accounts and use them without the intervention of the Y server. It is possible to configure two servers, and that they can receive emails normally with the same domain and without the conflict of both...? In short: each in its square?

Example: Server Y: [email protected] [email protected]

Server Z: [email protected] [email protected]
