How to organize the exchange of messages between processes on the principle of mailbox?

Question

Message Queues

There are multiple processes on multiple machines. We need a messaging system based on the principle of a mailbox. One process sent a message to another (let's say all processes are named) and went about their business. The message went into the box, the second process woke up, checked the box, yeah - I got the message, read it, did what was asked of it, marked the message as read (committed). Processes can crash at any time, so a centralized server is needed to store messages.
I understand this is Kafka? Maybe there is something simpler for Python?
