Can I define retry mechanism for RabbitMQ message producer in SpringBoot?

Question

I have the following RabbitMQ setup in the application.yml in my SpringBoot app which can consume (receive) messages:

spring:
  rabbitmq:
    host: localhost
    port: 5672
    username: admin
    password: password
    listener:
      simple:
        retry:
          enabled: true
          initial-interval: 3s
          max-interval: 10s
          multiplier: 2
          max-attempts: 3

I want to create a different SpringBoot app where I can only send the messages.

My questions:

1. is it possible to define retry setup for message-sending?
2. if yes, is it the same as my example shows? since it is named listener: spring.rabbitmq.listener...

Thank you!
