The session timeout configuration is inconsistent between YAML (60000ms) and Java config (20000ms in EmailSendingConsumerConfig.kt line 43). This could lead to unexpected behavior as the Java configuration will override the YAML settings.

Using println for logging in production code is not recommended. Consider using a proper logging framework like SLF4J with a logger instance.
Suggested change
| println(consumerRecord.value()) | |
| logger.info("Received message: {}", consumerRecord.value()) |

The return type 'Any' is too generic and provides no meaningful contract. Consider using 'Unit' if no return value is needed, or define a specific return type that represents the operation result.
Suggested change
| fun receiveMessage(consumerRecord: ConsumerRecord<T, K>, acknowledgment: Acknowledgment): Any | |
| fun receiveMessage(consumerRecord: ConsumerRecord<T, K>, acknowledgment: Acknowledgment): Unit |

These explicit imports from kotlin.collections and kotlin.text are unnecessary as these functions are available by default. Remove these imports to clean up the code.
Suggested change
