The dead letter producerName uses this format:

---DLQ

Hey,
Pulsar messages have several metadata fields, including the name of the message producer. This metadata field is named producerName
The messages sent to the Dead Letter Queue also have a producer name, just like any other message.
The producer of these messages is named using the following format:
<topicname>-<subscriptionname>-<consumername>-DLQ
I hope this is clear now. Please let me know if you have any questions.
By the way, it might be necessary to clarify the docs here. @startjava are you willing to suggest an improvement? That would be amazing, and super useful to the community!
