Memphis’ dead letter station also serves the same purpose – it preserves messages that cross a specific number of redeliveries per consumer group, usually called poison messages. Poison messages are also called dead letters because of two reasons:

1. Regarding the broker’s transactions, messages are letters with a destination, just like actual, real-life letters.
2. The letters are dead since they didn’t reach their destination.

You can use the dead-letter station retransmit capability to

• Move the messages back to the source station with just a click of a button on the Memphis GUI
• Retransmit the message directly to the unconsumed consumer
• Consume the message directly through the SDK from any consumer
• Drop the message from the Dead-letter station
