WebSphere MQ Everyplace has a similar dead-letter queue concept to WebSphere MQ. Such queues store messages that cannot be delivered. However, there are important differences in the manner in which they are used.
The use of dead-letter queues with an WebSphere MQ bridge needs special consideration. Refer to the chapter on the WebSphere MQ bridge in the WebSphere MQ Everyplace Configuration Guide for more details.
