message_expiration

message_expiration — the time to live for messages

Message_Expiration = 604800

The maximum amount of time in seconds a message will remain undelivered in the system. If a message remains undeliverable for this amount of time, it will be removed and a delivery failure log entry will be made. If the Generate_Bounces configuration option is enabled, then at failure time an out-of-band bounce message will be generated and queued for delivery. The default value for this option is 86400 seconds (24 hours). However, in the default ecelerity.conf file this option is set to 604800 (1 week).

message_expiration is valid in the binding, binding_group, domain and global scopes.
