Hi Daniel,
Thanks for the response. The question that's been raised by our engineers is how do we know the message that's put in the queue actually successfully been sent on the wire/network? Have there been situations where it gets stuck in the queue and never sent out?
once in the queue it may get discarded if connection cannot be established or because of transmission timeout.
Cheers, Daniel
Thanks. --Andy

Later can be another log message if sending ended int a transmission timeout. Do you have a failure_route set for such t_relay()? If not, you can add one, it should be executed if sending fails.
