</span>t_relay() may return successful code if the message was put in the<br>
writing queue. Later can be another log message if sending ended int a<br>
transmission timeout. Do you have a failure_route set for such<br>
t_relay()? If not, you can add one, it should be executed if sending fails.<br>
<br>
