Hello,

I have developed a custom transport agent.  I am receiving a FAIL event each time the agent runs.  The Recipient Status in the Message Tracking Log entry has the following text:

: {[{LRT=};{LED=550 4.3.2 QUEUE.TransportAgent; message deleted by transport agent};{FQDN=};{IP=}]}

The messages are delivered without issue and are processed by the agent correctly as well.  It is not clear to me why this error is occurring.  I have gone as far as disabling the code that actually alters the message by commenting it out an re-compiling the agent.

Any ideas on what might be causing this kind of behavior.  Do I need to provide a return code from my agent that the logs would then read?

The complete tracking log entry is below.

Thanks

As a first step I would suggest you enable Pipeline tracing https://technet.microsoft.com/en-us/library/bb125018%28v=exchg.150%29.aspx and then look through the logs that its generates it should tell you why this is happening.

Hello,

I actually expect the message to be deleted.  What I was after is a way to add useful information to the tracking logs for the action that the agent is taking rather than having the Tracking Logs Suggest that there is a problem.

Ideally I would like to write useful information from the transport agent into the EventData property in the tracking log.

Thanks
