Hi All,

I am using Python based paho mqtt client.

On publishing the message if "qos=1", then mqtt client will store message temporary until all retries attempt to send out the messages done and after which it drops that message.

SO I WANTED TO KNOW IS THERE ANY CALL_BACK OR FLAG WHICH GETS TRIGGERED ON MESSAGE EXPIRE.
OR
Is there any other way to know about such messages, which is getting drop without successfully published to broker.

I wanted to store such message in some external file.

Thanks in Advance :)
