[exim] Message is locked (another process is handling this m…

Hi Sirs,



I'm getting messages locked on Exim Queue for a lot of hours, usually for
days and I need to restart Exim to clean the queue.



Below is an example of a message that is locked for 16 hours.



What I have to do in order to setting a timeout and send a message or alert
to the sender?



Many thanks in advance.
