I am using Exim4 as my primary mail transfer agent.
I have sent a message and it currently resides on exims mail queue and will continue to be there for at least 5 days.
I believe a Non-Delivery report will be sent to me once every 24 hours telling me that my mail has not been sent.
Can I ask exim to send a Non-Delivery Report to me once every 6 hours instead of once every 24 hours?
So in a 24 hour period I would like to receive 4 non-delivery reports from my exim server telling me my mail is undelivered.
Is it possible to do this? Any links or information surrounding this topic would be appreciated.
