Email Gateway - Delivery Status
The delivery status shows either "Delivery successful" or "Delivery failed" but it also shows "Delivery successful" if just one recipient got the mail successful.
For example: if just one of five recipient gets the mail and it fails on four of them, it will show "Delivery successful". Maybe there should be a status like "Delivery partially successful" for those cases.
Is anybody at Sophos actually look after this kind of stuff? Email GW doesn't send NDR for non-existing emails. Due cost of AWS outgoing traffic ???
