Delivery to these recipients or groups is complete, but no delivery notification was sent by the destination server??
So recently I started getting these relayed message saying "Delivery to these recipients or groups is complete, but no delivery notification was sent by the destination server". My initial guess is that the destination server does not support Read/Delivery notification. But is it really that it?
I used to received read/delivery notification on almost every email just couple of months ago. After I upgrade to Outlook 2013 I did not implement the read/delivery notification as I was too lazy to get around to (no judging). So I start the read/delivery notification just after Christmas but I did not receive any notification to any domain. I tried gmail, yahoo, outlook, and many other vendors emails. What happened??
Anyone experience this issue? To make it simple, the read/receipt works when I sent an email to my gmail account.. but now it deliver this:
