“Delivery to these recipients or distribution lists is complete, but delivery notification was not sent by the destination”

Question : “Delivery to these recipients or distribution lists is complete, but delivery notification was not sent by the destination”

Can someone tell me what this means:
“Delivery to these recipients or distribution lists is complete, but delivery notification was not sent by the destination”
This is the response sent from a user who sent email to our Imail email server.

Thanks


 

Solution: “Delivery to these recipients or distribution lists is complete, but delivery notification was not sent by the destination”

It sounds like someone had marked “Request a delivery receipt” for the message but the mail server is incapable of understanding that logic so it delivered the email but ignored the receipt message.
