smtp delivery receipt

[Keith G Hicks]

I'm confused about this. I have a routine that sends out some mail messages
and all that works fine. I want to have the messages go out so that they
request read AND delivery receipts. Here's what I've done:

From what I've learned, the first line lets me add a request for a read
receipt and it lets me specify to whom that receipt goes. Is this correct?

EmailMsg.Headers.Add("Disposition-Notification-To", mainDLNPSender)

Second, all I found on delivery receipts was what I did below. I'm guessing
that the receipt would go to the SENDER or is it going to the FROM? Or is it
going somewhere else? Is there a way to specify who gets the delivery
receipt like I did above with the read receipt?

EmailMsg.DeliveryNotificationOptions = DeliveryNotificationOptions.OnSuccess
+ DeliveryNotificationOptions.OnFailure

Thanks,

Keith

Well I tested something in my own email outside of my vb code. I sent a
message via Outlook to one of my other email addresses and checked the
Delivery Receipt box. I tried that with 3 of my addresses. No delivery
receipt. I hunted around online and found that it's nearly useless since
many mail servers don't acknowledge delivery receipts. So even if I could
change the person the read receipt gets sent to, I'm guessing there's not
much point in even dealinng with it anyway since we hvae no control over
which email servers respond and which ones don't.
