Please do not repost the same question; I already answered this in the C# forum. OK, my answer got lost for some reason (mistake on my part). Generally speaking mail systems do not do this, as they follow the physical mail model. You post a letter but you can only be certain it gets delivered if you get a response from the person who receives it. It is not very efficient for a mail system to send you a message every time it delivers an email, and many messages may go to accounts that nobody reads; but there is no way for the mail system to know that. You can tag messages with a request for a read receipt, but that still relies on the recipient agreeing to send you one - I never do.

I just looked the C# forum to see your response, but there is nothing there? Unless there is another post with the same question somewhere else that you have answered? http://www.codeproject.com/Messages/3396503/identify-email-sent-or-not.aspx[^]

Weird or not? I'm usually quite careful to use the Preview, and reread my answer after pressing the Post button. I definitely wrote an answer, I can only assume that I was distracted and pressed Cancel for some reason.

The best solution that I can think of, is to embed a link an image URL into your email, so that the image is downloaded from a website. The URL in the email would be something like

http://www.yourwebsite.com/Image.aspx?i=logo&Id=YourReceipientsId

So basically what you are doing is referencing the Image.aspx page with the parameters of i=logo (parameter i = logo) and a unique Id for the Email/Receipient. What the Image.aspx does is record in a database that the Receipient has opened the email and downloaded the image, thus the email address is valid and been read. Then the page responds with an image.
