Confirmation-needed emails by CDONTS

Hi,

I am using CDO for NTS 1.2 Library to send emails in a VB application. I
want to include the option which asks the email-receiver to send back
confirmation (Email was received by receiver) email. However I didn't find
any property or method for this feature in CDONTS object.

Is it possible to send the confirmation-needed emails with CDONTS? If not,
is there another email component/library which has this function?

Thank you in advance!

David

Are you aware that just because you ask for such a receipt you are not
guaranteed to get one?

And isn't that a feature of an email program rather than "protocol" (POP3 or
SMTP or whatever)?  I know very little about email protocols or anything
related, but it seems to me that CDO might very well simply not support
this.  You might have to use Automation with an email program that supports
Automation (like Outlook).  I know it's possible to request a read receipt
using the Outlook object model.

I sent myself a message with a read receipt and checked the raw contents. I
noticed this header:

Disposition-Notification-To: "Jeff Johnson" <my@email.address>

And yes, it's a function of the email client; nothing to do with any
protocols.
