Short answer: It's not going to work reliably. Longer answer: You can request notification, but there is no guarantee that servers or clients will provide it. You may have more luck determining that the message was delivered to a specific mailbox on the server depending on the server used, but determining that the user actually got it and read it is close to impossible to do reliably. There are tricks and workarounds, like embedding web bugs, but even these are blocked by many clients (including Outlook) and are generally considered to be poor e-behavior.
Bottom line, not doable using SMTP mail. -----Original Message----- From: Robert Harrison [mailto:rob...@austin-williams.com] Sent: Wednesday, August 22, 2012 1:29 PM To: cf-talk Subject: cfmailparam I just found out (with no help from the Adobe documentation) that you can get an email generated via CF mail to return a read receipt by adding the following to the mail content. <cfmailparam name="Disposition-Notification-To" value="m...@domain.com"> This is the Message Disposition Notification - the command that requests the user to confirm they have read the mail. What I really want to do is confirm that the mail has been delivered. That should be something like: <cfmailparam name="Delivery-Notification-To" value="m...@domain.com"> or <cfmailparam name="Delivery-Status-To" value="m...@domain.com"> or <cfmailparam name="Status-Notification-To" value="m...@domain.com"> Does anyone know what the correct attribute is for Delivery Status Notifications? I can't find that documented anywhere.
