This is probably related. Using Outlook 2003. I actually received one of these things yesterday, tracking options are set to "always ask" about read receipts which request, as said, gets triggered even without opening (triggers in Inbox folder after selection without opening, when moving on to select another - I will try turning off preview to see if that makes a difference, would rather not though and all remote imaging etc. turned off anyway, 'locked-down', I would have thought). Anyway, denied it of course. They are definitely spreading ...
Then, more related, today, I selected and forwarded a small batch of spam in my "Junk E-mail" folder to my submit address (no read receipts requested from that folder) and almost immediately got a bunch of non-delivery notices. For (most of) the stuff I had just sent, including:

Disposition-Notification-To: <setkello1970[at]NEWCENTURYINS.COM>)
The failure notice for that one said:

Now, I have no control over the "disposition notification" but I thought I had full control over the read/return receipt. Obviously not, though what purpose these things are serving is even more questionable - maybe getting reporters pinged for "misdirected receipts".
Oh, and another manifestation of the read receipt I have seen (as said, I use the things in business, corporate standard) "Message deleted without reading" - after considerable delay.
Seems these scum are smarter than I am, have to start changing some Outlook settings before anything else happens.
[on edit - problems with my terminology. I said "preview" above. I don't have that turned on, never have had it on. I meant "reading pane", now turned off too, to see if there's any difference when tomorrow's batch of spam arrives.]
