I'll hazard a guess and say that the sender of the read receipt is most
likely the one who read the original mail.

That said, the handling of read receipts is entirely up to the
(receiving) client. Postfix has nothing to do with this aside from being
the messenger.

Postfix sends *delivery* notifications; for examples of these, see
the output from the "postconf -b" command.

*Delivery* notifications are send when mail is *delivered*.
