I guess the OP would have to come back and state what mail program HE
is using. And if he is using Outlook, whether return receipts are
turned on.

Delivery receipts are sent by the server (but that does not mean the
receipient read the message).
Read receipts are sent by the client app (Outlook) *if* the client is set to
send them (I always have read receips turned off)
Unless both you and the other side are using mail servers to store messages
that neither of you can control, nothing can be proved either way:
PST is a local file, and it is easy to have anything you please there, dated
any date you want.
