Once again, you are assuming that a) the receiving site honours
return-receipt-to, and b) that the information returned will be
usefull for debugging purposes.  SCO MMDF return-receipts say
something like:

	Your message (message-id) was received by the following
	users or their agents:

		recipient
		recipient

The only way to reliably debug mail problems is to send mail to
postmaster@remote.dom.ain asking her to return your headers to
you.
