Quoth RFC 1891:
This memo defines an extension to the SMTP service, which allows an
SMTP client to specify (a) that delivery status notifications (DSNs)
should be generated under certain conditions, (b) whether such
notifications should return the contents of the message, and (c)
additional information, to be returned with a DSN, that allows the
sender to identify both the recipient(s) for which the DSN was
issued, and the transaction in which the original message was sent.
Plus, there is the "Return-Receipt-To:" header which others have suggested
in this thread which works with some servers (it's in some versions of unix
sendmail), but isn't documented in an RFC.
The problem isn't that there isn't *a* standard for return receipts. The
problem is that there are many standards, none of which are widely
implemented. It also brings up lots of privacy issues.
