I would, too.  (Sorry if this is an FAQ on the list; I've just started
reading comp.mail.misc.)  To start things rolling, here's one way.
You can put a line in the message header like this:

	Return-receipt-to: stefano@ecf.toronto.edu

The message you get back means the message arrived at the remote site,
*not* that the addressee read the message.  When I've done that, I think
the sites that answered all ran sendmail.  Not all sites do, of course...
