How about this:  Put a link "to unsubscribe click here" at the
bottom of every mail you send out.  That link has the
subscriber's email address embedded in it, and it leads to a CGI
program which checks (by means of a reverse DNS lookup) whether
the IP address from which the click comes belongs to the same
domain as the email address for which unsubscription is

If yes, unsub immediately.

If no, require email confirmation for the unsub request.
