Okay, VERP has solved the bounce problem.  Now we need VERB (Variable
Envelope Recipient in Body) to solve the unsubscribe problem.
Basically, we need qmail-remote to merge the envelope recipient into
the message somewhere.  The problem, of course, is *where* to insert
it.  What I did for one customer is to insert it whenever a certain
magical character sequence was seen.  This worked for them because
they could ensure that that magical sequence only appeared where they
wanted it.  So how do we ensure that out-of-band data (the insertion
point marker) doesn't get confused with in-band data (the email
message itself).

In case it's not obvious what I'm getting at, imagine if you could say:
--
To unsubscribe, send mail to [EMAIL PROTECTED]

instead of the usual:
--
To unsubscribe, send mail to [EMAIL PROTECTED]
