This is probably not practical for one reason or other, and I haven't tried
it so it might not work, but you could try something like this:

Set up a LISTSERV list with the name of email address.  Example:  for an
email address [log in to unmask], create a list called
"john_doe."  Subscribe your customer under his/her real address.  Thus, an
email to [log in to unmask] would go to the list address (be sure to
remove this address from LSMTP's routing table).  Configure the list to
accept postings from non-subscribed addresses, but to require confirmation
from the sender (per LISTERV's approval mechanism).  Set the appropriate
template messaging to explain why the sender must click the approval link
or use the "ok" reply procedure.  The result would be that a sender who is
a real human being will approve the message, and one who is a spammer will
not.  One additional benefit would be if you were to set up an archive for
the list, your customer can now read his/her email from your web-based
archive system.

I have not tried to figure out the list settings to accomplish this and am
not even sure if it's possible to use LISTSERV in this manner.  Others here
with better expertise on LISTSERV might wish to jump in here ....
