>From my standpoint, the problem with this "send an e-mail to confirm this isn't spam" approach is that it assumes everyone will
recognize the confirmation e-mail is legitimate.

Their program's lifespan is limited until the time either:

1) a spammer begins to use headers, subjects, etc. to look like the confirmation e-mail.

2) a virus writer creates a virus to look like the confirmation e-mail.  What a boon to virii this will be once everybody is trained
to respond to these e-mails.  Remember, they're already skilled in stealing names from your address book, so a note seemingly from
your good friend Joe saying "click here to confirm you send e-mails to me" is going to open pandora's box.

kind regards,
