I did wonder briefly why this feature had to be explicitly switched on
- this explains it, of course.

I strongly agree. This was handled badly to start with - for which I
am partly responsible.

I know about the Received: headers - the person complaining didn't,
but I managed to get him to find them and send them. This adds to the
case, as from what I can see, the address that was forwarding to him
looked rather like a spam address. I don't pretend to know why
spammers would set up re-mailing addresses to target some addresses
they've harvested, and then use those same addresses to register on
random websites, but it looks as if that's what happened here. So not
only should we have explicit consent, but there is also a case for
captchas or some similar system for at least reducing automatic
registrations.
