Did you make sure to put your own e-mail in the "to" field? The first time I used it, I CC'ed the right address and sent it to somebody but neglected to include my own e-mail.
I don't understand what rules they are using for where to send the reply. I'll go have another look.
Edit: Just checked - I think I followed their instructions. There was an incoming email with a link, so I forwarded it to them. Surely that should work. What should I do instead?
