I don't know if I'm just stupid or I really can't figure this out.
So I followed Lmp's guide to getting unregistered emails~
When I have my list of around 50 hotmails or so, I take around 8 emails and send an email to check if they're registered or not.
When I get the email saying "Delivery to the following recipients failed" and try to register the emails, it always says they're unavailable
Am I doing something wrong? xD
